ADX Electronics must abandon Itech agency >>>>

Update 07 December 2016: Itech programmable power supply quit stock

To past customers of ADX Electronics' Itech products:

Since 2004 my company has been the proud distribution and support agency for the ITECH range of power supplies and electronic loads in NZ. I am glad to have been part of a driving force behind the way these types of products have been raised all the way from "too cheap" to "too expensive" - to put it bluntly. Itech are now the OEM for traditionally-respected brands like Tektronix and Keithley. True I had seen a general slowdown in sales (a victim of that success, if you will).

However, as a result of recent law changes, my company has been forced to abandon the ITECH agency entirely. Companies where an owner is related to a person with a disability are effectively no longer open to hold stock. MSD now dictates the commercial operation of such companies, and requires tax returns etc (where for most companies this is administered by the IRD). It would be inappropriate in these circumstances to try to hang on to a distribution agency. We had two cases in the High Court, but they were abandoned due to the type of corruption I didn't think existed in New Zealand.

If I may make one request to anyone reading this: Please be very, very careful who you vote for. I'm not at all suggesting any kind of political leaning, the issue is deeper than that (this is not a business vs the workers thing, obviously). It is about needing to keep a close eye on what is happening to your country, before it becomes something you struggle to live with. I'm not known as a political person, but these are desperate times for many people, most who have no voice.

Anyway, my company has some stock left, I was hoping to retain some for warranty purposes even after abandoning the agency, but I now need to quit most of it, fairly fast. Therefore I would like to offer it to existing customers before I stick it on Trade Me (my username there is "adx"). That way if you rely on a particular model for some mission-critical function, you may be able to get another at a discount, from stock. First come first served, I'll entertain offers after a few days, and will post stock updates at the link below. Sorry, no loads available, just a few models of power supply - as listed below.

The company which picked up the agency is Fuesco, who cover the AU/NZ region. You will have to ask them about their stocking and warranty arrangements, however I doubt they will provide free warranty support for product I have sold. I suspect Itech in China would honour any warranty arrangements (1 year) on unused stock through assembly/board replacement (which is how they worked with me) as a last resort, however don't expect to hold me (or them) to that. I don't plan on going anywhere, but that may be beyond my control in this political climate. Feel free to attempt to contact me about anything I have sold, for all eternity.

Note some of these units are over a decade old. This is a natural by-product of having stocked 30 different models and variants. Itech have always stood behind these as if they just built them a week ago. All are brand new, and as has always been my policy, new units are new and have never been on demo or in use. I may add used or repaired units to my site or Trade Me. I am at maximum capacity shutting down business operations to meet the new regulations, so if you are interested I will go to my factory and test the unit(s) before sale, and recalibrate if necessary. Prices include isolated comms module, I only have 5 USB comms modules in stock so it's first come first served for those (the remainder will need to be replaced with RS232, or buy an "IT-E132" from somewhere, or lash up a UART interface). Shipping is via the usual PBT couriers except the heaviest unit(s) will need to be freighted at your cost.

Sorry for the long email but this is a complex situation. Please accept my company is not in liquidation or anything of the sort. It's the law, now starting to be applied across the board. The law cannot be challenged by companies. Absolutely nothing can be done (except what I said about voting), please understand this is New Zealand Government policy, the "normal" checks and balances that (arguably) used to exist in NZ to prevent this sort of thing are now gone.

I am glad to have been of service, and many thanks for your support over the years. I hope you appreciated my engineer's approach to things.

One more request: I am generally available for contract work especially for any PCBs you might need designed. My company is permitted to retain Altium 13 (version it was on before the restrictions came into force without warning), which is still quite interoperable with at least version 16, and the restrictions against contract work are generally less draconian (however please understand MSD operate on 100% discretion, whereas the IRD operates on rules). I will let clients know if any silly restrictions affect your work - for PCB designs this is unlikely. I don't want to seem "unbusinesslike" but please accept I didn't write the law, and as an engineer, being up front about my consulting work is a matter of professional ethics.

Many thanks - Antony.

Effective 03 April 2016: Due to new restrictions imposed by the New Zealand Government on companies where an owner is related to someone with a disability, ADX Electronics Limited is no longer reasonably open to hold stock. Therefore the company had no option but to relinquish the agency for the Itech products, it would be an untenable position for a distributor to pretend otherwise.

Remaining stocks will be reduced until they are exhausted, retaining some units for warranty.

However I will still support the products purchased by my customers over the past 12 years to the best of my ability, and in no way wish to abandon my customers (many of whom are also contracting clients). This is also in no way a reflection on Itech or their products, which have generally been excellent. Please understand this is a Government restriction, and a side-effect of an increasingly nasty worldwide trend.

The web shop mentioned below is currently inactive for security reasons. Since its only real purpose was as a catalogue for the various Itech models, it's best left off while I sort out remaining stocks. In the mean time if you have an enquiry please use the email link as described below.

ITECH products >>>>

Itech manufacture a wide range of programmable linear DC power supplies and DC electronic loads. These are professional grade instruments suited for automatic test and high volume benchtop use - with build quality comparable to the big name brands. However Itech's products are vastly more cost effective, due to their Chinese origin and my thin margins - in fact the price is only slightly higher than the popular Topward brand adjustable (but not programmable) lab power supplies. This isn't to say Itech is the cheapest option these days - taking this dubious honour are no-name lab supplies (that often have serious flaws), and a few brands of cheaper build programmable supplies that have appeared in the past few years.

Please note that despite the fact we used to manufacture similar products, these ARE made in China (now part of the very large B+K Precision group of companies), and beyond being a service agent and providing the odd engineering insight, the design is beyond my control. They are a popular brand domestically in China, frequently specified for factories etc when they are offshored (to China) - which distinguishes them from many of the cheaper brands (built to a price to satisfy export demand). These cheaper programmable units definitely have their place, but there is a difference.

Most of my customers are local to NZ - educational institutions, small companies, or the odd large manufacturer that took a punt on my products after some budget squeeze forced them to consider alternatives to the big brands - no small thing when millions of dollars of production relies on correct functioning of test equipment and price is usually no object. Invariably they buy more, and more, and more...

best price >>>>

Please look in the web shop for current pricing (note: GST inclusive).

Latest pricing note: For the time being please disregard the 2005 pricing in the brochures and tables below. I was able to retain this for many years (mainly through reductions in discounting), but ongoing cost increases and recent economic conditions eventually had their impact on pricing and demand. I increased the web shop prices by only a nominal amount at the time, now that the exchange rate has recovered these prices should be fairly stable.

price and availability >>>>

Prices and stock quantities are generally available on the web shop, however feel free to email and check.

demonstrations >>>>

I am happy to send you a demo unit. If you are a clearly established business, it won't need to be paid for up front.

I ask that demo units are looked after aesthetically and not subject to undue abuse. However go for your life in checking out how electrically rugged they are (within reason) - because they are.

Our policy is to NOT sell demo returns to other customers as brand new, as we can not be 100% certain of their past, so depending on your level of interest, I may send a demo unit, or a brand new unit. Please keep this in mind. (I can do this because few (if any) units sent for anything other than an obviously casual interest are ever returned.)

All this is done entirely at my own discretion, so don't be offended if you are refused credit, or can't really afford to pay for a demo unit. We are not set up to hire out units.

ordering and freight >>>>

Basically: After you have emailed for price and availability, just email your P/O. (Conditions apply as below.)

warranty >>>>

The ITECH range comes with a 1 year manufacturer's warranty. I am the New Zealand agent. I'll usually extend this myself, because I know how the products work, can service them locally, and they have generally proven to be reliable. Due to the low number of faults (for a number of years there were no failures at all), I have generally been doing this by replacement for the smaller products.

To honour a warranty claim I'll need the faulty product returned beforehand for diagnosis, and to guard against abuse of the system. However this can be relaxed if you are a well-known customer. If you have a mission-critical application (eg 2 shift high volume ATE), please discuss options for protecting yourself against potential outages before ordering.
