  • This is absolutely top notch; a beautifully compact, and functional, bench power supply.

  • Great Value for money exactly what I need for doing college Electronic assignments at home.

  • Excellent delivery - within 24 hours of placing order. The unit is smaller than I expected. A professional looking piece of kit. Very easy to use. I particularly like the output on/ off switch. Very useful. At the special price, anyone looking for a bench power supply could not do better than this.

  • Nice price (on promotion at £64.99) and by ordering another product, took the order up to over the voucher threshold, so a nice £7.00 voucher discount off the total price. Small, compact, works well. Glad to see mains lead and output leads are included. As another reviewer has said, it does present a load of 600 Ohms or so when switched off, so be careful when charging batteries as you don't want to discharge them inadvertantly. A solution would be to add an external (or internal, if I can get the case off) Power MOSFET in the supply, connected as a Diode. STP36-NF06L does the job and drops just 2.5mV, a much better solution than a reasonable Shottky Diode (like 1N581) at 0.2V! Niggles, that's all. Voltage adjustment a bit slow and fiddley as the display takes a few seconds to settle down.

  • Nicely constructed with a clear LCD. Setting of voltage is a little vague and current setting isn't retained when switched off but when set works very well.

  • Great value product. Only problem is that settings are too course to obtain the advertised setting resolutions for voltage and current. Clearly a fine adjustment control is needed. Overall the unit has proved reliable, runs cool and is stable in operation.

  • I was really pleased with the N93CX power supply, it is fully adjustable from 0 - 20 Volts & 0 - 5 Amps. The case has a proffesional & pleasing appearance. The LCD screen is bright & has large numbers. Really good value for money.

  • First class small bench power supply

    Was this review useful?  Yes No  1 1

  • I use the unit for examining behaviour of circuits under varying supply voltages : so I want to set an accurate voltage. This unit is rather coarse for doing that i.e. setting 7.5v as opposed to 7.3 or 7.6. The same comment holds for current setting. I think it represents fair value when on offe. In all other respects the kit is good.

  • I use the power supply for various home projects, it works very well, no problems so far. The current limiter is a very usefull feature it saves things being "cooked" if you get your wiring wrong. Also great for charging nicads or nimh batterys.
