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
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.

Can I use the green ground port to ground myself with an antistatic wristband when dealing with devices that are sensitive to static electricity?
could this be used to power a car radio head unit?
will this support 21.6v and 1060mvh
What is the operating temperature range? I wolud like to use the power supply in a cold room (3-8 C), so would that be possible?
Is the tag fitted at the back of the unit a connection point for chassis earthing? Regards Brian
Do you stock spare parts for these units
what is the short circuit protection, a fuse or a circuit breaker?
can this be used as a split rail supply - say, +/-20v - I notice the green "ground" terminal?
