QDoes the current limit control affect only the 30V output, and what current range does it provide? ie does it have a 0-30v / 0-10A output
AHi Duncan. Thank you for your question. The current is limitable 0-10a. This has an effect on the 30V output only.

QYou claim "Can be used in either Constant Voltage with Current Limiting or Constant Current with Voltage Limiting Modes, Current Limiting LED Indicator, Adjustable Current Control". The manual gives no mention to the 2 modes. Can you explain how this achieved.
AThanks for your enquiry Dave. These are options which can be found on the front panel. It offers a 12 or 5v output limited at 500ma or an output that is adjustable to up to 30v DC at 10 amps.

Stable operation, relatively high current output compared to other PSU's in a similar price range and so far they've proved to be very reliable. I've bought 3 of these over the years and they're in constant use on various projects with no issues. Only downside is the rather noisy mains hum from the very chunky transformer inside but if its being used in an active [read noisy] lab/workshop environment this won't be noticeable.

Nice power supply. The three outputs seem to be isolated from each other and from ground. The panel meters are reasonably accurate. It's linear so contains a big bulky transformer and voltage regulator transistors bolted to a big, forced-air cooled heatsink. I wasn't expecting it to perform to specification and actually provide 10A continuously but it seems fairly stable driving 11.3A into a short circuit. Set it to 13.8V and it's perfect for driving your amateur radio/automotive equipment. The current limit is useful for testing: crank the limit up until something happens. One design flaw with this power supply is that it has a big line frequency transformer in a steel box, which makes it quite loud: a lot of mains hum. The cooling fan generates more noise still but i suppose that's unavoidable in a linear power supply of this spec. It doesnt switch on all the time, there seems to be some sort of thermal control switching it on and off. The constant voltage outputs seem to just be a simple transformer --> bridge rec ---> 78xx linear reg arrangement. I'd recommend this psu if you can put up with the size, mass and noise.
