About this product


  • DC 0 - 30V (2.5A), fixed DC 5 and 12V (0.5A) outputs
  • Separate analogue voltmeter and ammeter
  • Current can be limited from 0 to 2.5A using the ‘current’ control.

Product overview

• DC 0 - 30V (2.5A), fixed DC 5 and 12V (0.5A) outputs• Separate analogue voltmeter and ammeter• Current can be limited from 0 to 2.5A using the ‘current’ control.• Fixed outputs through ‘snap-on’ terminals and variable supply available at pair of terminal posts• Overload and short circuit protected

Rated 5 out of 5 by from Good solid power suppy, with great features. I bought two of these and as I have had almost identical units before, I knew they were going to be OK. I like the analogue meters, and the ability to set a current limit.

Rated 5 out of 5 by from Nice traditional power supply. I have been very pleased with this power supply. I had been looking for one for a while now, but didn't want to pay about a £100 for one. At this bargain price, you have to buy it ! It's a very good product and nicely made, and does everything I wanted.

Is this a switched mode supply or a pure analogue / linear supply? Will it be able to supply 5v with 2.5amps

Asked by: MGM1956
Yes, you would be able to do 5v at 2.5 Amps with this device.

Can you use the 5v fixed and the 0-30v outputs at the same time? What would be the current limit(s)?

Asked by: Mark
I'm afraid it is only single voltage on each , below are current limits : Output Voltage: DC 0 - 30V (2.5A max) DC 5V (0.5A max) DC 12V (0.5A max)

Can this unit be used as a rectifier for copper plating and electroforming.

Asked by: Clubhead
Unfortunately we are unable to guarantee full compatibility for this item in your intended application, as this is not the manner for which it was designed to be used.
