If you don't have the remote plug inserted into the blue DB15 connector near the transformer, the power supply won't work. If you don't have the 'Interlock' connection link on the DB15 connector, the power supply won't work.
Gta San Andreas Ntdll. If the remote plug is not correct, the supply will just display 0. None of the control pots will change the display. If the remote plug is not correct, the supply will just display 0. None of the control pots will change the display. If the remote plug is OK but both sets of output leads are not plugged in, the Voltage, Current and Power pots will change the display and you can set up to V and mA and W respectively, but the High Voltage LED on the front panel will not light and there will not be any output.
Technical Reference Documents I had been looking for technical material for these discontinued power supplies for some time, with little success. These units are very reliable and are still in use in many scientific facilities, however the manufacturer or its susidiaries are no longer referring to them on any of their web sites. Over a number of years, I have been contacted by a few technical people who have also been looking for this information, and between us, many thanks to them we've been able to locate the following: LKB Instruction Manual.
I want to know if anyone has complete service-manual for this supply? From looking at the innards it's apparent that it's a very interesting and alternative build.
I'd like to see exactly HOW it's done, stabilizing this wide output-range. The thing is built like a tank, long before parts came from China and all electrolytic cap's are measuring like new. Probably not very difficult to service if need be. Dear Tri-comp What a blast from the past. I used one of these over 30 years ago for clinical research electrofocusing. It was very reliable. Of course, the voltages are potentially lethal. I wonder whether a friendly engineer there might help.
Good luck Best wishes Anthony. I have been working on and off converting a similar supply for use as an HT power supply. Have a look at the block diagram fig 4 The output is generated by 2 rails in series. The centre point is earthed see the symbol just above the current sensing resistor so that each output terminal will be at half the output voltage above and below ground. The only protection is that if more that 0. Another possible problem your supply may be different to mine in this respect is that the time constants on the regulator circuit is very long.
As a result when the output is switched on or the supply comes out of current limit the voltage goes very high for a fraction of a second. I have sent tri-comp a PM, hopefully he will read this before connecting the supply up. Edit: Just fol clarity. The internal ground does not float, it is linked to mains earth via the diodes and resistors that make up the earth leakage detector. Al, I'm still alive ;D The power-supply is taken apart while waiting for 3 new Bourns pot's.
I'll be using it as a bench power-supply when breadboarding with valve-amplifier design. It will never be used as a permanent supply. I actually read about the symmetrical output in another user-manual for a similar supply before I settled on buying this one.
I suppose I'll just have to keep the power-supply chassis away from other instrument cases and I'll be fine. Also don't reach for the scope with one hand while adjusting the power-supply with the other. I'll report back with my findings once it's re-assembled.
