Does anyone recognize the programming terminals on the real panel of this power supply? I would like to get the 50 amps out.

It is an ATE1 made by Redfern radio, it is an old army surplus.

Going in blind I have placed a 10k resistor from the +15 to the Vp and Ven allows me to get 44 amps max into a 0.5 ohm load. Vp seems to be clamped at 7.5V, even if I drop the resistance of 10k resistor connected to it.


front panel

rear panel

  • \$\begingroup\$ manual would be hard to find for army supplies. If they followed vintage HP methods of PSU control, the voltage and current programming would be in x Ohms/volt and y Ohms/Amp \$\endgroup\$ – Tony Stewart Sunnyskyguy EE75 Mar 14 at 2:39
  • \$\begingroup\$ You might be on to something there, however the notation is different, HP machines seem to have A1,A2,A3... etc. I am trying to operate the supply locally using the front panel. I could just be that the supply is no longer capable of the original ratings. I can get max 30V or max 42 A but would really like to get the 50 A. \$\endgroup\$ – gchizzle Mar 14 at 4:43
