Sorensen / Elgar 33V 33A Programmable 1kW DC Switching Power Supply, model number DCS33-33E M1 M13.
These are new/surplus units that were removed from the box and stored on a shelf.
They do not include a printed manual and they show some very slight shelf wear.
This model of power supply includes option M1, meaning that it is pre-wired for 120VAC input.
By adjusting an internal jumper, the supply can be easily rewired to accept 240VAC input.
See product manual for details.
These units also come with the M13 option for locking controls.

Manufacturer's Description:
The DCS Family of 1 kW, 1.2 kW and 3 kW programmable power supplies incorporate current mode switching rates up to 100 kHz in high power density, low profile chassis. Utilizing unique packaging techniques, the DCS Family provides continuous full output power (1 kW, 1.2 kW or 3 kW) in any volt/amp combination within the rated output voltage and current limits.
This family has 10-turn potentiometers to adjust voltage and current settings that are displayed simultaneously. LEDs indicate overtemperature, remote programming, shutdown and overvoltage protection, status and constant-voltage/current mode operation.
