Om SB15-20

The Switchbox SB 15-20 is a bench DC power supply made by Powerbox AB of Gnesta, Sweden. Powerbox was founded in Gnesta in 1974 and is now part of the Cosel group. The name and markings on the front panel identify the unit; no published datasheet for it was found.

The front panel has a multi-turn dial for the 0-15 V output voltage and a second knob for the current setting. CV and CC lamps show the operating mode. Output is on red (+), blue (−) and green (earth) 4 mm terminals, beside an on/off switch and a power lamp. Two meter windows sit above the controls. At the rear are an IEC mains inlet and the fuse ('Fuse at rear').

The '15' in the model name matches the 15 V output. The current rating is not printed on the visible panel, so it is not stated here.
