Om B202

The Oltronix B202 is a linear laboratory power supply from the Swedish maker's LABPAC range. It has two outputs, positive and negative, around a shared 0 terminal, so a single unit gives a split supply for analogue and op-amp circuits.

Each side has a 10-turn voltage control covering 20 V (0.4 V per division) and a current-limit control from 0 to 2 A. Two lamps per side show whether that output is in constant-voltage (CV) or constant-current (CC) mode. A twin-scale analogue meter shows each side's voltage (0-20 V) or current (0-2 A), switched with a Volt/Amp button. With the tracking switch on, one control sets both outputs together. The front panel also has a separate ground terminal, the mains switch and a 1 A slow fuse.

Radiomuseum.org lists the B202 as an Oltronix AB (Vällingby, Sweden) model from about 1974. It gives 0 to ±20 V at up to 1.5 A in tracking mode, or 0-20 V and 0-(-20) V at up to 2 A each when set separately. The case is a narrow extruded-aluminium tabletop housing with a fixed mains cable. This is a discontinued vintage instrument; Oltronix production in Sweden ended in 1977.

Vanliga frågor

Can the B202 give a symmetrical ± supply?

Yes. It has positive and negative outputs around a common 0 terminal, and with the tracking switch on both sides follow one setting.

How much current can each output deliver?

The current controls go up to 2 A per side. Radiomuseum lists 2 A per output when the outputs are set separately and 1.5 A in tracking mode.

Is the B202 still made?

No. It is a vintage Oltronix LABPAC model from the 1970s, and no current successor is named.
