BASi PWR-3 Power Module
The compliance voltage and maximum current of BASi PC-controlled potentiostats are 12 V and
100-200 mA. These are more than sufficient for most voltammetry experiments, but may not be adequate for controlled potential
electrolysis experiments. The PWR-3 Power Module supplies up to 1 A with a compliance voltage of 85 V, and can be used either as a
current and compliance voltage booster for other BASi potentiostats or as stand-alone potentiostat for constant potential
experiments (i.e., it has no potential scanning capabilities). Another advantage of the PWR-3 is the unique design of the
current-to-voltage converter, which eliminates the potential loss at the working electrode caused by high current through the lead
wire.
Features

- Remote control from Epsilon
- Unique current-to-voltage converter design prevents loss of potential at the connector at high currents
- Economical - high performance at a low cost
- External applied potential input
- Excellent frequency response to 20 kHz
