Power supply load unit

The Motech PPS-120X GSM series dual channel DC source/current sink power supply/loads are suitable for testing mobile phone and other battery operated equipment, especially systems incorporating rechargeable batteries - in this case the device supplies charging power while checking battery drain at the same time.

All power supply/load units have two output channels which can be configured as either DC volts and amps out or DC current sink.

Three models are available in the range, two of which (PPS-1201GSM/-A) have programmable voltage and current outputs of 0-8 and 0-3 A and a sinking current range of 0-3 A.

The third model in the range has outputs in the range of 0-18 V and 0-4 A, and a sinking current range of 0-4 A.

The PPS-1201GSM-A has a low current range as well as sink from 0 to -3 mA (sink) and 0 to +3 mA (source).

The PPS-120X GSM series has a GPIB interface, electronic calibration via front panel controls or the GPIB port, output enable/disable, remote sensing function and power-off memory.
