TAKASAGO Bipolar Power Supply BWS Series | PT. NIHON DENKEI INDONESIA Jakarta

4-quadrant bipolar power supply BWS series

Power can be supplied (source) and absorbed (sink) ・Standard type, constant voltage (CV) and constant current (CC) can be used. It is possible to drive at the maximum current even with a load with a power factor of 0 for testing of inductive and capacitive loads, magnetic materials and DC servo motors, power amplification of function generators, etc. Output can be controlled by independently setting 4-point voltage, current limiter and external contact. Parallel connection of up to 5 standard units and series connection of up to 2 units (some modifications required) are possible. The optional GP-IB programmer enables GP-IB control from a personal computer, etc.
