The BK Precision PBZ20-20 is a bipolar type DC regulated power source that can continuously change both + and – polarities passing through 0 without changing the output terminal. It is capable of 4-quadrant operation, meaning that it is capable of both sourcing and sinking power, ideal for driving both inductive and capacitive loads. This power supply comes equipped with a built-in function generator, allowing for easy waveform and sequence generation. The output current of the BK Precision PBZ20-20 can be expanded among multiple units by using the synchronization feature. 

The switching + linear design of the BK Precision PBZ20-20 has allowed for a 40% reduction in weight while achieving extremely high-speed operation (CV mode: 100 kHz) and low ripple noise. The unipolar function is unique to the PBZ series power supply. “Unipolar mode” allows the PBZ20-20 to apply current in both directions (source and sink) while current flows in a single direction. Built-in measurement features allow for easy testing without the need for multimeters and other measurement devices. Furthermore, the measurement time TRIG signal allows the operator to program measurement start time and measurement delay time.
