Four-Quadrant DC Power Supplies

← Shop All DC Power Supplies

Four-quadrant DC power supplies control both positive and negative voltage and current, providing source and sink operation with either voltage polarity. Often called bipolar power supplies, they support testing that requires controlled polarity changes and bidirectional current.

Explore Telonic’s four-quadrant DC power supplies for research, development and component testing. Compare voltage and current ranges, source and sink capabilities, response speed and programming options to find a supply suited to your application.

Why Choose a Four-Quadrant DC Supply?

Bipolar Output: Apply positive and negative voltage without manually reversing the output connections.

Source and Sink Control: Supply or absorb power across all four operating quadrants.

Dynamic Testing: Compare waveform and response capabilities for changing test conditions.

Core Applications

Electromagnet and Coil Testing: Control current magnitude and direction to investigate magnetic behaviour.

Motor and Actuator Development: Test devices requiring polarity changes and energy absorption.

Component Characterisation: Measure behaviour under positive and negative electrical excitation.
