Bi-Directional DC Power Supplies

← Shop All DC Power Supplies
Bi-directional DC power supplies combine power sourcing and sinking in one instrument, allowing current to flow to and from the device under test. They suit applications where equipment both consumes and returns electrical energy, including battery testing and power conversion.

Explore Telonic’s range of bi-directional DC power supplies below. Compare voltage, source and sink current, power ratings and control interfaces. Regenerative models return absorbed energy to the mains, helping reduce heat generation during discharge testing.

Why Choose a Bi-Directional DC Supply?

Source and Sink: Supply power to your device and absorb energy returned during testing.
Integrated Testing: Combine DC supply and electronic load functions in one instrument.
Energy Recovery: Choose regenerative models to return absorbed power to the mains.

Core Applications

Battery Testing: Controlled charging and discharging within the supply’s operating limits.
DC-DC Converter Testing: Evaluate converters designed for power flow in both directions.
Energy Storage Development: Test systems that alternate between supplying and absorbing power.
