Programmable and Bidirectional DC Power: Experience Test Excellence

Chroma programmable DC Power Supplies cover a wide range of power, voltage and current with advanced features for lab or rack-mounted applications. Most models include a wider operating range with constant power, higher current ranges, precision readback of output current and voltage, output trigger signals, as well as the ability to create complex DC transients waveforms to test device behavior with voltage deviations. Our programmable DC power supplies are commonly used in DC-DC converter, PV inverter, telecom, battery charger, EV / automotive, burn-in, and plating/electrolysis testing.

We know you have a choice when selecting a variable DC Power Supply, but the advantage is clear with Chroma. We invest more in R&D than any other manufacturer, so you can be sure you are getting the most out of your lab’s equipment budget.

Advantages include:

  • REPEATABLE TURN-ON: Programmable Slew Rate allows the user to repeatably control the turn-on and eliminate/validate input related issues
  • WAVEFORM TRANSIENTS & SEQUENCING: Programmable Waveform Sequencing emulates complex transients providing control over each step slew rate and timing including 8 digital outputs (TTL)
  • HIGH ACCURACY READBACKS: Eliminates the need for external meters, shunts, relays/switching plus calibration
  • CONSTANT POWER OPERATING ENVELOPE: Replaces the need to purchase multiple units
