Manufactures description below:

The XLN series of programmable DC power supplies delivers up to 1560 watts of clean power on a single output. The compact 1U high 19 inch wide supplies were designed to meet the needs of both system integrators and benchtop users. Fast average command processing times of less than 50 ms, combined with the flexibility of industry-standard GPIB, LAN, USB & RS485 interfaces make these supplies ideal for ATE applications. Benchtop users will benefit from the built-in voltage and current meters displaying setting and output values concurrently, an intuitive user interface with full keypad and rotary knob as well as cost effective USB & RS485 interfaces that come standard with all models.

The XLN series is perfectly suited for ATE systems integration, product design and development, product QC and burn-in testing, production, electro-plating and other applications requiring high, reliable power.
