PROGRAMMABLE POWER SUPPLY 2U

4000W Series: High Precision Series Programmable DC Power Supplies

APPLICATIONS

PPS Series 4000W is a switch-mode single output programmable DC Power Supply providing high power density in a 2U (3.5”  Height) stand-alone or rack-mount system.  It is a high-precision programmable DC source using 16 bit D/A & 24 bit A/D sampling circuits, and with voltage and current resolution of up to 0.1mV and 0.2mA respectively.  The unit allows Master/Slave Series/Parallel modes and multiple communication interfaces, which allows a more flexible and convenient use of the power supply.

These units are ideal for automatic test equipment (ATE) as well as electronic laboratories for testing any electronic industrial or medical equipment. Aditionally these power supplies can be used for burn-in of power supplies and DC-DC converters.
