PSP Series High Precision Programmable Switching Mode DC Power Supply

PSP series is high precision programmable DC power supply new generation design adopted & Advanced technology, it has outstanding with-load transient response speed, super low ripple and high power density, also is support multi-units parallel connection working, different power models all use the same enclosure.

This series is ideal option for products research, qualification, manufacturing burn-in, medical filed, environment field, energy & electric field, ATE test and other filed need high-power DC power supply.

1. High efficiency, power-saving, environmental and low emission.

2. High reliability & stability

3. Super low ripple @ 20mVrms

4. Low noise @100mVp-p,20Hz~20MHz

5. 1ms quick load response, u00b10.75% fluctuation

6. Quick load response: Meet requirement of quick load or current variance, load response time<1ms, voltage fluctuation
7. Various control modes:

8. 10-turn potentiometer/0~5V or 0~10V analog signal (isolated / non-isolated)

9. Programmable, different communication port: RS232, RS485, CAN, USB, GPIB, LAN etc.

Master-slave control

10. Support multi-units parallel connection working, total power could be added up to 150KW

11. Short/over heat/over voltage/lack phase protections

12. Module assembly, easy for installation or maintenance.

13. High power density: Power density is greatly improved by modular design; enclosure of 15KW unit is only 3U standard industry enclosure, which is more convenient for parallel operation & system configuration.

14. Voltage compensation function: Connects to load directly to compensate voltage loss on load cable
