PWS 1.8kW Rack 30V 60V 100V 300V 600V 1000V Programmable Adjustable 1800W Switching DC Power Supply

The PWS Series Programmable Switching DC Power supply cover large range of outputs, rated power from 1.8kW, 3.6kW, 6kW, 12kW, 15kW up to 100kW. The switching DC power supply 1800W are compact size switch mode programmable DC power supplies, only half 1U 19-inch rack mount size, with RS232 RS485 interface, supporting ModBus-RTU commands. The adjustable dc power supply 1800W provides options of remote sense function and analog remote control interface for output control and feedback. Reverse polarity switch is also available to allow the 1800W switching DC power supply to change output polarities in reverse direction. And the reverse current protection protects the programmable switching DC power supply 1800W against reverse current from DUT into the switching DC power supply itself. The 1800W DC power supply are available with different output ratings: 30V 60A, 60V 30A, 100V 18A, 600V 3A, 1000V 1A.
