The SPS-M/A Series DC Power Supply System comprises two series cabinets: SPSM and SPSA, each offering different control modes. A single cabinet can provide a maximum output voltage of 2250V and a current of 3000A, with an output power of up to 180kW. By utilizing a master-slave configuration, the system’s output capacity can be increased to 576kW.

The SPSM series cabinets utilize world-famous circuit breakers to control the input of each power module. Upon powering on, a specified 3U or 6U height power supply is configured as the Master unit, enabling control over all the slave units. In the SPSA series cabinets, the CSP (Control & Supervisory Panel) acts as the Master, accompanied by a PDU (Power Distribution Unit). The PDU, housed in a 5U/8U height chassis, consolidates microprocessors and manages hundreds of thousand VA AC mains. The CSP displays the input and output parameters of the system. A touch panel interface provides users with an intuitive and comprehensive user interface, simplifying configuration, setup, and updates. Additionally, the system incorporates full protection designs to prevent potential injuries.

SPSA Series Advantage

● CSP5/CSP8* , connect with 5/10 units 3U height DC power supply or 2/5 units 6U height DC power supply.

● Built-in power meter, to monitor the AC mains parameters such as V, A, Frequency, Power and PF.

● Support efficiency calculation and electrical quantities recording.

● Built-in Timer, allows to set output running time.

● Easy to enable the output of each power supply from the touch screen, sequence On/Off DC power supplies.

● Display the output parameters of each DC power supply in the same system.

● PDU significantly simplifies the wiring for DC power system.

● User-defined AC input protection parameters such as OVP, UVP, OFP, UFP, OCP and Phase loss.

● Provide web GUI function to monitor & control the CSP via Ethernet.

* Even the same model CSP may be configured differently, which is based on the connected DC power supplies.
