EA-PS 11500-60 4U 30kW Programmable DC Power Supply

The EA-PS 11500-60 4U is a high-performance, 30kW benchtop power supply designed for demanding industrial and laboratory applications, such as electric vehicle component testing and high-voltage industrial test. As part of the programmable PS 10000 4U Series, it delivers precise DC power with an output rating of 1500V and 60A. This unit excels as a versatile DC power source, supporting constant voltage (CV), constant current (CC), constant power (CP), and internal resistance (CR) regulation modes for comprehensive testing scenarios. Its robust design enables integration into scalable master-slave parallel systems, where up to 64 units can be combined to achieve a massive total power of up to 1920kW, facilitated by Share bus technology for dynamic voltage balancing.

Remote control and monitoring are seamlessly achieved via built-in USB and Ethernet ports, as well as a galvanically isolated analog interface (15-pin D-Sub), offering flexibility for automation. Comprehensive protection features including overvoltage protection (OVP), overcurrent protection (OCP), overpower protection (OPP), overtemperature protection (OT), and power fail (PF) detection ensure safe operation for both the device and the connected load. Additional advanced functionalities include series connection capability (with insulation checks), SEMI F47 compliance for ride-through during AC voltage sags, and convenient USB data logging that saves operational data in CSV format directly to a USB stick for analysis.
