EA-PS 10200-420 4U 30kW Programmable DC Power Supply

The EA-PS 10200-420 4U is a high-power, programmable DC power supply from the PS 10000 4U Series, delivering 30kW of power with a 200V, 420A output. It is engineered for demanding industrial applications such as high-voltage device testing, battery pack simulation, and as a versatile bench power supply. The unit offers precise control with multiple operating modes including constant voltage (CV), constant current (CC), constant power (CP), and internal resistance simulation (CR). For expanded system capabilities, it supports master-slave parallel operation, allowing up to 64 units to be combined for a total system power of up to 1920 kW. Comprehensive protection features ensure safety and device longevity, including configurable overvoltage (OVP), overcurrent (OCP), and overpower (OPP) shutdowns, along with overtemperature (OT) and AC undervoltage (Power Fail) protection. The built-in Share bus facilitates voltage balancing in parallel systems. Remote monitoring and control are enabled via standard USB and Ethernet ports, an isolated analog interface (0-5V/0-10V), and optional digital interface modules (CAN, Profibus, EtherCAT, etc.). Data can be recorded directly via the front-panel USB port for logging. The unit is designed for 19" rack installation and is available in standard air-cooled or optional water-cooled (WC) versions.
