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

The EA-PS 11500-60 4U is a high-performance, 30kW programmable DC power supply from the PS 10000 4U Series, designed for demanding applications like high-voltage industrial test and electric vehicle component testing. It delivers a precise 60V DC output with up to 500A of current. The unit operates in multiple modes including constant voltage (CV), constant current (CC), constant power (CP), and internal resistance (CR), providing versatile control for complex testing scenarios. It features comprehensive protection with adjustable overvoltage (OVP, 0-110% Unom), overcurrent (OCP), overpower (OPP), and overtemperature (OT) protection, alongside power fail (PF) monitoring. For control and integration, it offers built-in remote control via USB, Ethernet (100 MBit), and a galvanically isolated 15-pin analog interface (0-5V/0-10V switchable), with optional plug-in modules for CANopen, Profibus, Profinet, ModBus TCP, and EtherCAT. A standout feature is the master-slave parallel system, allowing up to 64 units to be combined into a single, synchronized system with a maximum total power of 1920kW, utilizing Share bus for dynamic voltage balancing. Additional capabilities include series connection of identical models (with insulation checks), compliance with the SEMI F47 standard for ride-through during voltage sags, and USB data logging to CSV format files (max 4GB). The device boasts high accuracy (display: voltage ≤0.05% FS, current ≤0.1% FS), fast dynamic response (CV rise/fall time ≤10ms), and is available in standard air-cooled or optional water-cooled (WC) versions.
