EA-PS 10750-12 2U 3000W Programmable DC Power Supply

The EA-PS 10750-12 2U is a high-precision, rack-mountable programmable DC power supply from the EA-PS 10000 series, designed for demanding industrial test systems and laboratory applications. It delivers 0–750V with a current range of 0–12A, offering a maximum power output of 3000W (derated to 1500W when operating on 110–127V AC input). Featuring a 5-inch color TFT touchscreen (HMI), two rotary knobs with push-button functionality, and comprehensive remote control interfaces (USB, Ethernet, analog, and optional digital modules), this unit provides exceptional flexibility and control. With built-in master-slave and Share bus capabilities, up to 64 units can be paralleled to create systems with up to 192kW total power. Advanced regulation modes include constant voltage (CV), constant current (CC), constant power (CP), and internal resistance simulation (CR). Comprehensive safety protections (OVP, OCP, OPP, OT, PF) and high efficiency (≤95% at full load) ensure reliable and safe operation in test, burn-in, battery charging, and electronic load simulation applications.

Key Features

• Wide Voltage & High Power Range: 0–750V, 0–12A, 3000W max output (1500W on 110–127V AC).
• Multiple Regulation Modes: Constant Voltage (CV), Constant Current (CC), Constant Power (CP), and Internal Resistance (CR) modes for versatile testing scenarios.
• Advanced Control & Interface: 5-inch capacitive touchscreen, rotary encoders, USB host (front) for logging, USB/ Ethernet/ analog remote control, and optional interface modules (CAN, Profibus, Profinet, ModBus TCP, EtherCAT, RS232).
• Scalable Parallel Operation: Master-slave and Share bus support for paralleling up to 64 units (192kW total) with automatic current sharing and system control via a single master unit.
• Comprehensive Safety Protections: Configurable overvoltage (OVP), overcurrent (OCP), overpower (OPP), overtemperature (OT), and power fail (PF) protections with visual/audible alarms and automatic output shutdown.
• High Precision & Stability: Excellent line/load regulation (CV: ≤0.01% FS, CC: ≤0.1% FS), low ripple (50mV RMS, 500mV pp), and accurate display (voltage ≤0.05% FS, current ≤0.1% FS).
• Robust Industrial Design: 19-inch, 2U rack-mount enclosure with forced-air cooling (front-to-rear), IP20 protection, and operation up to 50°C ambient temperature.
