EA-PSI 10500-20 2U Programmable DC Power Supply

The EA-PSI 10500-20 2U is a high-precision, programmable bench and system DC power supply offering 500V, 20A, and 3000W of output power (derated to 1500W when operating on 110-127V AC input). With an impressive efficiency of up to 95%, it delivers clean, stable power with low ripple (40mV RMS, 500mV P-P) and fast transient response (20ms voltage rise, 10ms current rise). Its advanced control features include a built-in function generator, master-slave parallel operation, and comprehensive remote control via analog, USB, Ethernet, and optional digital interfaces (CAN, Profibus, etc.). Housed in a compact 2U 19" rack-mountable chassis with a 5-inch color touchscreen, it is ideal for R&D, test benches, and automated test systems requiring reliable, programmable power.

Key Features

• High Power & Voltage: Delivers 0-500V, 0-20A, and up to 3000W (1500W derated) for demanding applications.
• High Efficiency & Low Ripple: Achieves up to 95% efficiency with minimal output noise (40mV RMS, 500mV P-P).
• Exceptional Regulation & Stability: Features precise load regulation (CV: ≤0.05%, CC: ≤0.1%, CP: ≤0.3%) and line regulation (≤0.01%).
• Fast Dynamic Response: Offers quick settling times (Voltage 10-90%: ≤20ms, Current 10-90%: ≤10ms).
• Comprehensive Safety & Isolation: Provides reinforced insulation (3750Vrms AC-DC) and high DC isolation (up to 2000V DC to PE).
• Advanced Programmability: Equipped with a built-in function generator (sine, ramp, arbitrary, PV/FC simulation) and supports master-slave parallel operation for power scaling.
• Versatile Control & Interfaces: Features a 5" color touchscreen HMI, analog interface (0-5V/10V), USB, Ethernet, and a slot for optional digital interface modules (CANopen, Profinet, ModBus TCP, etc.).
• Robust Construction: Designed in a 2U 19" rack-mount form factor with intelligent fan cooling for reliable operation in system integration.
