EA-PS 10080-340 3U 10000W Programmable DC Power Supply

The EA-PS 10080-340 3U is a high-performance programmable DC power supply from the EA Elektro Automatik PS 10000 Series, delivering up to 80V output voltage, 340A output current, and 10000W output power in a compact 3U form factor. Designed for demanding industrial and laboratory applications, it combines high efficiency (up to 94.5%) with advanced autoranging technology, enabling a wide operating range and reducing energy costs. This power supply features precise voltage and current regulation with load regulation of ≤0.05% FS for CV and ≤0.1% FS for CC, and ultra-low ripple of ≤10mV rms and ≤100mV pp. Built-in protections (OVP adjustable 0-110%, OCP adjustable 0-110%, OPP adjustable 0-110%, overtemperature) safeguard sensitive loads against overvoltage, overcurrent, and overheating. With integrated USB, Ethernet, and galvanically isolated analog interface, plus optional fieldbus modules (Profibus, CANopen, EtherCAT, RS232, ModBus TCP), it supports automated test systems, battery charger testing, fuel cell test systems, on-board charger test, and general laboratory use. Master-slave parallel operation via Share bus allows up to 64 units to be combined for higher power with true current sharing, while remote sensing compensates for voltage drops up to 5% of nominal voltage. The 3U chassis with forced air cooling (front intake, rear exhaust) ensures reliable operation at ambient temperatures up to 50°C.
