ELEKTRO-AUTOMATIK Bi-directional DC Power Supply, 1500V, 60A, EA-PSB-11500-60

The EA‑PSB‑11500‑60, available at Avalon Test Equipment, is engineered for demanding testing of high-voltage battery systems, electric vehicle components, power electronics, and photovoltaic modules. With autoranging across voltage and current ranges, it supports constant voltage (CV), constant current (CC), constant power (CP), and constant resistance (CR) modes. The device delivers seamless transitions between sourcing and sinking power, enabling energy feedback into the grid or adjacent units, thereby improving energy efficiency and minimizing thermal loads.

Its advanced functionality includes programmable function generation, multi-unit synchronization, and comprehensive safety protections (OVP/OCP/OPP/thermal). Equipped with galvanically isolated communication interfaces—including USB, analog I/O, CAN, LAN, Modbus, Profibus, and DeviceNet—it integrates easily into automated test benches. Featuring intuitive front-panel touchscreen control and optional water cooling, the EA‑PSB‑11500‑60 is a highly capable and scalable solution for advanced power testing environments.
