EA-PS 9750-12 1U Programmable DC Power Supply

The EA-PS 9750-12 1U is a high-performance 3000W programmable DC power supply from the EA-PS 9000 1U series, engineered for demanding laboratory, R&D, and industrial applications requiring very high voltage. It delivers an extensive output voltage range of 0...750 V and a substantial output current of up to 12 A. Encased in a compact 1U high, 19-inch rack-mount chassis, this unit incorporates a flexible autoranging output stage, ensuring optimal power delivery—providing higher voltage at lower current or higher current at lower voltage—all within the 3000W power limit. With an efficiency of up to 93% and active Power Factor Correction (PFC), it operates on an AC input range of 180...264 V. The power supply is fortified with comprehensive protection features including Overvoltage (OVP), Overcurrent (OCP), Overpower (OPP), and Overtemperature (OTP) protection. For versatile integration into automated systems, it offers remote control via galvanically isolated digital interfaces (USB and Ethernet) supporting SCPI commands and ModBus RTU protocol, alongside a galvanically isolated analog interface. Key additional functionalities include remote sensing, a share bus for seamless parallel operation to scale power output, a built-in discharge circuit for safe shutdown (reducing voltage below 60 V DC), and temperature-controlled fans for effective and reliable cooling. This makes it an ideal solution for high-voltage electronic testing, automated test benches, and industrial power applications.
