EA-PS 9750-06 1U Programmable DC Power Supply

The EA-PS 9750-06 1U is a high-performance programmable DC power supply from EA Elektro-Automatik, designed for laboratory, R&D, and industrial applications requiring very high voltage. It delivers up to 1500 W of power with an extensive output voltage range of 0...750 V and a current up to 6 A. This 1U high, 19-inch rack-mount unit features a flexible autoranging output stage, allowing for optimal power delivery—higher voltage at lower current or higher current at lower voltage—always constrained by the set power limit. With an exceptional efficiency of up to 95% and active Power Factor Correction (PFC), it operates efficiently on a wide AC input range of 100...264 V, making it suitable for global use. The power supply includes comprehensive protection circuits such as overvoltage (OVP), overcurrent (OCP), overpower (OPP), and overtemperature (OTP) protection to ensure operational safety. It offers versatile remote control via galvanically isolated digital interfaces (USB and Ethernet) using SCPI commands or ModBus RTU protocol, as well as an analog interface for setting and monitoring parameters. Additional features include remote sensing, a share bus for parallel operation, a built-in discharge circuit for safe shutdown (reducing voltage below 60 V DC), and temperature-controlled fans for effective cooling. Ideal for high-voltage electronic testing, prototype development, and workshop environments.
