PU500 48/28 48Vdc to 28Vdc 17.9A DC DC Converter

• Reliable Voltage Protection: Overvoltage protection (OVP) limits output to 15% above nominal, with external and remote sense capabilities to compensate for voltage drops up to 5%.
• Voltage Monitoring and Control: Over/under voltage alarm with customisable relay function (30 V, 0.5 A) and an inhibit input for remote start/shutdown using a 5–12V signal.

• Enhanced Redundancy and Surge Protection: Optional series diode output for parallel redundancy (10% derating for 24–48 V outputs) and inrush current limiting for smoother start-up (available on 110/220 inputs).
• Flexible Installation and Environmental Options: Includes train-standard input compatibility, conformal coating for 85% RH environments, and versatile mounting options like 19” rack sets, brackets, and empty boxes for modular configurations.
