Please contact factory for other shelf and power plant options. GENERAL FEATURES Hot Swappable Modules These shelf-mounted modules are easy and safe to install or remove while system is operational without affecting the overall system’s performance. Current Limit Upon reaching 110% of rated current, the rectifier will automatically limit the current down to short circuit conditions with no fold back. Parallel Operation and Automatic Load Sharing Forced share connection is made via a hard wire. Sharing is within ±10% of the average current for the load applied. Safety UL/CUL Approved: UL 1950/CSA 950. File Number: E131694 Remote Control Enable Signal The rectifier’s output voltage control may be changed from internal float and equalize pots to external remote control though a digital ground signal.

This alarm consists of a red LED and a flashing green OK LED. Conditions which may lead to an RFA are: Low Current - Output current has decreased to below 5% of its rated value. Unit Shutdown - Any shutdown occurrence due to overvoltage, external shutdown command, unacceptable ambient temperature conditions or low AC input voltage. Load Sharing Terminal Pin Out Of Range - The terminal pin is out of range. Remote Control Terminal Out Of Range - The remote control terminal pins are out of range. Line Sag - This condition occurs when the nominal voltage decreases below 180V. Normal range is 208240V. Fan Malfunction - The fan has stopped operating or is not providing the airflow needed to cool the unit. Over Temperature - The ambient temperature has exceeded 65°C. www.murata-ps.com High Voltage Shutdown (HVSD) The unit’s built-in high voltage limit is permanently set at 60V. When internal shutdown occurs, the unit may be restarted by a local switch or by a remote signal. Surge Protection The unit will withstand lightning and input surges of 6000V/3000A. Under Voltage Protection When input voltage is below 105 VAC, the rectifier’s operation is automatically power limited.
