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. Parallel Operation and Automatic Load Sharing A series of RM4830 rectifiers will automatically share equal amounts of the load current when operating in parallel within 5% of the average current for the load applied. N+1 Operation The rectifier can operate in true N + 1 redundacy mode. Remote Equalize The rectifier output may be changed from float to equalize via remote signal. Current Limit When rectifier current reaches 30ADC - 32ADC, the unit will automatically limit the current down to short circuit conditions with no fold back. LED Indicators The front panel includes a 10 segment yellow LED output current bar graph, a green normal operation LED, and a red rectifier failed LED. Safety UL/CUL Recognized: UL 1950/CSA 950. File No.: E131694 EMI filtering to FCC and VDE-0875 limits.

PROTECTION, ALARM AND CONTROL SYSTEMS
Rectifier Failure Alarm (RFA) Problems occurring because of an unacceptable relationship between the output power and load conditions will cause a Rectifier Failure Alarm (RFA). This alarm consists of a red LED. Conditions which may lead to an RFA are: Low Current - Output current has decreased to below 2% of its rated value. Unit Shutdown - Any shutdown occurrence due to overvoltage, external shutdown command, unacceptable ambient temperature conditions or low AC input voltage. 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 50C. High Voltage Shutdown (HVSD) The unit's built-in high voltage limit is permanently set at 60.5VDC. 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 106 VAC (with tolerance), the rectifier's operation is automatically inhibited. Output Circuit Protection Device (Fuse) The unit has one internal output protection fuse which is in series with the -48VDC output.
