7.5 AMP MODULAR SWITCH MODE RECTIFIER
RM487.5
FEATURES
* SWITCH MODE * >.99 PFC * >84% EFFICIENCY * AUTOMATIC LOAD SHARING * HOT-SWAP CAPABLE * COMPACT SIZE * SHELF MOUNTED * SOFT START TURN-ON!
DESCRIPTION
The RM487.5 Modular Switch-Mode Rectifier is one of C&D Technologies' family of rectifiers that may be used in modular power plants. This unit will function in parallel with any rectifier with similar current sharing capacities. This compact, versatile and efficient unit is ideal for use in advanced telecommunications applications. Its small size allows the user to plan economically for system expansion at minimum cost and makes it ideal for use in fiber optic, microwave and other applications where space is at a premium.

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 Forced share connection is made via a hard wire. Sharing is within 10% of the average current for the load applied. 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. Current Limit Upon reaching 110% of rated current, the rectifier will automatically limit the current down to short circuit conditions with no fold back. Safety UL/CUL Approved: UL 1950/CSA 950.

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 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 65C. 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.
