3 Power Supply Unit (PSU)

3.1 Description

This rectifier units are rated at full load when operated from high line. For Low operation, the output is derated to half load. This derating is automatically activated from the Alarm Control Unit (ALU). However, the rectifier can operate on a stand-alone basis, if this ALU is removed or nonfunctional.

Warning: In the absence of the ALU, the automatic derating of the rectifiers at Low Line is not effective. Exceeding the 50% load limit at Low Line may damage the rectifiers.

The modular design provides the flexibility to configure and expand the system as the load demand increases. Each rectifier unit is swappable with front access for ease of maintenance without system shutdown, providing uninterrupted service.

The rectifier unit has an active power factor correction of greater than 0.99 for maximum AC utilization. Each module is equipped with an AC switch located at the front of the module. Figure 3 shows a front view of PSU.

Note: The equipment is only for installation in a Restricted Access Location.

The equipment is used on a stationary equipment/unit only.
