Plug-in power supply module for redundancy
The 1112PSM is a plug-in power supply module for use with the 1112PS rack-mount power supply. Each module is capable of delivering up to 37 amps of 12V DC power. Two 1112PSM modules can be used in one 1112PS for redundant operation. When used in this configuration, both supplies share the load placed on the unit. If any of the modules fails, the load is transferred to the remaining good supply and a fault indication is displayed.
Each 1112PSM contains a built-in cooling fan with internal speed control for optimal cooling. Fan operation is monitored and a fault is reported in the event of a fan failure. Three status LEDs are located on the rear of the module to provide visual indication of AC input, DC output, and fault status.
