AC Power Module
The AC power module is a single-slot module designed for the RM16M VAC-R Data Shelf.
The RM16M VAC-R Data Shelf can hold up to two power modules. When two power supply
modules are used, any loss of supply or operating voltage to one module causes the other module
to carry the entire load. If this happens, the common alarm contacts close to reflect the alarm
condition.
The AC power module consists of:
•
An AC-to-AC switching regulator
•
A green Power light on the front panel
•
An interface connector on the back of the module
