rack-mounted power systems

The AFE1200 power module is a rack mountable single phase AC to DC power

supply, designed to be a cost-competitive front-end power supply for distributed

power systems. It is particularly suitable for use in data processing, datacom and

telecom applications. The outputs are fully floating, enabling users to adopt whatever

rail reference configuration they require. The AFE1200 power modules are designed

for hot-swap operation and can be mounted into AFS2400/4800 power shelves for

redundant-mode operation.
