Kepco RA 19-1U Rack Adapter

The rear panel contains the fixed power and signal connections. The other side of the rear panel is an internal PCB back plate which has connectors which interface directly with the power and signal connectors of HSF Series power supplies, permitting hot swappable insertion and extraction. User-configurable keying ensures that only the correct power supply can be installed in a keyed slot.

The HSF Power Supplies each provide a normally closed (N.C.) and normally open (N.O.) line referenced to common (COM) for use as an alarm at the users discretion. The alarm circuit is independent from the power configuration (series, parallel or independent). The N.C. line opens upon failure, the N.O. line closes upon failure. The 300W, 600W, and 1200W/1500W modules also have a logic alarm signal (±PF) that performs the same function.

All mechanical and electrical specifications are contained in the mechanical outline drawings. The rack adapter is user-configurable for parallel, series, or independent power supply operation. Forced current sharing and OR'ing diodes for N+1 redundancy are built in to the HSF power supplies.

HSF 150W Series Power Modules and the RA 19-6B Rack Adapter have been tested and deemed compliant with the requirements for physical protection of Network Equipment-Building System (NEBS) for earthquake zone 4 per GR-63-CORE, including both damage resistance and functional performance requirements. This means that the power assembly suffered no physical damage as a result of the testing and provided full specified performance both during and after exposure to the test environment.
