47-63Hz). A built-in current balancing circuit and OR-ing diodes allow configuration for hot-swap and parallel-redundant N+1 operation. These power supplies are designed to be used with Kepco's Series RA 19-4C rack adapters. The RA 19-4C rack adapter accepts up to four modules. All input/output connections are through a 24- pin connector that plugs in to the rack adapter. -

Page 7: Features
FEATURES DIP SWITCH CONFIGURATION The power supply incorporates one DIP switch, SW1 (see Figure 5), which must be configured before the unit is installed in the rack adapter. The DIP switches control the following parameters: • Position 1 - default: position 1 is OFF. When switch is ON, AUX 5V supply is made avail- able on pin 15 (used for I C communication). -
Page 8: Front Panel Access
FRONT PANEL ACCESS. The front panel provides a power ON/OFF switch controlling input power and a “VDC ON” indica- tor which lights green when the unit is operating. The indicator lights red if the unit fails or if RESET is pressed; it lights red for about 30 seconds if there is a power loss.. CAUTION: DO NOT repeatedly toggle the power ON/OFF switch as this may cause unit to fault. -
Page 9: Output Voltage Control
Rs (see Table 2) is measured across ± IMON pins (requires millivoltmeter, range 0 to 200mV). Accuracy is ±3%; contact Kepco if greater accuracy is required. There is no isolation between ±IMON, negative d-c output, /P_OK and RV signals. -

Page 11: Current Limit Setting And Excess Power Protection
3.7.2 CURRENT LIMIT SETTING AND EXCESS POWER PROTECTION The output characteristic of the power supply is square type, with default current limit at 105% of nominal current. If a current limit lower than the default is needed, a 0.5 to 4.5 kohm resistor can be installed on the main printed circuit board at location R9. -
Page 12: Retaining Latches
NOTE: Retaining latches must not be used to secure the HSF power supply in the rack adapter for shipping purposes. For shipping HSF units installed in the rack adapter, the units must be secured by two flat head #8 screws (Kepco P/N 101-0188): FLP0, 8-32 X 0.375, ST at the top of the rack adapter.
