125VDC sequencing signals to modules on the RX7i backplane. The Power Supply Module plugs directly into slot 0 in the RX7i main rack. The power supply output can ride through the loss of up to one AC input line cycle without loss of output power. Protection is provided for overcurrent, overtemperature, and overvoltage fault conditions. IC698PSA100: Provides up to 100 W total output power at ambient temperatures of 0 to 60ºC without forced air cooling. Output voltages: +5 VDC output up to 20 amps +12 VDC output up to 2 amps –12 VDC output up to 1 amp IC698PSA350: Provides up to 350 W total output power; requires forced air cooling, provided by a fan tray mounted on the bottom of the rack. Output voltages: +5 VDC output up to 60 amps +12 VDC output up to 12 amps –12 VDC output up to 4 amps Features Operation from 85 to 264 VAC, 100 to 150 VDC Slide-in rack mount construction Electronic short circuit overcurrent protection Overcurrent and overvoltage fault protection Power factor correction for AC operation * indicates a trademark of GE Intelligent Platforms, Inc. and/or its affiliates.

Release History Version Date Comments PSA100E/PSA350E Aug 2010 Label change only. No change in functionality, performance or compatibility. PSA100D/PSA350D Aug 2006 Power supplies qualified to the Explosive Atmospheres Directive, European Safety for Hazardous Locations, Equipment Group II, Category 3 (ATEX) agency standard. Corrected an infrequently observed issue with power supply shutdown causing corrupted memory faults in CPU. PSA100C/PSA350C Jun 2005 Overtemperature detection. See GFK-2237C for details. PSA100B/PSA350B May 2004 See GFK-2237B for details. PSA100A/PSA350A May 2003 Initial release. Power Supply Operation On/Off Switch The two position On/Off switch, located on the front faceplate, is a logic level switch that enables or disables the output channels only. This switch does not interrupt the AC line input. Warning Lethal voltages are present inside the module whenever input power is present. VMEbus Power Monitor Interface Timing ACFAIL# The ACFAIL# signal is pulled down when the power supply inputs are no longer being provided or when the ON/OFF switch is OFF. The ACFAIL# signal is asserted at least 5ms before outputs fall below their specified limits to provide sufficient warning to the system of power failure. SYSRESET# The RX7i power supplies do not drive the SYSRESET# signal on the VME backplane. The RX7i CPU module controls the SYSRESET# signal. Indicators The following LED indicators are provided on the power supply front panel. LED Name Color Function FIELD OK green Turns ON when AC power is applied within its specification range. OUTPUT OK green Turns ON when all three DC outputs channels are operating within their specifications. Turns OFF if any of the three DC output channels has failed. OVER TEMP IC698PSA350 only red Turns ON if the critical supply temperature is exceeded or if the airflow sensor detects cessation of air flow. RX7i Power Supplies 3 GFK-2237F Overvoltage Protection Any output channel that exceeds the nominal output voltage by 15% or more will cause all outputs to latch off. The ON/OFF control switch or the AC input power must be recycled to reset Replaceable fuses are present on both the hot and neutral AC inputs. IC698PSA100 uses 4 Amp/250 Volt fuses. IC698PSA350 uses 8 Amp/250 Volt fuses. Note that the “A” version of the power supplies used 0.25” x 1.25” fuses. The “B” and later versions use 5 x 20mm fuses. Overcurrent/Short Circuit Protection All outputs are protected against overcurrent and short circuit with automatic recovery upon removal of fault. An electronic current limit is provided on each of the
