Lucent Technologies DC-DC Converter and Shelf Assembly
• High Voltage And Low Voltage Alarms: the high and low
voltage detection circuits monitor the output voltage and
provide an indication to the major and minor alarm circuits
when the thresholds are exceeded.
• High Voltage Shutdown: the high voltage shutdown circuit
protects the modules and the connected load from high
voltage surges by automatically shutting down the converter
when the voltage exceeds 58.0 + 0.5 volts.
• Restart Circuit: the restart circuit attempts to restart a failed
converter after a high voltage shutdown. If the high voltage
condition has ceased within the time limit (approximately
3-5 seconds), the converter will restart. If the high voltage
condition is still present, the converter will lock out.
• Major and Minor Alarm: the converter shelf assembly has
two Form "C" contacts, one for converter major and one for
converter minor. When one converter fails, the converter
minor relay will operate and when two converters fail, the
converter major relay will operate.
