b) Thermal Power Limiting: Each rectifier continuously monitors the ambient temperature surrounding the power conversion
circuit. If this temperature for any reason (such as a high ambient temperature) increases above approximately +45°C
(+113°F), the Rectifier will not shut down. Rather, the rectifier will limit its maximum output power to maintain the temperature
of the power conversion circuit within design parameters. Operation between +45°C (+113°F) and +65°C (149°F) will result in
the output power being decreased. Full power capability is restored when the temperature decreases to below approximately
+45°C (+113°F). Figure 2.4 illustrates typical operating parameters.
WARNING! The module is rated for continuous operation at full output power up to +45°C (+113°F). Operation between
+45°C (+113°F) and +65°C (149°F) will result in output power decreasing. Operation above +65°C (+149°F) is considered
abnormal and should be used on a temporary
1
basis only.

Temporary Operation at Abnormal Temperature: Temporary operation refers to a period of not more than eight
consecutive hours per day, and a total of not more than 15 days in a year. (This refers to a total of 120 hours in any given
year, but no more than 15 occurrences in that one year period.)

c) Output Fusing: Output fusing is provided in each Rectifier. If a fuse opens, local and remote Rectifier Fail Alarms activate.
This fusing is not customer replaceable.
d) High Voltage Shutdown (Each Rectifier):
1. Selective: If rectifier output voltage exceeds an adjustable preset value and is delivering more than 10% of its rated
current, the rectifier shuts down.
After approximately 6 seconds, the rectifier automatically restarts. If rectifier output voltage again exceeds the high
voltage shutdown value within 5 minutes, the rectifier shuts down and locks out. Manual restart is then required (by
turning AC power off or removing the rectifier, then reapplying AC power or reinserting the rectifier). If the rectifier does
not experience a high voltage condition within the 5 minute time period, the restart circuit is reset.
Only the rectifier causing the high voltage condition shuts down.
Setpoint is adjustable from 56.00 to 59.50 volts DC. Factory set at 57.50 volts, unless otherwise specified. One
adjustment at the system MCA changes the setting of all Rectifiers.
