Efficiency 91% Typical
6.3. Controls and Indicators
Rectifiers
Input Healthy LED AC power present.
Output Healthy LED DC output voltage within operating range (-39.5
to –59.5 VDC).
Output Current LED On when rectifier is supplying current.
Thermal Control LED On when one of three internal sensors is above
90ºC
Current Limit LED On when rectifier is in current limit.
.
Overvolts LED On when rectifier is above 57 Volts. (Must be
powered down to reset)
Overtemp LED On when one of three internal sensors is above
130ºC. Power Conversion is inhibited.
Fan fail LED On when Fan is running too slow.
Standby LED On when the unit is in the standby mode. No
output power is produced. Rectifier is still
active
+V Test Point Rectifier Voltage can be measured with a
voltmeter between COM and +V.
COM Test Point Negative reference for both +V and +I
+I Test Point Rectifier Current can be measured with a
voltmeter between COM and +I.
Float / Boost/Equalize Switch Used to Control voltage on systems without a
PSCU
Float Trim Pot The float pot is used to adjust the default float
