26 Operation
UM5C06B / C ( 169-2071-500 ) P0711722 Standard 10.00 May 2001
AC inrush current
The AC current during the turn on sequence of the rectifier, under all input
and output conditions specified in this document, will not exceed its full load
steady-state value.
Sequential start
The rectifier Temporary Release (TR) leads are available for use with an
external sequential start circuit.
Parallel operation
The rectifier is capable of operating in parallel with other rectifiers having
similar output slope characteristics.
Discharge of output capacitors
The output capacitors will automatically discharge when the rectifier is
disconnected and the AC power has been removed.
Load sharing
Rectifiers connected in parallel and sensing at the same point will share the
load with other rectifiers having similar negative output slope characteristics
(300 mV drop from zero to full load).
The rectifier will share the load proportionally to its output rating to a
precision within +
10%.
Monitoring features
Input AC voltage monitor
The rectifier monitors the input voltage and inhibits its operation when the
voltage exceeds the specified limits. Refer to the “Summary of
Specifications” section, sub section Electric. An RFA is initiated.
The rectifier recovers its normal operation automatically when the specified
input voltage is re-established.
Thermal shutdown
The rectifier protects itself against thermal overstress by inhibiting its
operation for the duration of the high temperature condition. The RFA
alarm is triggered. The rectifier will restart after the temperature has returned
to a safe level.
