Output Connections and Considerations
Remote-Sense leads must be protected for conditions such as
lead reversal, noise pickup, open circuit or excessive output lead
resistance between the sense point and the converters output
terminals. For applications that may draw more than the rated
current, a fast-acting electronic circuit breaker must be utilized
to protect the converter. Under no circumstance should the rated
current be exceeded. Utilizing or testing of current limit or short
circuit current will damage the converter. Ensure that the total
output capacitance connected to the converter does not exceed
the limits on Page 16, “Maximum Output Capacitance,” of
the design guide.
The permissible load current must never be exceeded during
normal, abnormal or test conditions. Converters subject to dynamic
loading exceeding 25% of rated current must be reviewed by
Vicor Applications Engineering to ensure that the converter will
operate properly.
Under dynamic-load, light-load, or no-load conditions, the
converter may emit audible noise. Converters that utilize remote
sense may require compensation circuitry to offset the phase
lag caused by the external output leads and load impedance.

375V Input
Primary Control – PC Pin
Module Enable/Disable
Module Alarm
The module may be disabled by pulling PC below 2.3V with respect
to the –Input. This may be done with an open collector transistor,
relay, or optocoupler. Multiple converters may be disabled
with a single transistor or relay either directly or via “OR’ing”
diodes. See Figure 2.
The module contains “watchdog” circuitry which monitors input
voltage, operating temperature and internal operating parameters.
In the event that any of these parameters are outside of their
allowable operating range, the module will shut down and PC will
go low. PC will periodically go high and the module will check
to see if the fault (as an example, overtemperature) has cleared.
If the fault has not been cleared, PC will go low again and the
cycle will restart. The SC pin will go low in the event of a fault
and return to its normal state after the fault has been cleared. See
Figures 3 and 5.
Primary Auxiliary Supply
At 5.7V, PC can source up to 1.5mA. In the example shown in

375V Input
Compatible interface architectures include the following:
Secondary Control – SC Pin
AC-coupled single-wire interface. All PR pins are connected to a
single communication bus through 0.001µF (500V) capacitors. This
interface supports current sharing and is fault tolerant except for
the communication bus. Up to three converters may be paralleled
by this method. See Figure 9.
Output Voltage Programming
The output voltage of the converter can be adjusted or
programmed via fixed resistors, potentiometers or voltage
DACs. See Figure 8.
Transformer-coupled interface. For paralleling four or more
converters a transformer coupled interface is required, and under
certain conditions a PR buffer circuit.

reduced by the same percentage that output voltage is
trimmed down. Do not exceed maximum rated output current.
