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,  
Primary Auxiliary Supply  
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.  
At 5.7V, PC can source up to 1.5mA. In the example shown in  
Figure 4, PC powers a module enabled LED.

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.

The PR pin supports paralleling for increased power with N+1
