PMC-A

4.6.1

Functions during Master-Slave Parallel Opera-    
tion

The functions of the PMC-A during master-slave parallel oper-        
ation are as follows.

■

Voltmeter and Ammeter

For the total output current, sum the currents of the master and           
slave units.

■

Remote Sensing

Available only on the master unit.

■

External Control

Available only on the master unit.

■

External Monitoring

• External monitoring of output voltage (V MON)

 Can be monitored on the master unit.

• External monitoring of output current (I MON)

The output current of each master and slave units can be          
monitored. For the total output current, sum the monitor val-         
ues of the master and slave units.

• Status monitors

The status of the constant voltage operation (CV STATUS),        
constant  current  operation  (CC  STATUS),  output  on,  and       
POWER  switch  on  can  be  monitored  on  each  master  and         
slave units. 

・

Do not connect the common wires of the master and         
slave monitors o

u

tside  of  the  PMC-A.  If  the  wire        

connecting the load comes loose, the common wire       
will break.
