FUNCTION
1
Frame Ground (earth)
Connect to earth ground. This terminal is connected to the case.
2
A-C Input (L, N)
Connect to AC: 100 to 120V AC or 200 to 240V AC input line.
3
DC Output (+, –)
Connect to load (see Figure 8).
4
Sense (+S, –S)
Used to compensate for voltage drop in the connecting lines from the output ter-
minal to a load; they are connected to ± DC Output terminals for local sensing
(see Figure 8).
5
Output Voltage Reference (REF)
Using REF terminal (together with the RV terminal) allows all the output voltages
of slave power supplies to be controlled by one voltage adjustment of a master
power supply (normally connected to the RV terminal with a metal shorting link).
6
Output Voltage Adjust (RV)
This terminal (together with the REF terminal) is used for remotely controlling
output voltage (see PAR. 3.2).
7
Current Balance (CB)
This terminal is used when several power supplies are connected in parallel (see
PAR. 5.3).
8
Power Failure (PF)
These terminals output an open logic signal if output voltage drops to 80 % or
lower of a set voltage, or if output voltage is shut down due to overvoltage or
overcurrent protection, fan speed failure, or overheating. (see Figure 6).
9
Remote ON-OFF (+RC, –RC)
Output is turned ON-OFF by shorting-opening the RC terminals (output OFF
when open). RC terminals are isolated from input and output terminals. Nor-
mally, ±RC terminals are shorted with a metal shorting link (see PAR. 3.3).
10
Output Voltage Trim Adjust (Vadj)
Adjusts output voltage.
11
Output Voltage On indicator
(green)
Green LED lights when output voltage is present.
NOTE Unit is shipped with shorting links
(not shown) connecting +RC to –RC (see
PAR. 3.3) and REF to RV (see PAR. 3.2)
installed and with local sensing cable
installed (connects +DC Output to +S and
–DC Output to –S) (see PAR. 5.2
