ADJUSTMENT OF THE OVERVOLTAGE PROTECTION (OVP)
To adjust the OVP the sense lines must be connected over a 100
Ω / 10
Watt Re-
sistor and the over voltage protection measured directly on the output voltage
connector.
Adjust the OVP using the external pot on the front panel of the Power Supply,
named OVP
adj
.
Here the OVP = 30V.
ADJUSTMENT OF THE OUTPUT VOLTAGE (Vout)
With parallel operation, each output voltage must be adjusted as closely as possi-
ble to the same value, due to the equal current distribution in the units.
Connect the +Sense (Pin G) to the +UA (Pin A) and the -Sense (Pin E) to the -UA
(Pin C) on the Burndy Connector located on the rear panel power supply.
Adjust the output voltage using the external pot on the front panel of the Power
Supply, named V
adj
.
Here the UA = 26V.
Replace the power module that you removed previously and remove the module
that has been adjusted. Repeat the steps listed above on the second module that
is now present in the unit.
➪
Do not shorten the sense lines, as this may cause damage to the power sup-
ply.
➪
This adjustment is normally not required as the unit has already been cor-
rectly set by the manufacturer.
