Troubleshooting Guide
Below are some frequently asked questions and answers. Please check
if any apply to your power supply before contacting B&K Precision.
General
Q: I cannot power up the power supply.
-
Check that the power cord is securely connected to the AC input
and there is live power from your electrical AC outlet.
-
Verify that the AC power coming from the mains contains the
correct voltage. The power supply can accept a specific range of
AC input voltages. Refer to section 2.1.
Q: How do I set up the supply to run in constant current mode?
-
The supply is a CV/CC power supply that automatically crosses over
from CV to CC upon a load which draws current at the current limit
(ISET). Therefore, it is dependent on the load. For example, if ISET
is configured as 1 A, the load must draw 1 A before the supply will
go into CC mode.
Q: How come my display voltage is lower than the voltage I set?
-
This is often because of the resistances from the test leads/wires
connected between the supply and the DUT (device under test),
which causes a drop in voltage. To minimize this drop, use remote
sense terminals to compensate and output a more accurate
voltage to the DUT.
Q: I cannot set voltage at the maximum rating.
-
This may be that the set voltage is outside of the voltage maximum
limit. Refer to section 3.6 under “Output Limit Settings” to verify
and configure the limits.
