6 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 SettingsError!
Reference source not found.” to verify and configure the limits.
