Installation and Operation Instructions
rev. 01/23/13
PROBLEMS:
No voltage on output
Voltage on output is reading low or high
POSSIBLE SOLUTIONS:
- Verify that input voltage is correct
- If the unit has a replaceable glass fuse, check it for continuity. If a
replacement fuse is needed, replace it wth a 4.0 A fuse.
*Loading higher value fuses may cause damage and void
warranty
- If the unit has a resettable fuse and the fuse is tripped, it may
be an output short circuit or overload. Remove input power and
determine the problem. When the problem is corrected, reapply
power to the unit.
- Verify that input voltage is correct
- Verify that the “Output Adjust” trim potentiometer is set correctly
using the “Voltage Output Adjustment” procedure shown below
- Check wiring for proper termination
VC3000
series voltage converters have an adjustable output of 1.2 to 24 VDC. Adjust output to a custom
voltage as follows:
1. Using a voltmeter, connect the positive lead to the “+” and the negative lead to the “-” of the terminal block
labeled “VDC”.
2. With a small, straight bladed screwdriver, adjust the “Output Adjust” trim potentiometer (located next to the
“VDC” terminal block) until the voltmeter reads the desired output.
3. Disconnect the voltmeter
4. Connect the load.
5. If exact output voltage is required, measure the voltage out under load and adjust accordingly.
