DLS Series Troubleshooting: Navigating Solutions for IOTA's DLS Products

September 12, 2023 Matt Pang

Are you encountering power issues with your DLS Series Power Converter? We understand how crucial it is to maintain uninterrupted power, and we're here to help you troubleshoot and resolve these issues.

Step 1 - If the DLS is not providing power to the system or is not charging the batteries.

Using a voltmeter, verify that the electrical box or outlet is supplying 110-120VAC.*    

*216-264VAC for 240V DLS models

Step 2 - Check the DC output of the DLS.

Note: Always follow proper procedure when disconnecting the DLS from the battery.

1) Unplug the AC power cord of the DLS from the AC outlet.

2) Disconnect the Positive battery cable from the DLS unit.        

CAUTION: Do not allow the disconnected cable end to contact the chassis ground.

3) After the Positive battery cable is disconnected, reconnect AC power by plugging the DLS power cord into the AC outlet.

4) Measure the DC voltage between the DLS output terminals. Make sure the Dual Voltage Plug is not inserted into the Dual Voltage Jack before measuring.

If the power output is surging or inconsistent...

Step 1 - Verify that the airflow to and from the converter is not restricted by checking that the fan and vents are not blocked. The unit should be installed in a location that provides proper ventilation. The fan requires a minimum of four inches clearance.  Also, verify that no other objects in the area are obstructing the fans and vents.

Step 2 - Verify that the fan is operating. If the converter is warm to the touch, the fan should be running. If so, disconnect the AC power by unplugging the DLS. Allow the  converter to cool, then re-test. If the DLS is warm and the fan is not running, then the DLS is not performing properly and will need to be replaced.
