Frequently Asked Questions

What are the acceptable operating temperatures?

The ambient temperature for operation ranges from 0 to 50 degrees Celsius.

How should high-voltage wiring be handled near the output connectors?

Use UL1330 equivalents for output leads, keep the length within 150mm, and avoid binding or fitting them near a shield.

What is the nominal output power and operating efficiency?

The nominal output power is 1.7W, with minimum efficiency stated at 65%.

Should I disconnect the power before handling the connectors (CN1/CN2)?

Yes, always turn off the inverter's power supply when putting in or taking out either connector.
