4 FAQs about [Dry contacts of high frequency inverter]

Are dry contacts good for inverters?

So Dry Contacts are ideal. However... The problem is that the dry contacts are not designed for this; they were originally designed for a battery low warning. They can with some models be used to tell when the inverter is in battery mode (so you can operate an AC-out neutral to earth relay; setting 38).

What is the difference between dry contact switch on and alarm04?

Dry contact switch on (25V) and alarm04 at BACK TO GRID LEVEL. During charging the contact switched to open at BACK TO Battery (25.5V) which is 0.5V higher. Then alarm04 goes away at 1V above back to grid (26V). My cut out is set at 24V. Thus alarm04 goes away 2V higher than cut out.

What's the best way to wire a dry contact light?

For the actual dry contact connection, I'd use a small 3 V or 5 V plugpack, an LED light (preferably an industrial type with a decent bezel and diffuser) and a current limiting resistor. Wire them all in series, with care for the polarity of the LED and plugpack.

Which EV traction inverter is best?

For EV traction inverter, more efficiency and right performance are key. While IGBT is ideal for cost-optimized drive-train, SiC demonstrates higher efficiency under WLTP partial load scenario. Infineon offers the best scalability in market between IGBT and SiC, allowing customers to freely choose the technology for their needs,
