Better Lighting. Better Energy. Better World

I just purchased a new transverter, model TPS‐0120. My electrician tested it before installing and it is reading 44 VDC. I thought my relays needed 28.5 VDC…isn’t that right? Is my new transverter faulty?

No, your unit is perfectly normal, but it is a good question. The replacement transverter models have been redesigned from the original units. They contain an automatic shut off feature to protect it from quickly failing if a stuck switch occurs. If a switch does stick and the transverter begins to overheat, it will shut down for a time to cool itself off and then restart again. This added feature among other design changes caused the output voltage to rise. It is common to get a voltage reading between 40‐44 VDC if testing without a load. This overall higher voltage is not a concern for the system. The relays (both original and new) will respond correctly and are not in danger from this voltage variance.
