Home Forums General Discussion Technical Questions GAL operator on Otis 211

As far as design goes, I wouldn't recommend an MOVFE to replace a black belt. GAL now has a direct replacement for the Otis black belt, which is based on their MONXT model, called OMNI. It's a direct drop-in replacement, and unlike the MOVFE, the power supply is not particular about voltages as long as it's 110-240vac.
