SoftStartRV SSM6T Soft Start Marine Air Conditioner Compressor Soft Starter

The SoftStartRV SSM6T SoftStart Marine is a purpose-built marine air conditioner soft starter designed to work with any boat air conditioning system. By intelligently ramping up compressor startup power over approximately one second, it reduces startup current draw by up to 70%, eliminating the hard inrush surge that can overload generators, inverters, and battery banks.

Compatible with both 110V and 220V single-phase systems, the SSM6T is an ideal solution for boaters who want to run their AC on a small generator, shore power with limited amperage, or stored battery power. Its waterproof enclosure and robust shock and vibration resistance make it well-suited for the demanding marine environment.

Key Features:

• Reduces compressor startup current by up to 70% for smooth, quiet AC startups
