Commercial Testing Systems



This system is designed to meet the needs of commercial system manufacturers whose products require startup loads exceeding 100 Amps. Testing sequences are typically more comprehensive and have a duration of 10-20 min. This system specializes in multi-circuit and custom testing requirements. Testing sequence can be paused while adjustments and corrections are made.
