Profile: Electric Controller & Mfg. Co. specializes in electric motors. Our product line includes DC & AC crane control, line-ARC AC & DC contactors, magnetic drum brakes , lifting magnet controllers, power limit switches, tab-weld resistors, auxiliary equipment, and DC reduced voltage starters. Our DC crane control panels are used to operate DC series wound motors in both hoist and travel drive applications. This control meets AIST and NEMA standards, and have been developed and refined by EC&M over the last 100 years. These extremely rugged crane control panels use the Class 7004 Type M LINE-ARC contactor, Class 7001 Type K relays, and Class 7001 type ST1 acceleration relays. The controllers can be derated for use in ambient up to 60°C. Our reduced voltage motor starters is designed to meet NEMA standards, rugged mill duty component time limit acceleration.
