Warrick AM1A2 Alternator

The Warrick AM1A2 Alternator is a specialized solid-state alternating relay designed for industrial duplexing applications. Engineered for precision and reliability, this 120VAC level control relay ensures equal wear across multiple pumps or compressors by alternating the lead and lag load upon each opening of the pilot switch. The AM1A2 model features a rugged plug-in design compatible with standard 8-pin sockets, making it a drop-in solution for contractors servicing wastewater lift stations, condensate return systems, and commercial HVAC mechanical rooms. Its dual-load alternating logic eliminates the risk of single-component burnout, ensuring system longevity through balanced run-times. Built for demanding environments, the Warrick sequence controller handles inductive loads with a high-capacity DPDT (Double Pole Double Throw) contact configuration, providing secondary circuit isolation and stable performance during rapid cycling. This component is essential for maintaining duplex pump control synchronization and preventing thermal overload in shared mechanical systems.

• Automatic Load Balancing: Equilibrates mechanical wear across two pumps or motors to extend equipment lifecycle.
• Industrial Build Quality: Encapsulated solid-state circuitry protects against vibration and moisture in boiler rooms and mechanical pits.
• Universal 8-Pin Mounting: Standardized pinout facilitates rapid installation and simplified field replacement.
• LED Status Indicators: Provides immediate visual confirmation of the active load for streamlined troubleshooting.
• Compact Form Factor: Conserves space in control panels while maintaining high-amp switching capabilities.

Common Technical Questions

How does the AM1A2 handle power interruptions?
The internal logic is designed to hold the last position in the sequence, ensuring that the alternation cycle resumes correctly once power is restored to the control circuit.

Can this alternator be used with single-phase motors?
Yes, provided the motor amperage does not exceed the relay's contact rating; typically, it is used as a pilot duty device to trigger larger motor starters or contactors.

Is the AM1A2 compatible with float switches?
This relay is specifically designed to interface with Warrick liquid level controllers and standard N.O. or N.C. float switches used in duplexing pump stations.
