What Type of Transfer Switch Do You Need?

Open Transition ATS – You might choose this switch when uninterrupted power is not critical, and safety during the transition is a priority. This switch type is right for systems that tolerate a brief power interruption during the switch between utility and local backup power.

Programmed Transition Switch – This switch makes sense when minimizing residual voltage is needed for the safe restoration of power. This switch type allows residual voltage in circuits to decay before the power is restored, preventing damage and supporting a smooth transition between utility and generator power.

Closed Transition ATS – You might select this switch when even a momentary power interruption is unacceptable. Ideal for applications where continuous power is critical, this automatic transfer switch allows both power sources to be on simultaneously, supporting a seamless switchover without reducing safety standards.

Soft Loading Transfer Switch – We recommend this switch when flexibility in handling variable loads is essential. Like the closed transition ATS but with more ability to adjust load handling, this switch is for operations that require adaptable backup power solutions, at an additional cost.

Bypass Isolation ATS – This is a good choice when you need a high level of capability and engineering. Designed for critical applications such as life support systems, telecommunications, and air traffic control stations. The Bypass Isolation ATS system allows inspection, maintenance, and testing while in operation. This ATS gives uninterrupted power in the most sensitive electrical environments.
