About HTS Transfer Switches

Generac HTS transfer switches are a microprocessor-based design for operation in conjunction with the PowerManager® H-100 or G-100 controller. HTS switches monitor utility voltage and frequency, and communicate via a RS485 communication link to the generator controllers. External LED indicate switch position and source status. An external, 3-position test switch allows testing in either normal or fast mode without opening the cabinet.
