Main features

HBA-T120 (for a single phase power control system)

Automatic setting of load current using a built-in MCU. Used for phase control and zero cross control by a power controller.

Supported CT: MCTL-6-P-N (load current up to 30A), MCTL-12-S56-10L-N (load current up to 100A)

※Available for relay contact or SSR drive control systems

HBA-T130 (for a three phase power control system)

Automatic setting of load current using a built-in MCU. Used for phase control and zero cross control applications by a three phase power controller.

Supported CT: MCTL-6-P-N (load current up to 30A), MCTL-12-S56-10L-N (load current up to 100A)

※Two CTs are used for three phase control.

※Available for relay contact or SSR drive control systems
