Featuring AF technology as standard, AF contactors establish a new industry benchmark. The electronically controlled coil offers multiple benefits over conventional alternatives, and together with ABB’s wide product offering, an optimal configuration, every time.
The electronic system within the AF contactor rectifies the AC or DC control circuit voltage to a DC control voltage that is applied on the coil. The contactor is safely operated in an always optimized condition making it virtually noise free.
The AF contactor features both AC and DC support. With the complete AF contactor range, functionality is improved. Still, the total number of product variants compared to a conventional range is reduced by 90%. Only four coils are required to cover 24 V AC, 20 V DC-500 V AC/DC.
With conventional contactor technology, different contactors were needed for different network voltages. Thanks to the wide operating range of the AF contactors it can operate just as well in Europe as in Asia or North America. The core coil of the AF contactor range covers 100-250 V, AC/DC and 50/60 Hz.
With conventional contactor technology, it is recommended to use an external surge suppressor, an accessory that could cost as much as half the contactor itself. With the AF technology, the surges are handled by the contactor itself and the surge never reaches the control circuit. Neither the surge suppressor nor the actual surge has to be considered anymore. One less product and one less complication to worry about.
