Saves space and cost
Reversing contactor with softstart and current monitoring
The reversing contactor UG 9256 of the DOLD POWERSWITCH series controls economically 3-phase motors with reversing operation up to 4 kW. It includes up to 5 functions in a space saving, only 22.5 mm wide enclosure. Besides the reversing function also softstart and current monitoring are included as well as galvanic isolation to the mains. As option also softstop is available.
This safes material cost for the user, time for installation and set-up, as well as space and wiring in the panel. A built in relay galvanic isolates the load output. While the semiconductors control the softstart the reversing is done by relay contacts. So the hybrid relay combines the advantages of relays with advantages of wear free semiconductors. The users benefit is an extended electrical life and reliability. In addition the availability of the machine or plant is increased by current monitoring and blocking protection.
Most comfortable is the easy setting by frontside potentiometers. Status LEDs allow diagnistics. Integrated temperature monitoring protects the semiconductors against overload. The semiconductors have a high reverse voltage rating of 1600V. Main applications are lifting equipment, reversing drives for doors and bridges, conveyors with blocking protection as well as control drives in process industries.
