HAT220A/HAT240A ATS controller has microprocessor as its core, can accurately detect 2 ways-3 phase, 2 ways-1 phase or 2ways-2phase voltage and also can make accurate judgment to conditions of abnormal voltage (loss of electricity, over or under voltage), control ATS to transfer after delay. Controller also has a function of sending start signal to genset when one power is abnormal.
PERFORMANCE AND CHARACTERISTICS
Controller detect multi-voltage conditions, such as 2ways-3phase voltage, 1phase voltage (could be 2 ways mains, 2ways gens, or 1mains-1gens), or 2ways-2phase voltage. Its performance and characteristics show as following,
- Realizing the computer programming control, can use computer to set abnormal voltage delay, switch priority, genset shutdown delay, the voltage correction and other functions, fully graphical interface operation. When programming by computer, the controller front panel must be opened, then use SG72 interface module (USB to LINK) via the PC test software. About PC software’s operation, please refer to “software manual of HAT220A/HAT240A”.
- The voltage normal delay of #I or #II can be set (0~60) seconds and the start Genset delay can be set (0~90) seconds.
- The voltage abnormal delay of #I or #II can be set (0~60) seconds and the stop Genset delay can be set (0~90) seconds.
- “#I power supply priority”, “Auto/Manual”, “No priority” and “#II power supply priority” can be set via controller front panel and in order to ensure #I power supply priority power on or #II , or no priority power on for examine and repair.
- Design of 2 ways N line isolate.
- LEDs mounted on front panel can clearly show ATS running status.
- The #I and #II power supply transfer relay’s (CLOSE 1#, CLOSE 2#) output contactor capacity is 16A 250VAC/16A 28VDC, and they belong to passive contactor, can be directly used in driving switch to transfer.
- The Genset start relay’s (GENS START) output contactor capacity is 7A 250VAC/7A 28VDC, and they belong to passive normally closed contacts.
- Controller has strong ability for anti-electromagnetic interference, and very suitable for using in strong electromagnetic interference of complex environment.
- Modular configuration design, Flame Retardant ABS plastic shell, inserted type connection terminals, small volume, compact structure with easy mounting and maintenance.
