HAT220A/HAT240A Automatic Transfer Switch Controller
HAT220A/HAT240A ATS Controller ISSUE 2011-05-20 Version1.1 Page 4 of 11
1 SUMMARY
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.
2 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
