HAT270A ATS controller has microprocessor as its core, can accurately monitor 2 ways-3 phase, and also can make accurate judgment conditions of abnormal voltage (loss of electricity, over voltage, under voltage, loss of phase); control ATS to transfer after delay. Controller also has a function of sending start signal to genset when one way power is abnormal. HAT270A is suited for SOCOMEC VS, VE, ATyS3, ATySM3s model and other analogy function ATS switch.

The controller can monitor two ways 3phase voltage (it possibly is two ways mains, two ways gens, or is 1 mains-1 gens) and control ATS to transfer. 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 HAT270A”.

◇#I power supply or #II power supply normal delay can be set range (0~60) seconds. Genset start delay can be set range (0~60) seconds;

◇#I power supply or #II power supply abnormal delay can be set range (0~60) seconds. Genset stop delay can be set range (0~90) seconds;

◇Design of 2 ways N line isolate;

◇The controller design have breaking off compulsorily input port, when input is active, ATS will transfer compulsorily to OFF position;

◇Panel LED can clearly show switch working position;

◇Have a dual power supply change-over circuit output, the output LO, NO (5A 250V AC) can be applied directly to the power supply as ATS;

◇Genset start relay(GENS START) output contact capacity for 7A/28VDC, passive normally close contact;

◇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, flush type installation, compactness, compact structure, easy installation.

◇Power supply input

The controller AC power supply: AC230V±20% (50/60Hz) (sensing from #I and #II A, N phase)

Measure voltage: rated 380V 50/60Hz 3-phase 4-wire, and other measure voltage class, please consults before ordering.

◇Threshold setting point

Over-voltage threshold: 264V (adjust only via PC).

Under voltage threshold: 172V (adjust only via PC).

◇Action time

Closing breaker time: 5 seconds, if detected during the closing breaker the closing status signal is active, then immediately disconnected.

Opening breaker time: 3 seconds, if detected during the open breaker the open status signal is active, then immediately disconnected.

Voltage normal delay: (0~60) seconds (via controller panel potentiometer adjustment).

Voltage abnormal delay (0~60) seconds, default: 5 seconds (only via controller panel potentiometer adjustment).

Genset start delay: when #I confirmed abnormally, delay for (0~60) seconds, (default: 10 seconds, can be adjusted on the panel.)

Genset stop delay: when #I confirmed normally, delay (0~60) seconds, (default: 90 seconds, can via controller panel potentiometer or PC adjustment).

◇I /#II closing status monitoring (can via controller panel key-press programmed)

Default: detect #I/II closing status input port, the controller must access the closing status signal.

◇Power supply consumption

Device voltage looping at rated voltage of the power supply consumption of less than 2VA.

◇Environment condition

Temperature: (-30~+70)ºC　Humidity: (20~95)%

◇Weight

Net weight: 0.47Kg
