HAT530NC ATS Controller is composed of the core microprocessor, which can precisely measure 3-phase/single phase voltage of 2 ways, make accurate judgment on abnormal voltage (power lost, over/under voltage, over/under frequency, loss of phase, phase sequence wrong), and control ATS to transfer after delay is expired. This controller is suitable for NO Breaking ATS and ONE Breaking ATS. When #1 power is abnormal, the controller will send signal to start genset after the “#1 abnormal delay” has expired. “Three remotes” (remote control, remote measurement and remote communication) functions can be implemented with the help of RS485 communication port. 

PERFORMANCE AND CHARACTERISTICS

● Collect 2-way 3 phase Voltage and Frequency:

1#                                2#

Line voltage   (Uab, Ubc, Uca)    Line voltage   (Uab, Ubc, Uca)

Phase voltage (Ua, Ub, Uc)        Phase voltage (Ua, Ub, Uc)

Frequency    Hz                   Frequency    Hz

● Over/under voltage, loss of phase, phase sequence wrong, over/under frequency detection function. As default, phase reverse sequence detection and over/under frequency detection are disable; however, users can set the function as you need. 

● Controller running parameters can be set by upper computer testing software; At using, controller RS485 port shall connect upper computer by SG72 port module (USB transfers to RS485) or other transfer module. 

● Normal delay of 1# power or 2# power can be set (Range: 0-60s); Genset crank delay can be set (Range: 0-3600s). 

● Abnormal delay of 1# power or 2# power can be set (Range: 0-60s); Genset stop delay can be set (Range: 0-3600s). 

● “1# Master”, “Auto/Manual”, “Each Backup” and “2# Master” can be set via controller front panel, to realize 1# Master power supply, 2# Master power supply or backup for each other to supply power. 

● Close output can be set to pulse or continuous output. 

● 2-way N wire isolated design. 

● Auto/Manual mode transfer. In manual mode, ATS transfer can be implemented via panel pushbutton. 

● LEDs mounted on front panel can clearly show ATS running status.

● Forced Open input port has been designed; When the input port is active, the switch will be Breaking position forcedly (woks only for the ATS with Breaking Position).

● AUX.OUTPUT 1 and AUX.OUTPUT 2 can be configured to make it easy to transfer power supply.

● The output contact capacity of 1# and 2# power supply transfer relay (1#CLOSE, 2#CLOSE, OPEN) is 10A  AC250V, passive contact, can be directly used in driving switch to transfer.

● The output contact capacity of Genset start relay (GENS START) is 7A AC250V/7A DC28V, passive N/C contact.

● Suitable for various AC systems (3-phase 4-wire, single-phase 2-wire, 2-phase 3-wire and 3-phase 3-wire).

● Modular design, retardant ABS plastic shell, pluggable terminal, built-in mounting，compact structure with easy installation.
