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:
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 5A 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.
