Automatic Transfer Switch ATS Controller Generator Set Dual Power Supply Switch
Automatic Transfer Switch Controller Generator Power Supply Control Board. The powerful Microprocessor contained within the HAT530N ATS controller allows for precision voltage (2-way 3-phase/single phase) measuring and 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 the delay has expired. HAT530N 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 remote (remote control, remote measurement and remote communication). Measure and display 2-way 3 phase Voltage and Frequency.
Over/under voltage, loss of phase, phase sequence wrong, over/under frequency protection function. As default, phase reverse sequence protection and over/under frequency protection are disable; however, users can set the protection function as need. There are overvoltage, undervoltage, phase loss, reverse phase sequence, overfrequency, and underfrequency detection functions.
The factory settings for reverse phase sequence, overfrequency and underfrequency detection functions are disabled, and users can set them according to their needs. The operating parameters of the controller can be set through the host computer test software.
When in use, the LINK port of the controller is connected to the host computer with an SG72 interface module (USB to LINK) or other conversion modules. 1# power supply or 2# power supply normal delay can be set (range 060 seconds). The generator set start delay can be set (range 03600 seconds).1# power supply or 2# power supply abnormal delay can be set (range 060 seconds). Genset shutdown delay can be set (range 03600 seconds). Through the panel buttons, you can set parameters such as "1# main power supply", "2# power supply main use", "mutual backup", "automatic/manual", etc. To realize 1# main power supply and 2# main power supply Power supply or mutual backup power supply.
Close output can be set to pulse or continuous output. Two-way N line separation design. With automatic/manual state switching, in manual mode, the switch can be realized through the panel buttons.Panel LED can clearly display the working status of the switch. Designed with a forced breaking input port, when the input port is valid, the switch is forced to the breaking position (only valid for ATS switches with breaking position). OUTPUT2, which can control the switching of ATS working power supply. The output contact capacity of 1# and 2# power switching relays (1# CLOSE, 2# CLOSE, OPEN) is 5A AC250V, all of which are passive contacts, which can be directly used for driving switch conversion, etc.
The output contact capacity of the generator set start relay (GENS START) is 7A AC250V /7A DC28V, which is a passive normally closed contact. Suitable for a variety of wiring types (three-phase four-wire, single-phase two-wire, two-phase three-wire, three-phase three-wire). Modular structure design, flame retardant ABS shell, pluggable terminals, embedded installation, compact structure, easy installation.
The system type can be set to mains-power generation, power generation-mains power, and mains-mains power. LCD is 132x64, with backlight, two languages?? (Simplified Chinese, English) display, touch button operation. Collect and display two-way three-phase voltage, frequency and phase sequence.
With display of cumulative closing times of A power supply/B power supply. It has the display of current continuous power supply time and accumulated power supply time of A power supply/B power supply.
With overvoltage, undervoltage, overfrequency, underfrequency, phase loss, reverse phase sequence functions. With automatic/manual state switching, in manual mode, the switch can be manually controlled to close and open. All parameters are programmable on site, and password verification is adopted to prevent non-professionals from misoperation.On-site manual test machine can be used to start and stop the generator set. Real-time clock display, with historical record function, can record 50 pieces of data cyclically. It has the function of regular inspection and startup of the generator set, which can be set to run once, monthly or weekly, and whether to run with load or not. AC power supply can be phase voltage (L, N), power supply range: (170277)V.
It is equipped with one RS485 isolated communication interface, using ModBus-RTU communication protocol, with functions of remote control, remote signaling, remote measurement, and remote adjustment, and can remotely control the start and stop of the generator set, and the functions of remote control switch closing and opening. Suitable for a variety of AC system types (three-phase four-wire, single-phase two-wire, two-phase three-wire mode). Suitable for switch type: no breaking position, one breaking position.
