Y-700 Automatic transfer switch controller
is a intelligent automatic transfer module with programmable,automate measure,LCD display and digital communication etc function. It combines digital, intelligent and networked together. It achieve measure and control process automatically,reduce human operation error. It's the ideal product of dual power transfer. The core part of Y-700 Automatic transfer switch controller is microprocessor. It could detect the three phase voltage of Main power and Emergency power accurately. When the voltage abnormal(overvoltage,undervoltage, phase loss,overfrequency,underfrequency),it could make accurate judgment and then output passive control signals. This device could apply in different kinds of ATS. Such as specialized ATS,contactor type ATS,circuit breaker type ATS and so on. The controller with compact structure,advanced circuit and high reliability. So it can widely used in the electrical devices or automatic control system of electricity, telecommunication,petroleum,coal,metallurgy,railway,municipal,intelligent building etc industry.
□ Controller with overvoltage,undervoltage,phase loss,reverse phase sequence,overfrequency and underfrequency protection function.
□ It can choose Automatic working status or Manual working status. In the Manual working status,could close or open switch by press the button.
□ All the parameters could be programmed on the scene. Adopt secondary password to prevent wrong operation.
□ On the scene,it could test the genset in with load or without load mode.
□ With functions of switch reclosing and the power button again.
□ Output signal could set to be pulse or continuous output.
□ It can apply to one off position switch,two off position switch and without off position switch.
□ The neutral line of Main power and Emergency power are designed separately.
□ Real time clock display.
□ With function of timing start or stop genset. The cycle could set to be a single running, once a week running or once a month running. And all the cycle running method could choose with load or without load.
□ Controller can control 2 units genset cycle running. The running time and the interval downtime of genset both could be set.
□ The range of DC power is very wide. Can short time withstand 80V DC input. Or through HWS560(85V-560VAC input,12VDC output) power module to supply power.
□ The distance of AC power input terminals is far,so it can maximum withstand 625V input.
□ Controller has RS485 isolation communication interface. It's apply protocols of Mod Bus communication will achieve "remote controlling,remote measuring,remote communication" functions. It could remote control genset start or stop and remote control ATS closing or open.
□ It could inquiry the current state of controller(contain input port,overvoltage,undervoltage etc Internal Digital data).
□ Suitable for a variety of connection types(Three phase four wire,Three phase three wire, Single phase two wire,Two phase three wire).
□ Modular structure design,flame retardant ABS shell,pluggable terminal blocks,embedded installation,structure compact and easy installation Technical Parameter
