Yi Min EM-001A photovoltaic grid connected special protector anti islanding detection device

Photovoltaic grid connected special protector / anti isolated island detection device

Model: EM-001A

Product overview

EM-001A series automatic reclosing protector is a new generation of high tech security electric products developed successfully with electronic technology. It has the protection function of overvoltage, undervoltage, short circuit, lightning protection and other main electrical faults.

It is widely used in distributed grid system of photovoltaic power generation, communication base station, satellite ground receiving station, microwave transmission station, electric vehicle charging pile, outdoor integrated cabinet, integrated access, special equipment chassis, safe city public security monitoring project, public security card port, intelligent transportation, intelligent city and other unattended equipment.

Product function

1. overvoltage protection: the voltage is too high, so that the equipment is burned out and the supply voltage is higher than 242 volts (the default value can be set). The automatic reclosing protector is broken. When the voltage drops back to normal, the automatic reclosing power protector automatically switches on and energized.

2. undervoltage protection: the voltage is too high, it is dangerous, and the voltage is too low can also cause the equipment to start frequently, to the equipment damage, the power supply voltage is lower than 198 volts (the default value, can be set), the automatic reclosing protector is disconnected. After the voltage rises normal, the automatic reclosing protector automatically switches on and energized.

3. automatic disconnection during power failure: when the line is cut off, the input and output lines are automatically disconnected. It avoids the occurrence of electric appliances burning when the power is not normal when the caller is called again. When the call is repeated, if the power supply is normal, the switch will be energized automatically.

4. check before closing: the automatic reclosing power protector checks the line before closing. If the power supply voltage is abnormal (too high, too low) and the zero line is disconnected, the closure will be closed and displayed. If the user does not repair it in time, the fault can not be switched on, and the accident will be prevented before the accident. Life.

5. reclosing function: online automatic detection, after the supply voltage is normal, the power supply is automatically restored without manual closing.

6. display function: LED display, voltage value and fault information at a glance.

7. low power consumption: self power less than 1W

Product use

The EM-001A series automatic reclosing electric protector has the function of voltage tripping, voltage abnormal tripping, and checking with calendering. It can meet the voltage protection requirements of the distributed photovoltaic power generation system, and it also has the function of short circuit and lightning protection, which can reduce the equipment barrier rate, reduce the maintenance and maintenance cost. Improve the security and stability of the system.
