How to safely use electric voltage
The safety of electric voltage can not be controlled independently. The power supply voltage is usually due to the zero line, the zero line contact, the windling line, the old aging of the wire facilities, the increase of electrical appliances and the increase of the imbalance of the phase line.
Lightning and other factors cause voltage to vary from 0-450V level.
Civil electricity voltage, (China) stipulates 220V, + 10%;
When the voltage exceeds the rated voltage of the appliance, the electrical appliances will have different degrees of damage, and the function is abnormal, the safety is buried, and the weight is burned and fire.
Therefore, attention must be paid to voltage protection for electrical appliances.
A variety of voltage protectors, very complex, very complex, also very special, not installed to be able to effect, to wait for the abnormal voltage can be effective, so, it can be installed, according to what button can be tripped, not table.
Energy safety protection;
How to choose:
Over voltage protector is to protect electrical apparatus to work within the rated voltage, to ensure that the function and life are not damaged, and that the hidden danger is not buried, it is not burned by high voltage and fire.
The voltage protector is a special electric device, working between 0-450V when the voltage is abnormal, and the working voltage can not be less than 450V, which is not equal to the operating voltage 220V of the ordinary electrical apparatus.
The faster the response is, the better.
The voltage protection range can be set according to the rated voltage of the electrical appliance.
The closing delay time can be set according to the characteristics of the electrical appliance.
EM-001AM voltage protection
The working voltage is 60-500V, and the voltage of 0-450V is not damaged. The response speed is very fast, and it is a reliable and effective guarantee.
The default voltage protection setting range is 168-253V, 220V/110V, and is suitable for various electrical appliances. This parameter can be customized.
The closing delay time is set to 15 seconds. The delay time of special appliances such as air conditioners and refrigerators is more than 300 seconds. This parameter can be customized.
How to test effectiveness:
The working voltage test, the inlet line directly connected to two fire lines (380-450V) for 4 hours or so, can also be tested with a voltage regulator; other functions can be completed by this machine.
