Spd Surge Protection Device

Surge protective device (SPD) is an indispensable device in the lightning protection of electronic equipment. Its working principle is that under normal conditions, the SPD is in a state of high resistance, so as to ensure the normal operation of the power system; when the power system with the surge current and voltage step by step increase, the resistance of SPD continues to drop, SPD immediately turns on in nanosecond level time, and the surge energy will be turned on It is discharged into the earth through SPD; after the surge, the surge protector quickly returns to the high resistance state, which does not affect the normal operation of the system.

Product Specification

Product Features

1.The green indicator window indicates normal and red indicates fault, indicating replacement, which is clear and easy to distinguish

2.Remote signal monitoring interface can be selected to realize remote monitoring

3.It can be combined to form 2p, 3P, 4P modes, suitable for various power grid systems

4.Standard modular design, simple installation and easy maintenance

63. When the melt is burnt out under short circuit, the sound is very loud, the melting part is big, and there is burning phenomenon in the melting tube. According to the cause of fusing, find out the fault point and remove it.

64. When changing the melt, the specification of melt should be suitable for the nature of load and line current.

65.When replacing the melt, the power must be cut off for replacement to prevent electric shock.

66. Our experts have rich experience in various fields, so we have to provide a wide range of professional solutions for customers in various industries to win competitive advantages for customers.

FAQ

Q1: Why is the surge light on?

A1: The surge light means that the surge protector is functioning and ready to protect. If this light goes out you know you have experienced a surge and the surge protector will no longer protect. The ground light means the surge protector is connected to a proper ground.

Q2: Do appliances need surge protectors?

A2: However, surge protectors are a good idea if you have an off-grid power system or use a generator. These are much more prone to sudden surges, so surge protectors are needed, especially with appliances that are more sensitive to surges, such as computers and medical equipment like CPAP machines.

Q3: How do I protect my fridge from power surges?

A3: The Appliance Surge Protector CSP100R offers vital surge protection for refrigerators and freezers. It prevents spikes in energy caused by storms and electrical power surges from reaching your equipment. The CSP100R provides 900 joules of protection, a surge-protected outlet and a wall tap plug.

Q4: What can a power surge damage?

A4: When a significant power surge occurs, and the electrical pressure exceeds 169 volts, it can cause the connected device and/or wiring to overheat. While smaller surges won't cause the connected components to overheat, the excessive strain caused on the device can, over time, cause it to wear out prematurely.

Q5: Why is half my house without power?

A5: Circuit panel. Look for a breaker that is either off, or partially off, then push it all the way off, then back on. Ah, so, in most cases, if some, but not all, of your houses/apartments power is out, you have most likely tripped a breaker. ... If should reset the part of the house without power.
