Surge Protection Device

CHENZHU SPD (surge protection device) lightning surge protection circuit device has a fast and powerful surge current leakage capacity. In the lightning surge interference, the lightning proof surge protector for electrical panel ensures the safety of the industrial automation control system a variety of field equipment and control equipment.

The SPD 3 phase industrial power strip surge protector created by Chenzhu, one of the most professional surge protection device manufacturers, has integrated lightning-proof technology, intrinsic safety explosion-proof technology, and functional automation safety technology. As a result, the SPD electrical surge protection device by CHENZHU, a reliable SPD enterprise, is the first 20kA anti-surge capacity of the leading products in China. The SPD panel box surge protector supplied by CHENZHU is also an important part of the safety automation system like the intrinsic isolated barrier, signal conditioner, safety relay, etc.

Surge Protection Device Types

Signal SPD

Electronic devices are always threatened by power surges and transients caused by power failures or nearby lightning strikes. Signal SPD was born to protect electronic devices in automatic control systems.

Intrinsic Safety 5V Signal SPD

Intrinsic Safety 24V Signal SPD

Signal SPD For 5V

Signal SPD For 24V

Low Power SPD

The surge protector is designed to prevent transient surge conditions. T range SPD for low power supply is used for protecting 24VDC equipment on site or in the control room from being damaged by lightning surge voltage or operating over voltage.

24VDC 10kA Low Power SPD

AC Power SPD

The surge protector is designed to prevent transient surge conditions. Large single surge events, such as lightning, can reach hundreds of thousands of volts and can cause immediate or intermittent equipment failure. However, lightning and power anomalies account for only 20% of instantaneous surges.

20KA AC Power SPD

40KA AC Power SPD

80KA AC Power SPD

DC Power SPD

Like all outdoor buildings, photovoltaic devices are vulnerable to lightning strikes. By far the biggest culprit for the power surges that damage solar panels are direct and indirect lightning strikes on the system. Our DC surge protectors help prevent DC overvolt voltage damage caused by lightning surges and other strong changes in power.

Photovoltaic 1500 DC Power SPD

Screw Mounting SPD

Screw Mounting SPD

CZLBX-48 series surge protective device is designed for protesting devices in the field instruments which is usually caused by lightning strikes.

Screw Mounting SPD Parallel Connection

Network SPD

The network surge protector suppressor protects a data line, including computer network signals, communication devices, and so on. Plug the network surge protector into the data cable and ground it to prevent lightning surges from damaging the device.

Antennas And Feeders SPD

Antennas feeders SPD is used in the antenna feeder circuit of the radio communication station to suppress the induced lightning waves from the antenna feeder to protect the radio communication equipment from lightning strikes.

FAQ of Surge Protection Device

How Does A Surge Protection Device Working?-

Whether it's type 1, 4 pole or type 2, multi pole SPD surge protection device, both type 1 and type 2 surge arresters prevent devices from being damaged by a surge (transient overvoltage) by discharging surge current to the ground. The type 1 & type 2 surge protection unit will be generated. When a lightning strike occurs, the high-power devices are switched on or off, electrostatic charges are discharged. These happen every day.
