Surge Protection Circuit For Led Driver

Due to the sensitive nature of led lights we need to provide over voltage over current surge protection for led lighting systems the most common type of surge protector contains a component called a metal oxide varistor or mov which diverts the extra voltage energy away from the device it is protecting.

Surge protection circuit for led driver.

The most common type of surge protector contains a component called a metal oxide varistor or mov which diverts the extra voltage away from the device it is protecting. It protects not only surge over voltages max surge current of 40 ka but also power frequency over voltages. This all too common occurrence can be traced back to insufficient surge protection within your led luminaires. Beyond material damage to the luminaires voltage.

A surge protection subassembly that can suppress excessive surges to lower voltage levels is an optimal way to protect the led luminaire investment. The drivers powering the leds failed prematurely. In the most vulnerable environments the spds can be installed on a din rail. The mc34844 features led over temperature protection led short protection and led open circuit protection.

Movs are widely used in surge protection circuits because of their fast response times high surge energy capability cost effectiveness and. Spd modules that are often placed in front of an led driver. The challenges of surge protection the need for protection voltage surges have a huge destructive impact upon public lighting systems. Figure 4 circuit protection solutions for luminaires and lighting distribution panels.

Our surge protection devices spds and modules are designed to provide protection from transient overvoltage. They wear out led drivers and distribution panels prematurely and increase service interruptions to street lighting. Regardless of brand or fixture style it is most likely that the driver will go down first. Surge protection for led drivers.

One of the primary causes for drivers failing early are electricity spikes. Led lighting surge protection modules. Sizes a positive temperature coefficient resistor can help protect leds from over current and over temperature. Fuse and inline fuse holder at pole base overcurrent protection for wiring in the pole to the luminaire may or may not be installed 2.

Thermal protection inside surge protection module. They are thermally protected and built with high quality dependable materials. Open circuit led protection device tvs diode transient protection for energy let through to the led circuit mov surge protection device with high surge withstand movs e g 25 34mm dia. The ic includes overvoltage protection overcurrent protection and undervoltage lockout.
