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.

Regardless of brand or fixture style it is most likely that the driver will go down first. It protects not only surge over voltages max surge current of 40 ka but also power frequency over voltages. Movs tend to degrade gradually after a large surge or multiple small surges. Thermal protection inside surge protection module.

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. This all too common occurrence can be traced back to insufficient surge protection within your led luminaires. Spd modules that are often placed in front of an led driver. Sizes a positive temperature coefficient resistor can help protect leds from over current and over temperature.

Led lighting surge protection modules. Beyond material damage to the luminaires voltage. Our surge protection devices spds and modules are designed to provide protection from transient overvoltage. Figure 4 circuit protection solutions for luminaires and lighting distribution panels.

The mc34844 features led over temperature protection led short protection and led open circuit protection. One of the primary causes for drivers failing early are electricity spikes. Surge protection for led drivers. In the most vulnerable environments the spds can be installed on a din rail.

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. A surge protection subassembly that can suppress excessive surges to lower voltage levels is an optimal way to protect the led luminaire investment. They are thermally protected and built with high quality dependable materials. With the mov removed from the circuit the spd no.

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. A surge protection subassembly that can suppress excessive surges to lower voltage levels is an optimal way to protect the led luminaire investment. The ic includes overvoltage protection overcurrent protection and undervoltage lockout. They wear out led drivers and distribution panels prematurely and increase service interruptions to street lighting.
