Surge Protection Circuit For Led Driver

In the most vulnerable environments the spds can be installed on a din rail.

Surge protection circuit for led driver.

It protects not only surge over voltages max surge current of 40 ka but also power frequency over voltages. Surge protection for led drivers. Movs are widely used in surge protection circuits because of their fast response times high surge energy capability cost effectiveness and. The drivers powering the leds failed prematurely.

The ic includes overvoltage protection overcurrent protection and undervoltage lockout. Spd modules that are often placed in front of an led driver. Our surge protection devices spds and modules are designed to provide protection from transient overvoltage. 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.

Sizes a positive temperature coefficient resistor can help protect leds from over current and over temperature. Movs tend to degrade gradually after a large surge or multiple small surges. They wear out led drivers and distribution panels prematurely and increase service interruptions to street lighting. Led lighting surge protection modules.

Thermal protection inside surge protection module. 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 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. Beyond material damage to the luminaires voltage.

With the mov removed from the circuit the spd no. Regardless of brand or fixture style it is most likely that the driver will go down first. Figure 4 circuit protection solutions for luminaires and lighting distribution panels. This all too common occurrence can be traced back to insufficient surge protection within your led luminaires.

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. The challenges of surge protection the need for protection voltage surges have a huge destructive impact upon public lighting systems. 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.
