TLD Series – LED Drivers
20-40 Watt Single Output Encapsulated Switching Power Supply with PFC for Indoor & Outdoor IP66/NEMA 4 Applications.
LED drivers are an essential element of any LED lighting project or installation. The issue is that LED lighting is vulnerable to thermal runaway. As ambient temperatures increase, the amount of forward voltage (the volts required by the light-emitting diode to conduct electricity and light up) decreases and the LEDs will draw more current, heating up until they burn out.
To solve this problem, the LED driver is a self-contained power supply that regulates its output current to match what is needed by the LED lights, thereby keeping the current constant and avoiding thermal runaway.
