Introduction

LED drivers are power sources, which convert electricity into a form that can be safely delivered to the LED. The power driver makes sure that the LED has the correct amount of electrical current to operate in optimum performance, while the constant current LED driver maintains consistent luminosity and brightness of the LED.The PLDA40-840-277A LED driver is a constant current driver primarily used to power LED lighting. It works by converting AC input voltage and regulating current with precision, allowing for the LED to operate at consistent lumens and brightness. This LED driver provides a high-efficiency, reliable platform for LED application designs.

Specifications

The PLDA40-840-277A is designed to accommodate wide range of LED lighting systems, including incorporation into existing fixtures. This LED driver provides a constant current output range of 250mA to 450mA. The rated input voltage is 120V AC and the total load wattage is 40 watts. The efficacy is greater than 80% and comes with an up to 66% power factor. Its compact size makes it a preferred choice for lighting applications and the unit runs without generating any RFI or EMI noise.

Features

The PLDA40-840-277A LED driver boasts a number of innovative features that make it an ideal choice for LED lighting applications. Its zero dimming mode (no dimming) for maximum lamp efficacy is a unique feature that ensures maximum lighting performance even at high wattage levels. The unit features a patented closed loop design that ensures consistent LED output with its adaptive thermal management. Additionally, it has a built-in active power factor correction, which helps to reduce power lost in the AC line.The interchangeable ‘P’ mounting plate included with the LED driver also adds to its convenience as it can be easily installed in any environment. The driver is also protected against short-circuiting, overvoltage, high temperature and overload.Finally, the PLDA40-840-277A has a universal input range, allowing for connectivity with any power source within its specified range. This makes it an ideal choice for a variety of LED lighting applications.
