LED drivers are an important component in a LED system as they power and modulate the system while also providing reliable operation and protection. PLDS60-B-277A is one of the advanced LED driver products in the market. It is a versatile, robust and reliable LED driver, which provides constant current control suitable for today’s LED lighting lamps. It can be widely used in small lighting systems such as general lighting, stage lighting, and downlights.

Application Field

PLDS60-B-277A is designed to drive LEDs in constant power mode. It supports up to 60 Watts LED power and the voltage input range is widely adjustable from 100 to 277 Volts. The control mode is current mode or voltage mode power, and one or two stage dimming can be selected. PLDS60-B-277A is suitable for LED bulbs, light bars, down lights, wall washers, streetlights, office lights, landscape lighting, etc. It is also suitable for most LED solutions in which a constant output current is required.

Working Principle

PLDS60-B-277A contains a controller, an electromagnetic interference (EMI) filter and a switch mode power supply (SMPS). The controller is the core part that constantly adjusts the output current according to the predetermined values. The EMI filter is designed to reduce or eliminate interference to other components in the system. The SMPS part is responsible for converting the input voltage and current according to the need of the LED. The efficient power management will reduce the power and heat dissipation of the entire system.

PLDS60-B-277A also provides many protection functions. These include over-current protection, short-circuit protection, over-temperature shut-down, under-voltage lock-out and EMI filter protection. With these functions in place, it ensures reliable operation and improved power efficiency.

In conclusion, PLDS60-B-277A is an effective LED driver with a broad application range and reliable protection functions. It has an wide input voltage range, and supports one or two step dimming. The efficient power management and protection functions make PLDS60-B-277A one of the best LED drivers in the market.
