100-277VAC CC 10W/20W/40W/60W DIP Switch Current Adjustable Triac Dimmable Driver

Product Introduction

The Constant Current LED Driver is designed to provide a stable and regulated current output for a wide range of constant current LED lighting applications. Available in 10W, 20W, 40W, and 60W models, it supports configurable output ranges of 3–50V and 100–2100mA, making it suitable for different LED modules and fixtures.

With a 100–277VAC input voltage range, the driver operates at 50–60Hz and provides a current tolerance of ±5% for consistent LED performance. Its power factor of >0.9 and efficiency of over 83% help improve overall power utilization and operating efficiency.

The driver supports TRIAC / phase-cut dimming and is compatible with both Leading Edge and Trailing Edge TRIAC dimmers, providing flexible dimming control for LED lighting systems.

Designed for reliable indoor operation, the driver supports a working temperature range of -40°C to +80°C. Its IP20-rated housing is intended for indoor applications and should be installed in locations protected from direct exposure to water and outdoor environmental conditions.

With flexible output configuration, wide input voltage compatibility, and TRIAC phase-cut dimming, this constant current LED driver provides a practical solution for residential, commercial, retail, architectural, and other indoor LED lighting applications.

Application

The TRIAC Dimmable LED Driver is designed for constant current LED lighting products, rather than constant voltage LED strips. It is particularly suitable for LED fixtures with integrated LED modules, where the driver's output current and voltage need to be matched to the requirements of the LED board.

Typical applications include:

• LED Downlights

• Commercial Ceiling Fixtures

• LED Panel Lights

• Spotlights

• Recessed Lighting

• Integrated LED Luminaires

The appropriate driver model should always be selected according to the LED module's required operating current, voltage range, and power rating to ensure reliable and stable performance.

TRIAC Dimmable LED Driver - Constant Current Output

TRIAC/Phase cut dimming

• Output constant current level can be adjusted through input terminal of the AC phase line(L) by connection a Triac dimmer.

• Usually matching with leading edge and trailing edge both.

• Please try to use the small power dimmer, have access to a wider dimming range, high-power dimmer is difficult to achieve the output current to zero.

• Please try to use dimmers with power at least 2 times as the output power of the driver.
