200-240VAC CC 10/20/40/60-Watt TRIAC Phase-cut Dimmable LED Driver

Product Introduction

The SCPOWER KIF-TDH Series is a Triac dimmable constant current LED driver designed for LED fixtures operating from a 200–240VAC input supply. Available in 10W, 20W, 40W, and 60W models, it provides flexible constant current output configuration, with selectable settings covering 3–50V and 100–2100mA through DIP switches. This makes it suitable for a wide range of constant current LED modules and fixtures.

The dimmable LED driver supports TRIAC phase-cut dimming and can be configured for both Leading Edge and Trailing Edge dimming. DIP Switch 1 allows users to select the dimming mode, with ON for Leading Edge Dimming and OFF for Trailing Edge Dimming, providing convenient compatibility with different dimmer types and LED lighting systems.

What sets the KIF-TDH Series apart is the combination of NFC configuration and DIP switch adjustment, giving LED driver manufacturers and installers two practical ways to configure the output according to different LED module requirements. This flexible configuration method helps simplify production setup, installation, and repeatable output adjustment.

With a 50/60Hz rated frequency and a power factor of 0.9, the driver delivers stable performance for professional LED lighting applications. It operates across a wide -40°C to +60°C working temperature range, subject to the applicable derating curve, making it suitable for a variety of operating environments.

Designed for constant current LED fixtures where flexible output configuration, dimming compatibility, and repeatable setup are important, the KIF-TDH Series LED power supply provides a practical solution for manufacturers, installers, and lighting projects.

Connecting Diagram

TRIAC Dimmable LED Driver - Constant Current Output

• 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. At input area of KIF-TDH series: ON key for leading edge; 1 key for trailing edge

  (see below picture).

  

• 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.
