10W Triac LED Driver Constant-Current Circular 100-277VAC Fixtures

Product Overview

This isolated, constant current circular LED power supply features a universal 100-277VAC 50/60Hz input range, with a wide 3V-42V output voltage window and adjustable output current from 100mA to 450mA via DIP switch, eliminating the need for custom firmware or specialized programming. With a compact circular form factor designed for seamless in-fixture mounting, this 100-277VAC constant current LED driver holds UL & cUL, FCC, CE, and RoHS certifications, rated for dry and damp locations, and backed by a 5-year manufacturer warranty. Its industry-leading 5-in-1 dimming compatibility and flicker-free performance make it the go-to power solution for commercial and residential LED fixture production and retrofit projects.

Key Features & Competitive Advantages

Versatile 5-in-1 Dimming Compatibility

Unlike single-mode dimming drivers, our 5-in-1 dimmable 10W LED power supply supports Triac/Phase, 0-10V, 1-10V, potentiometer, and 10V PWM dimming in a single unit, eliminating the need for multiple SKUs for fixture manufacturers. It delivers smooth 1%-100% dimming range with leading and trailing edge Triac dimmer compatibility, ensuring seamless integration with existing commercial lighting control systems without hum, flicker, or drop-out at low brightness levels.

Compact Circular Design & Flexible Parameter Tuning

With a compact footprint of 64.4×58.4×24mm circular form factor, this circular LED driver for downlights and fixtures fits seamlessly into the housing of recessed downlights, spotlights, cabinet lights, and accent fixtures, with no modification required for standard fixture designs. The integrated DIP switch enables tool-free adjustment of output current across 8 preset levels from 100mA to 450mA, allowing fixture manufacturers to match the driver to diverse LED chip configurations with a single part number, reducing inventory costs and simplifying supply chain management.

Reliable Safety & In-Fixture Performance

Equipped with built-in PFC power factor correction, this UL listed 10W Triac LED driver meets global energy efficiency standards for commercial lighting, with comprehensive short circuit and over temperature protection to safeguard both the driver and connected LED load. It uses free air convection cooling for stable operation even in confined in-fixture spaces, with an IP20 rating approved for dry and damp locations, including bathroom vanity fixtures, covered outdoor accent lights, and commercial kitchen task lighting. Its flicker-free design ensures consistent light output, eliminating eye strain in commercial office and hospitality environments, and meeting international standards for video-friendly lighting.

Ideal Application Scenarios

This constant current Triac LED driver for commercial fixtures is optimized for a wide range of professional use cases, including:

• Recessed commercial downlights, spotlights, and track lights for office, retail, and hospitality spaces

• Cabinet and display lighting for retail showrooms, grocery stores, and museum exhibits requiring precise constant current control

• Lighting retrofit projects for commercial buildings, hotels, and institutional facilities, with universal input voltage and dimming compatibility for existing wiring infrastructure

• High-end residential integrated LED fixtures, with compact circular design for seamless in-fixture mounting

• Healthcare and educational facility lighting, with flicker-free performance to support occupant comfort and productivity

Installation & Wiring Guidance

For fixture manufacturers and professional installers, follow these core installation guidelines for optimal reliability:

• Always disconnect all electrical power before wiring or installation to prevent electrical shock and equipment damage.

• Input wiring: Connect the AC line (L) and neutral (N) wires to the corresponding input terminals, with proper grounding to comply with local electrical codes.

• Output wiring: Match the positive and negative DC output terminals to the LED load, ensuring strict polarity alignment to avoid permanent damage to the LED chips.

• Dimming wiring: For Triac dimming, connect the driver to a compatible leading or trailing edge Triac dimmer; for 0-10V/1-10V/PWM dimming, connect the corresponding signal wires to the dimming controller, following the provided wiring diagram.

• Adjust the output current via the integrated DIP switch before powering on the unit, and mount the driver in a well-ventilated area within the fixture housing, avoiding direct contact with heat-generating LED heat sinks.
