Bias Power Low-Power, Ruggedized AC-DC LED Drivers Meet Harsh Requirements for Outdoor Lighting


Buffalo Grove, IL - Bias Power's new BPWXL Series of 4, 6 and 10 Watt constant current LED drivers offer 350mA constant current operation with 1% regulation over the entire input voltage range of 100-308VAC, 50/60Hz. Additionally, the drivers have unique cold-starting circuitry tested to -55°C, proven to kick-start LEDs, even in frigid outdoor lighting fixture designs. The LED drivers are based on Bias' patented* circuit designs incorporating a custom ASIC controller.

Bias ruggedized LED drivers are superb solutions for new indoor and outdoor LED lighting fixtures.

The modules meet NEMA 6P / IP67 moisture and submersion and easily satisfy the strict requirements for outdoor architectural, building and low-bay garage LED lighting. The LED drivers are rated for 3,000VAC isolation and feature inherent over-current, short circuit (shorted string), overload and open circuit (string break) protection. All modules are specified for full-rated power over the temperature range of -40 to +85°C. The nominal 80% efficiency results in some of the highest lumens/watt, end-to-end efficacy ratings for LED solutions in the market today.

With a footprint of only 1.3 x 1.9 inches and height of less than 1 inch, the BPWXL6 provides up to 6 Watts of output power for LED string voltages up to 21VDC. In the same package, the BPWXL4 provides up to 4 Watts of output power for LED string voltages up to 12VDC. The BPXL10 is a 10 Watt driver for LED strings rated up to 30VDC, and has a package size of 2.1 x 2.3 inches with a height of 1.25 inch. Standard connections are 11 inch, 18AWG 'flying leads' with dual mounting slots for ease of installation.

Bias Power LED Driver modules comply with UL/CSA and EN Product Safety Requirements (UL8750 Class 2) and meet conducted EMI emissions EN 55022, Class B and FCC Part 15, Class B. The modules have an MTBF rating of >500K operating hours.

BPWXL Series AC-DC constant current LED driver modules are available for immediate sampling with 4-6 week delivery for production. Pricing begins at under $15.00 in OEM quantities. Dimmable versions will be offered in the near future. For more details, contact Bias Power, Inc., 1330 Busch Parkway, Buffalo Grove, IL 60089. Phone 847-215-2427; Fax 847-215-2914. Product data at:
