10 watt BPWXLD10 LED driversBias Power’s new 10 watt BPWXLD10 LED drivers, with 350mA or 700mA constant current output, offer dimming capability from 0% to 100% corresponding to a 0VDC to 10VDC input control signal. The driver provides flicker-free performance by maintaining 1% output current regulation over the entire input voltage range of 100-308VAC, 50/60Hz. This wide input range allows lighting manufacturers to meet global needs with just one SKU. LED string voltages up to 30VDC at 350mA or 14VDC at 700mA are supported.

Unlike conventional LED drivers, the BPWXLD10 has unique cold-starting circuitry, tested to -55°C, proven to kick-start LEDs in extreme cold. All modules are specified for full-rated power over the temperature range of -40 to +85°C. The nominal 82% efficiency results in some of the highest lumens/watt, end-to-end efficacy ratings for high-performance LEDs. Performance is based on Bias’ patented* circuit design, incorporating its own custom ASIC controller.

The modules meet NEMA 6P / IP67 moisture and submersion and easily satisfy the strict requirements for outdoor architectural LED lighting, including pathway, accent flood, in-ground, step, wall and under water lighting. Rated for 3,000VAC isolation, they feature inherent over-current; short circuit (shorted string), overload and open-circuit (string break) protection. These capabilities combine to make a superb solution for high-reliability indoor and outdoor LED lighting fixtures.

The ultra-compact square design gives lighting fixture designers options not possible with longer, rectangular packages. The BPWXLD10 measures 2.1 x 2.3 inches, with a height of 1.25 inch. Standard connections are by 11- inch, 18AWG color-coded “flying leads,” with dual-mounting slots to simplify 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.

BPWXLD10 Series AC-DC LED driver modules are available for immediate sampling, with 8-12 week delivery for production. Pricing is competitive with other dimmable drivers.
