Dimmable 10 Watt, AC-DC LED Drivers MeetHarsh Requirements, Offer Cold-Starting, Universal100-308VAC Input

Bias Power’s new 10 watt BPOXLD10 LED drivers offer 350mA constant current operation with 1% regulation over the entire input voltage range of 100-308VAC, 50/60Hz. LED string voltages up to 30VDC at 350mA or 14VDC at 700mA are supported. The drivers are dimmable and adjust output current based on either 0-10 VDC reference or ELV/Triac tracking. A constant-voltage version handles LED string voltages up to 12VDC. Either is compatible with digital control circuitry.

Unlike conventional LED drivers, the BPOXLD10 has unique cold-starting circuitry, tested to -55°C;   proven to kick-start LEDs in extreme cold.  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.  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.  

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 LED solutions in the market today.  Performance is based on Bias’ patented* circuit design, incorporating its own custom ASIC controller.

The ultra-compact square design gives lighting designers options not possible with longer, rectangular packages.  The BPOXLD10 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.
