Aimtec – First AC/DC LED drivers to feature an ultra-cold start-up at -55C

Aimtec has released what it believes to be the industry’s first AC/DC LED drivers to offer an ultra-cold start-up at -55C. This new line of rugged LED drivers is designed to support the integration of SSL technology in extreme cold climates and high altitudes, such as Alaska, Arctic, Antarctic, Siberia and northern Canadian regions, and regions where lighting applications can be subject to severe drops in temperature.

Capable of operating in either constant-current or constant-voltage modes, the AMERx-CAZ series of power supplies also accept flexible input ranges of 90-305VAC at 47-440Hz or 120-430VDC (surge up to 440V) to accommodate the variables involved with the design process from inception to completion.

Available in output power ranges of 61W to 151W, with output currents of 1.8 to 6.3A, the AMER90-CAZ, AMER120-CAZ, and AMER150-CAZ operate at efficiency rates as high as 91%. All models are enclosed in waterproof IP68 cases to ensure uninterrupted performance under the most extreme environmental conditions.

Other important features include power factor correction up to 0.98, and continuous short circuit protection. Over voltage/over current protection are also included to preserve the longevity and performance of the drivers under fault conditions, even when operated at or near full load.

Designed to meet UL8750, UL60950-1, EN55022, class B, EN60529(IP68), EN61347-1, and EN61347-2-13, the new AMERx-CAZ series currently boast the CE mark for compliance to EN55022, class B, EN60529(IP68), EN61347-1, and EN61347-2-13, says the company.
