Aimtec LED Drivers Have Rugged Enclosures

Aimtec has unveiled a range of 22 AC/DC constant-current LED drivers in rugged IP67-rated enclosures. The drivers accept a universal input voltage range of 90-264V AC at 47-63Hz, with certain models accepting inputs of 170-250V AC at 40-63Hz. Output voltages range from 2 to 90V DC and short-circuit, over-current and over-voltage protection preserves longevity and performance under fault conditions - even when operated at or near full load.

Constant output currents range from 0.3 to 4A and feature Power Factor Correction (PFC) as high as 0.98, which helps to reduce the power consumption and improve overall energy efficiency of the LED application. With efficient rates as high as 88 per cent, input-to-output isolation up to 3,000V AC and a small form factor, Aimtec's AC/DC LED drivers provide turnkey solutions that minimise the applications' energy costs and carbon footprint.

Functional at an operating temperature range of -40 to 55C at full load, within waterproof and dust-tight IP67 enclosures, these power supplies can withstand water immersion of up to 1m in depth and protect against all dust infiltration. Aimtec's AC/DC LED drivers are designed to be used in street signs, traffic lights, architectural and industrial lighting applications, in addition to major house-hold appliances.

Aimtec Offers Surface-Mount Switching Regulator

Aimtec has expanded its family of non-isolated, DC-DC switching regulator series with a surface-mount (SMD) version of the step-down switching regulators. Designed in a compact SMD package (15.24mm x 11.82mm x 7.25mm) to support automated assembly, the AMSRL-78-NZ series is suitable for low-profile circuit implementations such as portable- and standby-power applications. Versatile for a number of industrial applications, the AMSRL-78-NZ series is designed to operate at full output power without heatsinking or forced-air cooling below +71C and with output power derating up to +85C.

With four models featuring adjustable output voltages, ranging from 1.8VDC to 15.5VDC, the AMSRL-78-NZ series produces maximum output currents of 500mA at efficiency rates of up to 96 per cent, with low output ripple and noise (25mV p-p) for noise-sensitive applications. Ultra-wide input ranges (up to 6:1) extend from 4.75VDC to 28VDC and allow the products to be powered from unregulated sources. Other features include continuous short-circuit protection on the output and thermal shutdown for added protection in overheating conditions.

The AMSRL-78-NZ input specifications also feature a remote on/off function, which conforms to TTL logic levels. Priced at USD5.60 (GBP3.40) per 1,000+ pieces, the AMSRL-78-NZ series is made with high-quality, RoHS-compliant materials that undergo rigorous quality control to ensure reliability and performance. Samples are available from stock and can be ordered immediately.
