ARCOL Resistors, the UK specialist in resistor technology, is extending its HS range of high-power aluminium-housed resistors to include a low profile version offering an enhanced balance of pulse power capability versus volume.
ARCOL HS power resistors are manufactured using a wire-wound design to maximise their high pulse capability and are available in 10 standard power ratings from 10 to 600 watts. Liquid-cooled versions are also available extending the range from 600 to 900 watts. Ohmic resistance values are available over the range R005 to 100K, depending on wattage.
Key specifications include optional non inductive winding, RoHS compliance and manufacture in line with the requirements of mil -18546 and IEC 115. Standard temperature coefficients are typically < 1K 100ppm Std. > 1K 25ppm.
The HS series of resistors are designed for ease of assembly and offer 7 different termination options, more than any comparable product. A wide range of thermal transfer accessories are available as are customised resistor values and terminations.
Commenting Tony Daly, Sales Manager of ARCOL Resistors, said; “Arcol has over 60 years of experience in manufacturing resistors and we operate a fast lean manufacturing process with typical lead times of 3 to 4 weeks. Our HS series of power resistors are accepted as the industry standard design and footprint manufactured in the UK, very competitively priced and available on low minimum order quantities.”
ARCOL’s HS series power resistors are optimised for stability, linearity and reliability, making them suitable for many renewable energy, power supply, traction and industrial applications including; inverter/converter, snubber, braking resistor, inrush limiter, balancing resistor, voltage divider, capacitor discharge , cross over, shunt and power supplies.
