UK based ARCOL Resistors, a long-established specialist in resistor technology, will have a wide range of high power resistors on display at this year's PCIM Europe in Nuremberg. Highlights will include the recently extended HS range of high-power aluminium-housed resistors which now includes a low profile version. Offering an unequalled balance of pulse power capability versus volume, these resistors are a wire-wound design in order to maximise their high pulse capability. The HS range is available in 10 standard power ratings from 10 to 600 watts with liquid-cooled versions available extending the range to 900 watts. Ohmic resistance values are from R005 to 100K, depending on wattage. 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. Also on display will be the ARF low profile wire-wound metal clad resistors. A very flexible design featuring high pulse capability, the ARF series of resistors are ideally suited to braking and inverter/converter applications. Enhanced power levels can be achieved with the addition of a heatsink. Offering a power range of 75 to 600W and resistance values from 2R2 to 1K1 the compact ARF range can operate with a surface temperature up to +250°C and offer a pulse overload capability of 10 x rated power for 5 sec. The ARF resistor range may also be heatsink mounted for increased power dissipation. Completing the high power line-up for PCIM is the FPA600 600W thick film heatsink resistor range, a 600 Watt resistor suitable for liquid or air-cooled heat sink systems. Designed for applications including power, transmission, traction, variable speed drives, power supplies, robotics, motor control and power control devices, the FPA600 series is available over the resistance range R5 to 1M and has an operating temperature range of -55°C to +150°C Tony Daly, Sales Manager of ARCOL Resistors, comments; "The power resistor market is very important to Arcol and we offer a wide range of standard and custom high power resistor solutions. We have been manufacturing resistors for over 60 years and have a great deal of experience which we can offer system designers. Our fast and lean manufacturing processes enable us to offer competitively priced, low minimum order quantities with typical lead times of 3 to 4 weeks." ARCOL's wide range of high power resistors are 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.
