Vishay Intertechnology has introduced a series of high-power, high-current grid resistors. Vishay Milwaukee GRE1 devices combine high power ratings to 6.5 kW and high operating temperatures to 400°C with a robust design.
With high power capability from 1 to 6.5 kW at 40°C, the grid resistors are optimised for capacitor pre-charge and discharge, dynamic braking, load testing, heater and neutral grounding applications in locomotives, harmonic filters and renewable energy and industrial systems. The devices feature a wide resistance range from 0.1 to 24 Ω, with tolerance of ± 10%, and low inductance from 5 to 40 µH.
Featuring a steel plate element, ceramic insulators and multiple taps, the series provides has a welded construction and double insulation for maximum cooling efficiency. Offered in modular or custom designs, the industrial power resistors can be mounted in IP00, IP20 and IP23 enclosures for indoor and outdoor use.
