grid resistorsVishay Intertechnology, Inc. (Malvern, PA) introduced a new 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 kW to 6.5 kW at +40°C, the grid resistors are optimized 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 Ω to 24 Ω, with tolerance of ±10 percent.
  • Low inductance from 5 µH to 40 µH.
  • A steel plate element, ceramic insulators, and multiple taps.
  • Welded construction.
  • Double insulation for cooling efficiency.
