Vishay Milwaukee GRE2 grid resistors

Vishay Intertechnology has introduced a series of high-power, high-current grid resistors. Offering designers a drop-in replacement for competing solutions, Vishay Milwaukee GRE2 devices combine high power ratings to 24 kW and high operating temperatures to +400°C with a robust design.

With high power capability from to 24 kW at 40°C, the grid resistors are optimised for capacitor precharge and discharge, dynamic braking, load testing, heater and neutral grounding applications in locomotives/transit systems, harmonic filters, renewable energy systems and industrial systems. The devices feature a wide resistance range from 0.25 to 50 Ω, with tolerance of ±10%, and low inductance from 10 to 40 µH.

Featuring a stainless steel plate element, ceramic insulators and multiple taps, the series has a welded construction and double insulation for maximum cooling efficiency. Offered in modular or custom designs, the RoHS-compliant industrial power resistors can be mounted in IP20 (indoor rated) and IP23 (outdoor rated) enclosures to offer the optimised level of protection for the application.
