 Vishay Milwaukee GRE1

Vishay Intertechnology Inc. has developed a series of high-power, high-current grid resistors. Offering designers a convenient drop-in replacement for competing solutions, Vishay Milwaukee GRE1 devices combine high power ratings to 6.5kW and high operating temperatures to 400°C with a robust design.

With high power capability from 1kW to 6.5kW 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 0.1Ω to 24Ω, with tolerance of ±10 per cent, and low inductance from 5µH to 40µH.

Featuring a steel plate element, ceramic insulators, and multiple taps, the GRE1 series provides high reliability with 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.

Samples and production quantities of the GRE1 series grid resistors are available now, with lead times of four weeks.
