New Vishay Intertechnology Grid Resistors Offer High Power Ratings to 6.5 kW and Operating Temperatures to +400 °C

Press release date: May 15, 2014

Devices Feature Welded Construction and Double Insulation for Maximum Reliability

MALVERN, Pa. — Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new 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 6.5 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 released today 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 %, and low inductance from 5 µH to 40 µH.

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. Pricing for U.S. delivery only starts at $250 each.
