With high power capability from 4 to 24kW at +40 °C, the grid resistors released are optimised for capacitor pre-charge 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 50Ω, with tolerance of ± 10%, and low inductance from 10 to 40µH.
Featuring a stainless steel plate element, ceramic insulators and multiple taps, the GRE2 series provides high reliability with 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.
