metal clad resistors
Product Details
These economical and powerful components comprise two, three or four high power resistors housed in partial steel covers at each end. These rugged, powder coated covers ensure anexcellent seal. The internal resistors use aluminum plates at each end instead of ourstandard cement molding. This innovation reduces construction time and reduces cost,at no reduction of performance. The major application of this exciting new model is highpower inverter braking units.GENERAL SPECIFICATIONSMODEL InternalResistor Type Power Rating in free air [W] ResistanceRange[ohms] ResistanceTolerance LCA 3.2K IRV1600X2 1.0k 2.3 - 160 J[+-5%]K[+-10%] LCA 4.0K IRV2000X2 1.2k 3.0 - 220 LCA 4.8K IRV2400X2 1.3k 4.0 - 280 LCA 5.6K IRV2800X2 1.4k 4.5 - 270 LCA 4.8K IRV1600X3 1.3k 0.75 - 265 LCA 6.0K IRV2000X3 1.4k 1.0 - 330 LCA 7.2K IRV2400X3 1.5k 1.5 - 420 LCA 9.6K IRV2800X3 1.6k 1.5 - 390 LCA 6.4K IRV1600X4 1.7k 0.5 - 340 LCA 8.0K IRV2000X4 1.9k 0.75 - 440 LCA 9.6K IRV2400X4 2.1k 1.0 - 560 LCA 11.2K IRV2800X4 2.3k 1.1 - 520 CHARACTERISTICS Values in [ ] mean change in ohmic value after testTemperature Range -55C - 275C Insulation Resistance 20Mohms min.
