metal clad resistors

The IRP high power resistor line can handle power of up to 3000W in free air. These models are comprisedof multiple resistors housed in a rugged steel protective cover. The base is zinc plated steel. The coveris powder coated which is baked, rendering it extremely strong. The major application for this modelrange is high power inverter braking resistors.GENERAL SPECIFICATIONSModel Free AirPowerRating [W] Resistance Range [ohms] ResistanceTolerance Inductive Non-Inductive IRP1000 400 0.1-140 0.1-36 +-0.5(D)+-1.0(F)+-2.0(G)+-5.0(J)+-10(K) IRP2000 800 0.1-280 0.1-72 IRP3000 1100 0.1-420 0.1-108 IRP4000 1400 0.1-560 0.1-144 IRP5000 1600 0.1-700 0.1-180 IRP6000 1800 0.1-840 0.1-216 IRP7000 2100 0.1-980 0.1-252 IRP8000 2400 0.1-1120 0.1-288 IRP9000 2700 0.1-1260 0.1-324 IRP10000 3000 0.1-1400 0.1-360 CHARACTERISTICS1/Temperature Range -55C to +200C 2/Insulation Resistance 20Mohms minimum 3/Dielectric Strength Available options: 1500, 2500, 3500 (VAC); Max Leakage Current: 2mA 4/Temp.
