metal clad resistors

The IRV/ULV600-1200 (V=vertical) models are our standard higher power, wire wound, metal clad resistors.The ULV600-1200 are the UL approved versions of the IRV600-1200 models. These models have an extrudedaluminium housing providing strong and rugged protection. Options include flying leads or tab terminals andinductive or non-inductive windings. The most common applications for these models are: motor drives, braking and snubber applications and power sources for industrial equipment.SPECIFICATIONSModel PowerRating onHeatsink Resistance Range [ohms] Inductive Non-Inductive Tab TP Tab TS Leads Tab TP Tab TS Leads IRV600 600W 0.1-9 9.1-94 0.1-94 0.1-5.3 5.4-21.2 0.1-21.2 ULV600 0.1-9 9.1-94 0.1-94 0.1-5.3 5.4-21.2 0.1-21.2 IRV800 800W 0.1-11 11.1-112 0.1-112 0.1-7.2 7.2-28.8 0.1-28.8 ULV800 0.1-11 11.1-112 0.14-112 0.1-7.2 7.2-28.8 0.14-28.8 IRV1000 1000W 0.1-18 18.1-140 0.1-140 0.1-9 9.1-36 0.1-36 ULV1000 0.1-18 18.1-140 0.17-140 0.1-9 9.1-36 0.17-36 IRV1200 1200W 0.1-25 25.1-160 0.1-160 0.1-12 12.1-48 0.1-48 ULV1200 0.1-25 25.1-75 0.21-160 0.1-12 12.1-48 0.21-48 IRVavailable tolerances: +-0.5(D), +-1(F), +-2(G), +-5(J), +-10(K)ULV available tolerances: +-2(G), +-5(J), +-10(K)CHARACTERISTICS Values in [ ] mean change in ohmic value after testTemperature Range -55C to +200C Insulation Resistance 20MW minimum Dielectric Strength IRV AC1500V, 3500V, 4500V, 5400V; Max. leakage current: 2mA ULV See Note [1000V+(Voltage Rating X 2) for 1min.
