S T A N D A R D P A R T N U M B E R S PFE and PFR Series Powr-Rib® Edgewound Edgewound and Round Wire Designed in both Edgewound and Round Wire formats, these rugged resistors can handle 700 to 1000 Watts of power. Specify our Edgewound design for very low resistance and high power capacity. When higher resis- tance with lower power capac- ity is required use our Round Wire design. These resistors are con- structed of a heavy resistance alloy mounted on ceramic insulators and supported by a metal mounting bracket. Metal parts, except for the resistance element, are heav- ily plated to prevent oxidation at high operating temperatures and to prevent corrosion. The mounting bar is slotted on each end to facilitate installa- tion. Edgewound units provide clamp-type terminals, permit- ting a reliable connection which can be moved along the resistive element to obtain intermediate values. S P E C I F I C A T I O N S Electrical Current Rating: Continuous duty as listed on following page. Wattage Rating: 700 to 1,000 (up to 1,600 watts on special order) Resistance Tolerance: ±10% standard, ±5% available Terminals: Clamps, movable along resistor wire for setting intermediate resistance values on Edgewound units (current must be derated in proportion). Temperature Coefficient: ±300 ppm/°C for resistors 50 amps and more ±500 ppm/°C for resistors 47 amps or less Ohmic Values: See chart on fol- lowing page. Mounting: Metal mounting bar is slotted on each end to facilitate installation. Short Term Overload: 10x rated wattage for five seconds
