metal clad resistors

The FGRA series of high power, fiber glass resistors are designed for use in high power inverters. The basisfor these models are wire wound elements with a fiber glass core. These are covered by a case whichconforms to international safety specifications. This case is powder coated and baked for durability.GENERAL SPECIFICATIONSModel ResistanceRange [ohms] Power Rating ResistanceTolerance Fan Free Air FGRA6600 1.83-700 4KW 2KW +-0.5(D) +-1.0(F)+-2.0(G) +-5.0(J)+-10(K) FGRA8300 1.4-1200 5KW 2.5KW FGRA10000 1.3-1050 6KW 3KW 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.
