metal clad resistors

The EW series of metal clad, edge wound resistors are designed for use in extremely high power inverters. Thebasis for these models are edge wound elements. These are covered by a case which conforms to internationalsafety specifications. This case is powder coated and baked for durability.GENERAL SPECIFICATIONSModel ResistanceRange [ohms] Power Rating ResistanceTolerance Fan Free Air EWS10K 0.5-3.0 6KW 3KW +-0.5(D)+-10(K) EWS13K 1.0-4.0 8KW 4KW EWS20K 1.0-6.0 12KW 6KW EWS26K 1.5-8.0 15KW 7.5KW EWF10K 3.1-18 6KW 3KW EWF13K 4.5-24 8KW 4KW EWF20K 6.1-36 12KW 6KW EWF26K 9.0-48 15KW 7.5KW CHARACTERISTICS1/Temperature Range -55C to +200C 2/Insulation Resistance 20Mohms minimum 3/Dielectric Strength Available options: 1500, 3500, 4500, 5400 (VAC); Max Leakage Current: 2mA 4/Temp.
