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.
