The rated current and coil resistance are measured at a coil temperature of 23C with tolerances of +15%/20% for rated currents and 15% for DC coil resistance. 2. Performance characteristic data are measured at a coil temperature of 23C. 3. AC coil resistance and impedance are provided as reference values (at 60 Hz). 4. Power consumption drop was measured for the above data. When driving transistors, check leakage current and connect a bleeder re- sistor if required. 5.
