PHD Heavy Duty Power Resistors The PHD Heavy Duty Resistor is mainly used for dynamic braking or where a pulse rated resistor is required. • Power rating 200 - 750 watts • 6 wattage sizes • High short term capacity • High element weight for value • Good stability at high temperatures • RoHS Compliant General Notes Ordering Procedure Power ratings Standard continuous ratings are from 200 watts to 750 watts. For pulse ratings refer to the table below. Thermal cut-outs Standard Resistor To specify standard: Series, Watts,Nominal Value, Tolerance, e.g.: PHD300 2R2 K Tolerance (Code) ±5% (J) and ±10% (K) Cut-outs can be fitted to certain resistors which will operate a contact to disconnect the resistor to prevent overload damage. Resistance The minimum and maximum values shown below are those available within a range of standard resistance alloys. You may select any ohmic value between min and max values.
