Silicon Coated Power Wire Wound Resistors

DDR, DNR and DSR series (support Vitreous Enamel coating DDVR)

• DDR - Wire Wound Resistors : 15W - 20000W ( 20kW )
• DNR - Low Inductance Wire Wound Resistors : 15W - 20,000W ( 20kW )
• DDVR - Vitreous Vitreous Enamel Wire Wound Resistors : up to 1kW
• good for Continuous Load and Short Time over Load application
• can be customized as High Current Resistors to handle very High Loading Current, up to hundreds Amperes, for even higher current requirement, please consider our High Current Load Banks and Shunt Resistors series
• can be used to build Resistor Load Bank
• resistance is made according to customer's application need
• support multi-resistances per resistor requirement ( Multi-Terminals )
• support very small ( milli ohm ) and high resistance range
• support Vitreous Enamel coating for harsh conditions requirement
• for very small resistance requirement, please tell working Voltage and loading time. Different Voltage can cause different resistor current. In turn different raw materials and production process are needed to withstand the load current and heat.
• Precision Resistance Tolerance +/-0.1% +/-0.5% +/-1% +/-5% +/-10% +/-20%
• For power larger than 20kW, we suggest using Resistance Box and Load Bank
• support Power, Resistance and Resistor Size not listed below.
• Adjustable Power Resistors - DSR-F, DSR-W, DSR-WB and DSR-H series
• DSR-F : Power up to 20kW. Low cost and 2-9 days delivery lead time.
• DSR-W : Power up to 8kW. Resistance is adjusted by hand wheel. 1-3 weeks delivery lead time.
• DSR-WB : Adjustable Load Box with Hand Wheel with Voltmeter, Ammeter, Watt meter, Thermal Protection, Over Current Protection, Main Power Switch and Cooling System. Rated Power can up to 20kW.
• DSR-H : Power up to 5kW. Resistance is adjusted by a hand holder. 1-3 weeks delivery lead time.
• Resistance is made according to customer's application need.
