Silicon Coated Power Wire Wound Resistors -

DDR, DNR and DSR series

• DDR - Wire Wound Resistors : 15W - 20000W ( 20kW )
• DNR - Low Inductance Wire Wound Resistors : 15W - 20,000W ( 20kW )
• can be customized to handle very High Resistor Current, up to hundreds Amperes
• can be used to build Resistor Load Bank

• resistance is made according to customer's application need

• support very small ( milli ohm ) and high resistance range

• for very small resistance requirement, please tell working Voltage, Duty Cycle and loading time. Different Voltage can cause different resistor current. In turn different raw materials and production process are needed to withstand the generated 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

• we can support wattage, 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 a hand wheel. 1-3 weeks delivery lead time.

• DSR-WB : DSR-W Load Box with Voltmeter, Ammeter, Watt meter, Thermal Protection, Over Current Protection and Cooling System

• DSR-H : Power up to 5kW. Resistance is adjusted by a hand holder. 1-3 weeks delivery lead time.

• for rotary adjustable power resistor, please refer to Rheostat series

• for adjustable Power Resistor application note, please refer to the Application page.

• There are more Power Resistors, Adjustable Power Resistors and Rheostats photos.

• even support small quantity order and accept Credit Card

• Prompt Delivery, within 2 - 9 days! e-mail us for pricing.
