Silicon Coated Wire Wound Resistor -

DDR and DNR series

• DDR - WireWound Resistor : 15W - 20,000W ( 20kW )
• DNR - Low Inductive WireWound Resistor : 15W - 20,000W ( 20kW )
• Adjustable Power Resistor - DSR series is available, for rotary adjustable power resistor, please refer to Rheostat series
• can be customized to handle very HIGH resistor current, up to hundreds Amperes
• resistance is made according to customer's application need
• support very small ( milli ohm ) and high resistance range
• support Precision Resistance Tolerance requirement

• in case of very small resistance is needed, please tell working Voltage and Duty Cycle. Different Voltage can cause different resistor current. In turn different raw materials and production process are needed to withstand the generated current and heat.

• For power larger than 20kW, we suggest using Resistance Box and Load Bank
• we can support wattage, resistance and resistor size not listed below.
• even support small quantity order and accept Credit Card
• Prompt Delivery, within 4 - 8 days! e-mail us for pricing.
