Distribution
This range of Power Wirewound Resistors are wound on continuous glass fibre elements
or have a ceramic core depending on resistance value. The element is housed in a
ceramic case and sealed with an inorganic silica filler. Their construction gives a resistor
with high insulation resistance and low surface temperature, capable of withstanding high
overload currents. These resistors are ideally suited to a variety of applications within
industrial and commercial environments, where performance and reliability are of prime
importance. Applications include fan force ovens, cooker hoods, power supplies and triac
based speed controls. Custom Design Variants in value and style are welcomed.
