Tapped Power Resistors

There are many applications where it is necessary to have one or several “taps’ on a power resistor. This allows to have different resistance values available on a single wire wound resistor. Applications requiring tapped power resistors can include:

power supplies
inverters
industrial controllers
heating element switching
heating and ventillation
automotive
rail signalling
dummy loads
remote controlled doors

As an example, out tubular wire wound resistors can be supplied with taps as specified by the customer. There is a small reduction in the power rating since winding space is lost. Termination to the added taps is generally via standard ‘quick connect’ […]

Power Resistor Application In High Wattage Power Supplies

We receive a large number of enquiries for power resistors for applications in a wide range of power supplies. High wattage power supplies are used in railway power converters and controllers, signalling and safety monitoring systems. The need for pulse tolerant and transient resistant resistors is especially important as the railway environment is electrically “noisy” and swtiching of high voltage transformers can create transients with voltages greater than 1KV for short periods of time (Typically microseconds).

The Y Series of Power Resistors is suitable for applications requiring 500 Watt to 1200 Watt power rating and are especially useful in high temperature environments. […]
