Panel Mount Resistors

The addition of aluminium housed resistors to our range of resistors means that our customers have an increased option when it comes to resistor selection for their application.

Terminology: Panel mount resistors are also referred to in the electronics industry as ‘panel mount resistors’ and ‘aluminium housed resistors’.

Applications; This style of wire wound resistor is used where a small physical size is required (relative to the power rating of the resistor) and a rugged construction of the resistor is required.

Mounting And Heat Sinking: The aluminium housed resistors are typically mounted on a suitable heat sink material by way of the mounting […]

5 Watt Wire Wound Potentiometer

We have had several enquiries for a 5 watt rated wire wound potentiometer for applications ranging from motor control, light dimming, audio equipment and industrial controls. The standard AW potentiometer is rated at 3 watts but can be used in a 5 watt application. The way we achieve a 5 watt rated wire wound potentiometer is to use a dual gang AW potentiomer with the terminals paralleled up to achieve the higher wattage rating required.
Available Resistance Range
Because the AW potentiometer has a resistance range from 1 ohm to 50k ohms (with a linear taper) when the dual gangs are connected in […]

ASW Series Precision Resistor Used In Linear power Supply

The ASW 5 precision wire wound resistor is rated at 6.5 watts and has been used throughout the Australian electronics manufacturing sector for 30 plus years. This series of resistor has been used in many applications where tight tolerance, high inrush of current and long term reliability of operation are required.
400 Watt Linear Power Supply Application
A recent use for this resistor has been in a locally designed 400 watt linear power supply. The trend in power supply design over the last 15 years has been more towards switch mode technology as high efficiency power supply operation is possible and minimal […]

Wire Wound Resistors – Manufacturing In Australia

The Australian manufacturing industry has gone through significant changes over the last 25 years and the electronics manufacturing sector is no different. In an increasingly competitive, price driven manufacturing world, the Australian electronics industry has followed many other industries looking to reduce costs, to move part or all of their electronic manufacturing overseas, notably to China.

This trend to Chinese based manufacturing started in the mid 1980’s and China was seen as a way of slashing manufacturing costs for some Australian companies. Whilst this trend continued for the next 20 years or so, recently we have witnessed a move back to […]

Power Resistors – Light Rail Braking Load Bank

Power Resistor Range And Specifications
There are many applications for a power resistor where a very substantial power rating is required that exceeds the wattage available from our range of power resistors. The current range of power resistors covers a range from power ratings from 5 watts to 1000 watts.

The corresponding ceramic former lengths range from, for example, 51mm for the DG series resistor rated at 20 watts, to 165mm for the HA series 100 watt resistor up to the YM type power resistor that has a 1Kwatt rating and has a ceramic length of 475mm.

There are numerous applications where a […]

Wire Wound Potentiometer For Audio Applications

Wire wound potentiometers have been used widely within the audio visual industry as a superior alternative to carbon based potentiometers for many years. Carbon potentiometers can exhibit the following negative qualities particularly in audio applications:

Carbon potentiometers can be ‘noisy’ electrically. As the carbon elements within the potentiometers age they can begin to generate electrical noise which, when amplified for example, can result in an inferior sound quality audio applications
Potential for failure in higher power applications. Carbon ‘pots’ generally have a lower wattage rating than their wire wound counterparts. This is often the case in high end audio applications employing vacuum […]

Power Resistor – HP 250 Watt Tubular Resistor

The range of tubular power resistors has been expanded to include a 250 watt version of this versatile range of resistors. This makes a useful addition to the range and higher power ratings are now available including 200 watt, 250 watt and 350 watt. High power resistors have been used in hundreds of applications by Australian industry over the last 40 years.
Termination Options For Power Resistors
This range of power resistors has a very versatile range of terminal options to suit different end applications and wiring situations giving manufacturers the ability to quickly wire up the resistors into the finished product. Termination […]

Rheostat – Application Example In Remote Lighting

150 Watt Rheostat Application
Rheostats have been used in dozens of applications over the years. The APR 150 rheostat is rated at 150 watts and has proven to be very reliable in applications in many industries. The lighting industry has used high power rheostats in dimming applications where traditional switch mode light dimming technology is not appropriate due to the need for absolute simplicity and long term reliability of operation.

Recent Application In Agriculture in remote N.S.W.

A fairly unusual request from a client was received early this year. The client has a large property in central N.S.W. and needed a simple, cost effective and […]

Power Resistors – HA series power resistor application – Industrial Fan Speed Control

Application In Industrial Oven Manufacture
A Sydney based client approached us as they needed assistance in finding a suitable solution for an oven fan speed control application. The client manufactures a range of industrial ovens used for a variety of purposes from paint curing to baking enamel finishes onto metallic machined components. The ovens are constructed and designed using a motorised conveyer belt system that feeds the required items into a heating chamber which is heated by way of a number of high power industrial heating elements. When the items exit through the oven they then need to be slowly cooled […]

Working With A Resistor Manufacturer

Australian Based Resistor Manufacturing Offers Benefits To Local Industry
Having a locally based manufacturer of wire wound resistors and power resistors is hugely beneficial for Australian industry as it allows local designers and manufacturers the following benefits:

Resistor customisation service. Given that the nature of Australian industry is generally ‘niche’ focused, it it often the case that local manufacturers need custom resistor solutions rather than ‘off the shelf’ products. Customisation of resistors can include many areas including resistor values, resistor tolerances, non- standard power ratings, different types of terminations and unique ways of mounting the resistors assembly. Recent examples include custom shaft […]
