Rheostats have been used in the electrical and electronics industries since the 1920’s and still have a place in modern engineering. The rheostat has the following benefits:
- ability to vary and control electrical resistance at relatively high power ratings
- available as an ‘off the shelf’ (short lead time) device
- quickly and easily mounted
- rugged, ‘tried and tested’ design
- ease of termination of wiring
We currently manufacture our rheostat range in the following wattages;
- 25 watt
- 50 watt
- 150 watt
- 300 watt
- 500 watt
Rheostat Specifications:
The ‘APR’ series has been manufactured in Australia for well over 50 years and has a reputation for offering the highest levels of reliability, both electrically and mechanically. It is ruggedly constructed and offers very compact construction. Specifications include:
- resistance tolerance of +-10%
- insulation resistance 100 M ohm / dc 500v
- dielectric strength 1000 Vac / 1 minute minimum
- mechanical rotation life 10,000 turns minimum
- mechanical rotation angle 290 +-5 degrees
Applications For Rheostats
The APR series rheostats have been used in literally hundreds of including;
- motor control – a.c. and d.c.
- lighting control circuitry
- laboratory test equipment
- battery testers
- portable power supplies
- heating control circuits
