High power rheostat
max. 240 kΩ, 1 500 - 7 000 W | STV - SQV series COUDOINT S.A.S.

The Coudoint STV and SQV High Power Rheostats are characterized by:
- ohmic values from 0,74 Ω to 60 kΩ
- power ratings from 1.5 to 7 kilowatts
with numerous possibilities : DC, AC single-phase or 3-phase rheostat or variable load, with manual or motorized slider drive, use of rheostats assemblies for achieving higher power ratings, etc.

These rheostats are constructed of 3 (STV Series) or 4 (STV Series) wirewound cylinders, with 4 cylinder sizes:
- STV1 (1500 W), STV2 (2500 W), STV3 (3750 W), STV4 (5250 W)
- SQV1 (2000 W), SQV2 (3330 W), SQV3 (5000 W), SQV4 (7000 W)

These products, which we have been providing for decades, have proven their quality and durability time and again, with:
- windings made of low-temperature coefficient resistance wire to insure the best stability of the ohmic value
- slider mechanisms optimized to provide a smooth motion and a high resistance to wear (durability)
- numerous options available: type of terminal connections, graded or Ayrton-Perry windings, manual or motorized slider drive, etc.

Each rheostat is built at the required ohmic value, in the range of feasible values. Using various connection diagrams, the product can be wired as a single variable load or a rheostat with high current capability, or as a three-phase load or rheostat: See our "Sliding Rheostat" technical documentation for more details.

Special models can be designed for specific needs.
