a)
All -5N(A) dynamometers are 5 Volt Output. Contact Magtrol for 6N (English), 7N (Metric) and 8N (SI) Specifications.
b)
Note: Operating at the continuous power rating for periods of up to 4 hours is acceptable. However, operating for extended periods at high temperatures will
result in premature component and bearing failure. Limiting the length of the cycle and the component temperatures will guard against premature failure. Where
continuous duty is desired for longer time intervals, component temperatures should be maintained less than 100°C; monitoring the outside brake surface
temperature is a sufficient reference.
c)
Requires air cooling provided by user. Regulator and filter package is provided as standard equipment on these units.

c)
The maximum speed will depend on what type of keyway (if any) is used on the shaft. Unless specified, the dynamometer shaft will be made without a keyway.
