Hp, Torque, and RPM Capacity:

*Actual air-cooled eddy current capacities are RPM and absorber temperature dependent. Initial cold rotor torque and Hp capacities are approximately twice the hot rotor Hp capacities shown below (taken after running 10 minutes, at full load, in a room temperature environment). Continuous ratings will be approximately 50% of these hot values.
“Micro” up to 1 Hp hot (¼ Hp min.)*
“Mini” up to 3 Hp hot (¾ Hp min.)*
#20 up to 20 Hp hot *
#100 up to 100 Hp hot *
#150 up to 150 Hp hot *
#200 up to 200 Hp hot *
#300 up to 300 Hp hot *
#400 up to 400 Hp hot *
#650 up to 650 Hp hot *
AC & water cooled eddy current (call)
Hp options range from ¼ to over 10,000
Torque options from ¼ to over 5,000 lb-ft
RPM options from 500 to over 30,000

Engine Tachometer:

0 - 32,000+ RPM LCD display
