*Absorber
capacities are RPM dependant. Air-cooled absorber loads are rotor temperature
dependant. Water brakes require a minimum water flow of 1 gpm @ 30+ psi for every 20 continuous Hp.

60-Hz AC, 240-volt 50-Hz AC, or 12-volt DC
“Pro” PC based 28, 56 or
112+ channel capable board sets, require DYNO-MAX software
“Lite” 3-channel
(upgradeable to “Pro” above)
Up to 1,000 recordings per second (per channel)
Quick disconnect data harness

Hp Capacity** (traction
limited):
** Approximate; limited primarily by
tire safety and traction - higher torque transfer requires tie downs. Continuous
capacities depend on selected absorber and test speed.

absorber)

absorber)

single eddy absorber)
