Heitz Sprint 3 Machine Specifications

INTERMITTENT DUTY TORQUE, at any speed to 1200 degrees/second = 60 Nm.

CONTINUOUS DUTY TORQUE, at any speed to 2000 degrees/second:

25 Nm average or RMS. (Peak torque for continuous sinusoidal operation = 30 Nm). 

TORQUE MEASUREMENT
To 100 Nm at 2 percent linearity, no damage limit. Analog output scale is user-adjustable.

Standard output scale is ±1.00V / ±10.0 Nm.  (maximum ±10.0V) 

ANGLE MEASUREMENT
Resolution: 0.025 degrees, 16‑bit D/A. Standard scale is ±1.00V / ±100 degrees. Maximum allowable steer angle is ±819.2 degrees, including any overshoot. Recommended maximum angle command is ±720 degrees.

POWER
Input power is 9 to 18 volts from the vehicle's battery/alternator, which is used to maintain a 13.6 volt charge on system batteries through isolating regulated DC/DC converters. System has five 12‑volt, 5 amp‑hour lead‑acid batteries connected in series for 60 volts at the power amplifier when the servo is energized; and an additional 12 volt, 5 amp‑hour battery for miscellaneous system use.

With the system energized, the maximum current draw from the vehicle is 8 amps since additional current is supplied by the batteries.

The DC-DC converters isolate the system from the vehicle battery/alternator system, to prevent accidental ground loops.

The system is protected from reversed connection and alternator load dump transients
