Control Qualities
Hysteresis is within three percent of maximum travel when measured over a full 42 degrees of travel. Hysteresis is within 0.5 percent of maximum travel when measured over four percent of full travel at 1 Hz.Temperature Drift ... Nominally 1 degree per 38°C (100°F)Time Constant is 96 to 116 mS for 50 mA step with 1172 kPa (170 psi) actuator oil pressure.Linearity is within 2.5 percent of full 42 degree output travel.Work Output is 38.9 J (28.8 lb ft) stalled torque; 28.6 J (20 lb ft) of work over 42 degrees. The actuator operates with 1172 kPa (170 psi) internal hydraulic pressure. Note: In older actuator models, work output was 24.3 J (18 lb ft).Pump type Gerotor (3161 pump). The relief valve is set at ... 1172 kPa (170 psi).Output Shaft "D" shaped shaft.Drive Shaft 0.625-36 serration is standard.Weight 16 kg (36 lbs) dry weightVibration Resistance Vibration tested to US MIL-STD 810C, Curve D (10 G to 2000 Hz; in Y-axis, parallel to drive shaft, 8 G maximum)Drive/Hydraulic Specifications
The actuator is available with either a high speed pump or a low speed pump. The high speed pump operates at 600 to 1500 rpm. The low speed pump operates at 375 to 1100 rpm. The actuator drive operates in one direction only.Drive Power Requirement Drive will use a maximum of ... 375 W (0.5 hp)Hydraulic Supply has a self contained sump, 1.4 liter (1.5 quart) capacity. In most cases, the same type of oil used in the engine can be used in the actuator.Ambient Temperature Range ... -29° to +93°C (-20° to +200°F)Operating Temperature ... -29° to 93°C (-20° to +200°F), within the limits of the oil being used in the actuator.Electrical Specifications
