ECU1/ECU2 Series

Up to 50 % energy savings. Contributes to reduced CO2 emissions and lower running costs.

Ecology Simulation

This tool simulates the reduction in running costs, such as power consumption, CO2 emissions using the ECU Series as compared to your servopulser hydraulic power supply unit.

Do you know how much electric power your hydraulic power supply unit consumes?

A conventional hydraulic power supply unit for fatigue and endurance testing machines runs continuously at full power to be able to generate the maximum test force and test speed at any time. As the hydraulic power supply unit is selected to provide the maximum capacity for the expected testing, the power consumption may be excessive under some test conditions.

Installing an Eco Unit can cut power consumption by up to approximately 50 %*!

The Eco Unit reduces the power from the hydraulic power supply unit according to the test conditions and circumstances to save energy.

The hydraulic power supply unit runs at reduced power in standby status.

* For ECU2 in 60 Hz area. (Max. 30 % for ECU1.)

Power Savings with Energy-Saving Operation

■ Retrofit to existing hydraulic power supply units

An Eco Unit can be retrofitted to an existing QF-A/QF-B/AF Series hydraulic power supply unit.

(A model 4830 servo controller is required to set energy-saving operation.)

■ Remote operation

Energy-saving settings (motor set frequency and supply pressure) for the hydraulic power supply unit can be set from the model 4830 servo controller or Windows software. (Patent pending)

■ Optimal energy-saving operation performed automatically

If the Windows software is used with the Eco Unit, the optimal energy-saving operation can be performed automatically according to the test conditions and circumstances. It ensures effective energy-saving operation while performing the target testing.

Energy-saving operation suppresses the noise and heat generation from the hydraulic power supply unit.


4830 Servo Controller


■ Push test function for testing actual objects
Allows stable peak-value control using the test force, even for specimens with "play" (areas where no test force is applied).

■ Enhanced stability
Features overload prevention for manual operation and upthrust prevention that works when a hydraulic power supply unit starts up (automatically sets control error to zero).

■ Superb operability
The test conditions can be set on a touch panel or jog dial.
Test conditions including test frequency, test force, and displacement can be changed at any time during the test.
Intuitive screen displays allow operation without referring to the manual.

■ Highly versatile
Allows synchronous control of up to four testing machines (actuators).
Diverse waveform displays, including X-T, X-Y, and peak graphs. USB connection to a computer permits various test settings and advanced data acquisition.
