Controller Hydraulic Power Source Unit Electric-Hydraulic Servopulser Series

Lower Running Costs
Up to 50 % Using the ECU energy-conservation unit enables an energy-saving mode that can switch OFF the hydraulic power supply unit power depending
Lower Power on the testing parameters and testing status. It also reduces the hydraulic power supply unit's power level when tests are in standby mode.
Consumption
Note: When using the ECU2 in a region with 60 Hz power supply (up to 30 % when using the ECU1).

Automatically Sets the Optimal Energy-Saving Mode
Automatic Used in combination with Microsoft Windows software, the ECU unit can automatically set the optimal energy-saving mode based on test
Energy-Saving parameters or testing status. This ef ciently reduces operating power consumption while continuing to perform intended tests.
Operation
Operation with a Hand-Held Controller
The unit can be operated with a hand-held controller.
The hydraulic power supply unit's energy-saving settings (motor frequency and supply pressure settings) can be set from the Servo
Remote Controller 4830 or from Windows software for 4830.
Operation
Lower Hydraulic Power Supply Unit Operating Noise and Heat Generation

The energy-saving mode reduces the operating noise and heat generated from the hydraulic power supply unit. It also reduces heat
generated from the oil, which helps extend the life of the oil.

ECU Units Can Be Retro tted on Existing Hydraulic Power Supply Units
(QF-A, QF-B, and AF Series)
Notes
For systems using a controller model prior to the Servo Controller 4830, an ECU controller is required.
Retro tting an ECU unit on an existing system requires an on-site survey of the system in advance.
ECU Controller It may not be possible to retro t an ECU unit on existing hydraulic power supply units in poor site conditions.
