Open Loop Control Type Driver

Controls proportional solenoid control valves with open loop control systems. Features a response time adjustment function which can change the pressure output without inducing shock.

[Features]
· Its constant current characteristics ensures that it suffers virtually no fluctuations in output current due to rises in solenoid temperature or fluctuations in the power supply voltage.
· The output current waveform (dither frequency and amplitude) is configured so that the hysteresis and resolution of the proportional solenoid control valve are at the most favorable settings.
· Current is controlled via the PWM (pulse width modulation) method, which helps minimize the generation of heat from the driver.
· Features functionality (response time adjustment function) for gradually changing the output current in relation to changes in the stepwise command input. This enables shockless changing of the oil pressure output (start-up and shut-down can be adjusted independently.)
