-2X: Design series

The EAS-D24-A-2X Series amplifier for standard rail mount, used to drive a single solenoid proportional valve. Amplifier calibration valve adjustment, so that the input signal corresponds to the electromagnetic proportional valve to provide the required current. The amplifier is used for open-loop control system. Amplifier by switching current on the electromagnet, the valve to adjust the input signal (voltage or current) is proportional to, In order to guarantee the accuracy of the valve adjustment, available on the amplifier potentiometer to adjust the gain and bias.

Supply amplifier input signal is usually provided by an external potentiometer or PLC control unit. By the ramp generator, the amplifier bias current adjustment, gain adjustment, PWM modulation to enable control and protection circuit, the current adjustment range 0-3 security, load impedance, 2 - 45Q, and the proportion of the ATOS governor valves, proportional pressure valve is best match use.

Bias adjustment:
Dead band adjustment of the valve of the hydraulic zero electrical zero position corresponds to have the output current when the input voltage is equal to or greater than 115mv.

Ramp time to adjust:
Internal ramp generator circuit will step input signals are converted to slow increase output
(electromagnet current) from 0 to 10 v rise for the longest time for 20 seconds.

Flutter frequency adjustment:
Flutter frequency adjustment in the 100 - 500Hz range

Note that things top:
Push-pull amplifier can not be charged; power near-line string 1A insurance to protect the amplifier; amplifier for the open system, equipped with proportional valve should not work in the limit state.
