Digital Plug Amplifier for Proportional valves – PES-XD
The PES-XD amplifier is a digital amplifier to control proportional valves.
The unit supplies a variable current proportionally to the setpoint signal and independently of temperature variations or load impedance. It has a resolution of 1% on 2600 mA (full-scale value).
The PWM stage on the solenoid power supply makes it possible to reduce the valve hysteresis thus optimising control precision. The amplifier is customizable with different maximum current sizes and switching frequencies (PWM). Therefore, their control depends on their optimisation according to the valve.
Moreover, a setting is possible by buttons and display inside the case, or with a notebook by RS232 with the software for PES-XD.
