Description
The single-channel electronic amplifier is designed to convert low-current control signals from control devices (control panels, joysticks, and pedals: 0…5 V, 0…10 V, 0…20 mA, 4…20 mA) into power PWM signals (0…3 A) for controlling one or two proportional solenoids.
The amplifier converts the low-current input control signal into a power PWM output signal for controlling a solenoid (electromagnet).
The amplifier is microprocessor-based. No special programming is required — configuration is carried out using three buttons located on the front panel.
Applications
-
Control of pumps and hydraulic motors with proportional electric control
-
Control of valves and pilots with proportional control and proportional solenoids in mobile and stationary installations
-
Control of valves and pilots with proportional control in complex electronic control systems, as well as direct control of a single solenoid
The single-channel electronic amplifier can be used in systems with most proportional hydraulic machines and distributors.
