Description
Electronic dual-channel amplifiers are 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 SU-A2.1 dual-channel electronic amplifier is intended for controlling swash plate pumps with proportional electric control, valves, and pilots with proportional control and proportional solenoids.
It is used in hydraulic control systems.
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 dual-channel electronic amplifier can be used in systems with most proportional hydraulic machines and distributors.
