Product Details

Hawei EV22K2-12/24 amplifier board original supply

The characteristics of Hawei products are that the valve body is a fully rigid structure, resistant to high pressure, compact in structure, small in volume, leak free, and has a long service life. It is widely used in industries such as engineering machinery, machine tools, ships, metallurgy, hydraulic tools, etc.

The EV type proportional amplifier can be used as a module for mounting rails or as an optional card for clamps. The measurement of current backflow output through valves can demonstrate extremely accurate functionality.

With the help of additional clips, the EV1M3 proportional amplifier can be installed on 32mm or 35mm rails.

Through precise adjustment and high-precision current backflow measurement, even demanding hydraulic applications can be easily achieved.

The adjustment of valve parameters such as background current and maximum current, vibration, and slope can all be achieved through multi turn potentiometers.

The control parameters (minimum current, maximum current, flutter current, ramp time) can be adjusted through buttons or potentiometers.

The configuration components of the Hawei amplifier board“

A power supply with reverse power protection, used for various functional components, and a short-circuit resistant voltage regulator used to generate a regulated power supply of 5DC or 10VDC

Analog adder, used for adding and subtracting voltages from the reference voltage

Equipped with a ramp generator that allows for separate setting of rise and fall times

Vibration generator with cutting function and adjustable vibration amplitude

A current regulator with broken wire indication, stage regulation, and final stage short-circuit resistance

Digital microcontroller indicates current input, operating status, and fault monitoring

The advantage of Hawei's enlarged board

A device can provide 12VDC and 24VDC power supply

Reverse protection of current source

Two stable voltages, 5VDC and 10VDC, and a reference voltage are available for selection

By using a multi turn potentiometer, the basic and maximum current can be accurately adjusted in two directions

Accurately maintain the rated current

The flutter signal is superimposed on the output current

The vibration amplitude value is adjustable, and the vibration frequency is about 55Hz

Use a multi turn potentiometer to adjust the increasing and decreasing ramp time

Hawei EV22K2-12/24 amplifier board original supply

EV22K2-12/24 is used for controlling proportional valves with a housing structure. This amplifier from Hawei has a good price performance ratio and is small in size, making it suitable for operating proportional valves with single proportional electromagnets.
