Danfoss MCE127A1000 Proportional Amplifier

is indispensable for driving hydrostatic transmissions outfitted with proportional magnets, whether supplied by 12V or 24V DC. It can drive power loads from 40mA up to 1.6A, and it boasts both short-circuit and reverse polarity protection, so you can use it with confidence. It also has diagnostics, indicated by LEDs, to show the power supply and valve power status.

The MCE127A1000 is highly customizable. You can independently adjust the minimum and maximum output current, set the ramp time, and even adjust the operating frequency so that it works seamlessly with your specific proportional valve.

THEORY OF OPERATION
S00927
The MCE127A1000 Proportional Amplifier allows the
independent adjustment of the minimum output current
I
MIN
and the maximum output current I
MAX
.
The ramp time t
UP
and t
DOWN
are adjustable independently
also.
The external setpoint potentiometer sets the output
current.
The operation frequency (standard 100Hz) is adjustable
to tune the amplifier for a special valve.
Two diagnostic LEDs show the presense of power
supply and the status of the output stage.
