Solenoid Controller optimizes valve performance
The 900R Solenoid Control Module, as developed
by pinch valve manufacturer Acro Associates, makes a solenoid
three to ten times more power efficient than with other
control techniques, a critical factor in battery-powered
applications. The 900R contains a low-side FET power switch
employing a pulse-width modulated (PWM) output, which
conserves energy and reduces waste-heat production. The
unit also features Acro's exclusive "adaptive" pulse
and hold technology, which facilitates higher forces,
longer strokes, and extended duty cycles by optimizing
power consumption. Integrated microprocessors analyze
load current for additional power savings and short-circuit
protection. The 900R provides up to 5A of drive current,
and the user interface consists of an opto-isolated differential
input port that can be directly wired to relays, transistor
logic, digital I/O boards and PLCs, for high-performance applications.
The solenoid controller reads continuous feedback from
position sensors and monitors faults, and through the embedded
circuitry in the driver, it is able to monitor and adjust to your
system's needs. The 900R is also protected against power reversal
on its supply pins. The driver's software is fully customizable
allowing for optimum use in the most unique applications.
