Enfield Technologies PWM Valve Driver D1

Description
The D1 PWM Valve Driver is designed specifically to drive and manage Enfield Technologies proportional valves. It converts a proportional command voltage into a -1.1…1.1A current signal to drive the valve’s linear force motor (different from a solenoid valve). Its on board electronics allow the flow characteristics of the valve to be easily adjusted for optimal performance. The D1 provides a readily available solution that is compact and easy to implement. The D1 helps users avoid the effort and experience of characterizing valves and developing electronics for their application. For applications using PLCs or computers, the D1 easily interfaces with the valve. This eliminates the need to write valve management routines which consume valuable processing cycles needed for other machine functions. The D1 has user-selectable settings for command signal input:0..5 or 0..10 Vdc. In addition, the D1 also accepts PWM signals with frequencies greater then 2kHz. With a wide range of power supplies accepted, 12 or 24 Vdc, the D1 can accommodate different user requirements. Thanks to the digital closed loop current control implemented by software the D1 can efficiently compensate for different types of perturbations, like change i the input voltage and change in the coll resistance due to temperature. Features: Low cost Small size Short circuit protection High efficient design LED indicators Adjustable valve dead band Adjustable dither amplitude Adjustable current maximum
