Control Solenoïd Valve Proportionally w/166Hz PWM

[QUOTE="Charly Segaert, post: 5727939, member: 615412"] Hello everyone, I have to control a solenoïd valve proportionally using a 166Hz PWM signal. The resistance of the coil is 2,5-4 ohm. If i'd be using a pure DC signal I'd have around 8 amps of power. However this is an oscillating signal. Since a coil resists changes in current, the effective current will be higher I guess? I want to create this signal using a digital output in Labview. The problem is that I can only draw a few milliamps from the output. Is it sufficiënt to intensify the signal using a transistor or mosfet? Or do I need to find a complete printed circuit with filters,...? Thanks for your answer [/QUOTE]
