PWM Controlled Solenoid Driver

The PWM Controlled Solenoid Driver supplies a proportional solenoid with current proportional to a digital pulse width modulated (PWM) input signal of 250 to 5000 Hz (5-95%). It accepts power supply voltages from 9 to 32 VDC. This linear solenoid driver utilizes high frequency switching output (PWM) to provide a DC current output of 2 Amps (1.2A available). A current sensing circuit maintains output current regardless of changes in input voltage and coil resistance. The user can adjust the zero setting, maximum output current, dither frequency and dither level as well as independent rising and falling ramps to suit their application. A system of LED's indicates output power level, input level and power on/off. The unit is available as a stand alone PCB Board or as a Packaged Driver enclosed in an IP67 rated metal housing with 1.5 m (5 ft.) of cable. The circuit board is conformal coated. The metal box or PCB are designed for remote mounting. A DIN rail mount version is also available. The metal box and DIN rail versions comply with CE directives for EMC.
