PSV-D driver module

Pulse width modulated PSV-D driver modules regulate the power supplied to PSV proportional electromagnetic valves based on a reference signal. Set-point signals, 0 - 5 Vdc or 4 - 20 mA, input are employed to control the output pulse width modulated voltage at a fixed frequency (≈30KHz) and amplitude. Incoming power to the valve coil is applied and discontinued for predetermined periods of time by a low loss solid state switching element.

As incoming power is applied, energy in the inductive coils increases and when it is discontinued energy stored in the coil maintains the magnetic flux level required to hold flow at the controlled rate. This cycle takes place many thousands of times per second.

The wide range of power input feature conveniently accommodates 12 to 32 Vdc sources.

The Auto-Select feature of the Driver Module recognizes the type of reference signal received and defaults to 0 - 5 Vdc if both signals are provided.

Jumper selectable output power allows a choice of dc voltage range for cooler more efficient operation, as a function of flow rates.

Internal resettable fuse protects electronics and rectifier circuits, prevents polarity reversal damage.

The maximum output voltage supplied to the PSV Valve can be set or changed in the field to allow for optimal use of the input reference signal to output voltage based on the specific flowrate and operating pressure applied to the valve.

PSV valve and PSV-D driver module sold separately.
