PVD3D1N Proportional Valve Driver

Product catalog summary

Product Overview: The PVD3D1N is a proportional valve driver from PWM Controls Inc., designed for versatile digital control of one PWM solenoid output. It features a sealed plastic enclosure and is equipped with a large, easy-to-use three-digit seven-segment LED display.

Benefits and Features: The device offers a wide range of supply voltage, electronic limiting circuit, and short circuit protection. It allows live connection and disconnection of loads and is protected against incorrect connections. The energy-efficient PWM circuit eliminates the need for a heat sink, and current sensing ensures consistent output despite changes in supply voltage and coil resistance.

Specifications: Operating voltage ranges from 9 to 35VDC, with a maximum output current of 3A. The ramp time is adjustable from 0.0 to 99.5 seconds, and the linearity is 0.5%. The PWM/dither frequency ranges from 50 to 500Hz, and it operates in temperatures from -40° to +75° Celsius. It complies with EMC Directive 2004/108/EC standards.

Control and Input: The device supports simple control with analog input, with locally supplied reference voltage. It includes three PG7 liquid-tight cable glands for power, signals, and coil connections. Input signals are user-selectable among 0-5V, 0-10V, 0-20mA, or 4-20mA.

Settings and Range: Users can adjust settings such as output current (H1, J9, LO), ramp times (UP, dn), deadband (db), dither frequency (df), input signal selection (in), and display orientation (di). Settings are saved by rotating the control until 'SA' is displayed and then rotating one full turn.

Setup Procedure: The driver remains fully functional during setup, with immediate effect of adjustments except for input range selection, which requires saving. To save new settings, rotate the control to 'SA' and perform a full turn. Powering down without saving will discard changes.

Wiring Diagrams: The document includes wiring diagrams for connections with an analogue card/PLC, potentiometer/joystick, and a switch for soft shifting between two presets.
