The HDD Dual Coil PWM valve driver has been designed specifically to be an Apitech/Parker VPL compatible Valve driver.

 

Features of the HD Series Valve Driver:

  1. Easy to stock, easy to apply and cost effective. 

  2. Solid potted design assures reliable performance on harshest applications. 

  3. Multiple input types assure you meet application requirements. 

  4. 33 Hz & 75 Hz available

  5. This is one of many of the ultra-rugged, field proven electro-hydraulic solutions available from your electro-hydraulic systems partner—HCT.

Design Features of the HDD Dual Coil Digital Valve Driver:

 

Rugged Construction:

¨        Power Supply input is protected against automotive spikes.

¨        Epoxy potting provides mechanical protection and environmental resistance, including sealing potentiometers against moisture.

Setup and Installation:

¨        Hookup is through an 10-position terminal strip that will accept up to 12-gauge wire.

¨        Labels located next to each of the potentiometers and terminal strip connections simplify hook up and adjustment.

¨        A PWM% indicator LED turns from red to green as the output current goes from zero to maximum.

¨        Minimum input response (dead band elimination), maximum input response, ramp times, PWM can be adjusted with 10-turn potentiometers for precise control. 

Control Inputs:

¨        Accepts control inputs of -5V to +5V, 0 to +10V,  0 to 20 mA, 4 to 20 mA or an external potentiometer. Note:  An external potentiometer and knob are supplied with every unit.

Power Supply:

¨        Power supply voltage range is from 11 to 30 volts. (12 or 24 Volt Systems)

¨        Red power LED indicates sufficient power present for proper operation.

¨        The coil can be driven to within 1.0 volt of the power supply voltage at maximum current.  Note:  Some 10-volt coils require up to 13 volts for full valve shift when hot, making this an important feature for mobile systems.

Current Capabilities:

¨        The HDD Series can drive coils with requirements up to 3.5 amps.

Supplied with:

-        10K Ohm, 10-turn potentiometer and knob

Options Available:

¨        "Q" Option, Weatherpack Connectors with 6-inch leads.  See Order Guide for details.

¨        "V" Option, Single-turn waterproof potentiometer with bezel marked 0 to 100.  See Order Guide for details.

Environmental:

·        Operating Temperature:  -20 Celsius to +60 Celsius
