Analog amplifier

Type VT 3000

Component series 3X

RE 29935/10.12

Replaces: 11.06

Overview of contents

Features

–  Suitable for the control of pilot operated proportional direc-

tional valves (type .WRZ, up to component series 6X) and 
direct operated proportional pressure valves (type DBEP6 
and 3DREP6, each component series 1X) without electrical 
position feedback

–  Four command values adjustable with potentiometers
–  Four command value call-ups with LED display
–  Differential input
–  Step function generator
–  Ramp generator
–  Two pulsed current output stages
–  Polarity protection for the voltage supply

Note:

When supplied the amplifiers have a ramp time of 5 s (setting 
of the ramp time of 1 s see page 6).
