The VT-NE Power Supply Units series is a family of compact power supply units for electrohydraulic control systems, intended to supply amplifier electronics for proportional and servo valves as well as related control components.
The series includes unipolar and bipolar output versions, with the VT-NE30 used for proportional valve amplifier supply, the VT-NE31 configured for servo-valve amplifier supply, and the VT-NE32 adding a regulated output for closed-loop and evaluation electronics such as pressure transducers and position-measurement devices. These units operate from 115 VAC or 230 VAC at 50/60 Hz and use terminal-strip connections in a housing that can be screw-mounted or snapped onto EN 60715 top-hat rail. Output design across the series combines filtered supply voltages with miniature-fuse short-circuit protection, while the VT-NE32 also includes overload or short-circuit shutdown of the regulated output with manual reset. LED indication and compact mechanical dimensions make the VT-NE series suited for cabinet installations where hydraulic amplifier supply and auxiliary control voltage need to be combined in a small footprint.
