Product Description:

The VT-NE31-17 is a compact bipolar power supply unit produced by Bosch Rexroth Indramat within the VT-NE Power Supply Units series. It converts alternating mains power into balanced direct-current rails for electronic control cards used in hydraulic and motion-control racks. That function supports operational amplifiers, pilot valves, and sensor circuits in industrial automation.

The unit accepts 115/230 VAC ±10% at 50/60 Hz, allowing one model to serve North American and European panels without tap changes. Primary protection comes from a 0.8 A slow-blow fuse, which tolerates inrush current while opening during sustained overloads. Internal regulation provides +24 VDC and −24 VDC rails so connected analog cards receive balanced supply voltage.

During operation, the supply delivers a continuous total load of 0.25 A across both outputs, which equals 6 W per rail at full load. Residual ripple stays below <5%, helping limit noise that could disturb sensitive reference signals in nearby analog circuitry. The assembly weighs 1.1 kg, mounts with screws or on an EN 60715 rail, and uses separately filtered outputs to reduce coupling between the positive and negative channels.

Wake Industrial offers same-day shipping for urgent orders and applies a 1-year warranty to every unit sold. The chat tool available on the website can be used for questions about type codes or fault indicators. This supply suits racks that need stable bipolar output for low-power control electronics, and its compact form helps conserve panel space while keeping service replacement simple during maintenance in densely packed industrial control cabinet layouts.
