Product Description:

The VT-NE31-16 is a compact bipolar power supply unit manufactured by Bosch Rexroth Indramat for the VT-NE Power Supply Units series. Installed on DIN rails or panel brackets, it bridges factory mains and low-voltage electronics by delivering balanced DC rails for signal conditioning, sensor excitation, and small actuator loads inside automated equipment. Its bipolar design supports control circuits that need both positive and negative rails from one enclosure. That arrangement can reduce the need for separate auxiliary supplies in compact cabinets.

The module accepts an input of 115/230 VAC ±10% at a line frequency of 50/60 Hz. Primary over-current protection is provided by a 0.8 A slow-blow fuse mounted on the front, helping limit damage during faults. After rectification and filtering, the circuitry provides a positive rail at +24 VDC and a mirrored negative rail at -24 VDC. Separate filtering on each rail helps suppress conducted noise that could interfere with downstream analog modules or motion controllers.

When no external load is connected, the unit stabilizes at ±27 VDC, ensuring reserve headroom once full-load conditions are applied. Continuous demand is limited to a maximum of 0.25 A, and residual ripple remains below < 5 %, which helps preserve stable reference signals for precision transducers. Output power is rated at 6 W per rail, making the unit appropriate for valve amplifiers and small PLC expansion cards.
