Product Description:

The VT-NE31-11 is a compact bipolar power supply unit from Bosch Rexroth Indramat in the VT-NE Power Supply Units series. It converts single-phase input power into two regulated output rails for proportional valve amplifiers, command electronics, measuring circuits, and other low power analog modules in industrial cabinets. Isolated, filtered outputs help preserve stable operation when nearby drives, contactors, and switching devices introduce electrical noise.

The unit accepts 230 VAC ±10% or 115 VAC ±10%, selected by an internal tap, so it can be used in plants with either common service voltage. It operates on 50/60 Hz mains power, which supports straightforward integration into standard control panels without extra frequency conversion hardware. A 0.8 A slow-blow fuse limits fault current, and residual ripple stays at less than 5% under full load to protect sensitive analog circuits.

Each output rail can supply up to 0.25 A at nominal load, giving the module enough current for multiple low power control cards and sensors. Available output power reaches 6 W per channel, which helps the supply support analog electronics without excessive transformer heating in dense cabinet layouts. The positive rail is regulated at +24 VDC, and the negative rail is regulated at -24 VDC for balanced bipolar circuitry.

Wake Industrial stocks this unit and can arrange same-day shipping when required. Quotes remain valid for 30 days, which can help with purchasing schedules and maintenance planning.
