Product Description:

The VT-NE31-19 is a compact bipolar power supply unit manufactured by Bosch Rexroth Indramat within the VT-NE Power Supply Units series. It is designed for control cabinets and servo electronics that require isolated positive and negative rails for analog circuits or valve amplifiers. Because the output rails are isolated from the input side, the unit helps protect sensitive signal stages from supply disturbances elsewhere in the cabinet. That arrangement helps maintain stable reference voltages in industrial automation environments.

This model accepts an input of 230 VAC ±10% or 115 VAC ±10% at a line frequency of 50/60 Hz. A front-mounted 0.8 A slow-blow fuse protects the primary winding, and internal regulation limits the secondary side to a maximum load current of 0.25 A. Screw terminals accept conductors up to 4 mm², and the enclosure measures 84 mm wide, 119.5 mm high, and 70 mm deep while weighing 1.1 kg.

Differential outputs provide +24 VDC and -24 VDC for symmetric low-power circuits. Each winding is filtered to keep residual noise below <5%, which supports stable analog performance and reduces the need for extra external filtering. The fully filtered design also noticeably lowers external component count inside compact assemblies. Each rail is rated for 6 W, allowing both channels to be loaded at the same time without cross-regulation problems.
