Product Description:
The VT-NE31-15 is a compact bipolar power supply unit from Bosch Rexroth Indramat’s VT-NE Power Supply Units series. It converts single-phase mains into two regulated DC rails for proportional valve amplifiers, sensor bridges, and other low-power control electronics. Its dual-output design supports stable reference voltages in hydraulic and motion-control cabinets while using little DIN-rail space.
The primary is preset to 230 VAC, so standard operation on that mains level requires no internal adjustment. An internal 0.8 A slow-blow fuse protects the transformer during startup, and the input also accepts 50/60 Hz line frequency for use across common utility standards. With no load connected, the regulator provides symmetrical rails of +27 VDC and -27 VDC, giving downstream circuits headroom before normal operating demand pulls the voltage lower.
Under rated conditions, the unit supplies filtered outputs of +24 VDC and -24 VDC. Each rail can deliver up to 0.25 A, which is suitable for low-power analog loads that need steady bipolar supply voltage. Residual ripple stays within less than 5%, helping limit electrical noise in sensitive stages. Screw mounting or EN 60715 DIN-rail mounting allows flexible panel placement, and the terminal strip accepts 4 mm² conductors while the 1.1 kg weight keeps cabinet loading modest.
