VT-NE32-13

The VT-NE32-13 is a compact, unipolar, regulated power supply unit manufactured by Bosch Rexroth Indramat for the VT-NE Power Supply Units series. It delivers two isolated DC rails that energize control electronics and proportional valve amplifiers in industrial automation racks. This electrical isolation allows each connected circuit to receive power without creating an unintended current path between the two outputs. Regulated operation keeps the supply voltage stable when demand from connected machine components changes during operation.

At full load, the first rail provides a maximum current of 2.5 A at +25 VDC. This channel can deliver up to 60 W of continuous power, allowing it to operate multiple compatible analog cards without excessive voltage drop. Residual ripple is limited to 2 % of the nominal voltage, reducing electrical noise that could interfere with low-level command and feedback signals. The internal architecture uses a dual-output design with filtering and closed-loop voltage control. Post-regulation capacitors suppress ripple, while a reference circuit continuously corrects the switching stage as the connected load changes. These control functions help prevent short-term current demand from causing unstable supply behavior in sensitive analog circuits.

The second rail supplies 1 A at +24 VDC for compatible digital input and output modules or small solenoid coils. Its rated capacity is 24 W, providing a separate source for lower-power devices that do not use the first output. Residual ripple on this rail does not exceed 50 mV AC, helping logic signals remain within their required switching thresholds during high-frequency operation. The unit has the internal series identifier 13 and weighs 2.2 kg. Its relatively low mass supports DIN-rail or back-panel mounting without additional bracing, while the enclosure provides sufficient thermal mass for stable use in enclosed industrial cabinets.
