Product Description:
The VT-NE31-13 belongs to the VT-NE Power Supply Units series manufactured by Bosch Rexroth Indramat. Designed as a compact bipolar supply, it delivers isolated positive and negative rails for analog control cards and proportional valve electronics in industrial automation systems. By converting standard mains power into regulated low-voltage DC, the unit supports sensor excitation, reference signals, and repeatable control behavior inside cabinets under varying loads.
The supply operates on 115/230 VAC ±10% at 50/60 Hz, rectifying and filtering the input before presenting two stabilized outputs. Under full load, the positive rail holds at +24 VDC and the complementary rail at -24 VDC; each channel can deliver up to 6 W without exceeding thermal limits. Continuous current is limited to 0.25 A, which helps downstream circuits maintain consistent voltage when the AC line fluctuates.
Input overcurrent is blocked by a 0.8 A slow-blow fuse, and no-load testing shows a center voltage of ±27 VDC to provide transient headroom at startup. Residual ripple stays below less than 5%, preserving signal integrity on sensitive analog stages and helping reference values remain clean. Cabinet mounting follows the DIN rail profile EN 60715, and the housing also accepts 4 mm² wiring for orderly panel layout.
Wake Industrial can arrange same-day shipping for urgent orders, and each unit carries a 1-year warranty. Formal quotes remain valid for 30 days, which helps maintenance teams coordinate purchasing without delay.
