Industrial 12 V 400 W power supply

This myVolts unit delivers a regulated DC 12 V output at up to 33 A for 400 W total power. It is built for industrial automation, LED displays, CCTV systems, 3D printers and similar fixed-installation loads that require a steady 12 V rail.

Verify input voltage and wiring before ordering

The supply accepts AC 110 V or 220 V with a ±15 % tolerance, so confirm your mains voltage falls within that range. You must also provide a suitable enclosure and make the L, N, GND, V and ADJ connections yourself, as the unit ships as an open-frame module without a mains lead or output plug.

Protection features and voltage adjustment

Built-in short-circuit, overload and over-voltage protection shut the output down under fault conditions. The +V/ADJ terminal lets you trim the output voltage slightly, while the aluminium chassis relies on natural convection cooling within the 0–40 °C operating window.

أسئلة حول هذا المنتج

What comes in the box with the S-400-12 and what must be purchased separately?

The unit ships as a bare open-frame supply with screw terminals for L, N, GND, V and +V/ADJ. No IEC cable, mounting brackets or DIN-rail clips are included; those must be sourced separately.

The comparison table lists S-36-12, S-50-12 and S-400-12; how do I decide which model fits my load?

Match the continuous draw of your device to the output current: 3 A for 36 W loads, 4.2 A for 50 W loads, or 33 A for 400 W loads. Choose the model whose current rating exceeds your peak demand with headroom.

What does the 400 W rating mean when the supply is installed in a 3D printer or CCTV cabinet running at 40 °C?

At the maximum rated ambient temperature of 40 °C the unit can continuously deliver 12 V at 33 A (400 W) provided airflow meets the natural-convection design; higher enclosure temperatures will reduce available power.
