Product Overview

The SE‑3000 series 3000W enclosed switching power supply is a heavy‑duty high‑power AC‑DC conversion unit engineered for demanding industrial environments, battery‑charging integration, OEM equipment embedding and large‑scale commercial power projects. Built to deliver consistent, reliable DC power under continuous full‑load conditions, this power supply accepts wide‑range single‑phase AC mains input and outputs stabilized direct‑current voltage across a broad selection of standard preset options, alongside flexible custom‑voltage OEM support.

Core Electrical Performance

Rated for continuous 3000W total output power, this power supply features an input range of AC 185‑265V, compatible with most global single‑phase commercial and industrial grid power. The wide‑voltage input tolerance allows stable operation amid common mains voltage fluctuations, voltage sags and minor grid noise, reducing downtime risk for your finished equipment.

Output DC voltage portfolio covers a comprehensive selection to match diverse project requirements:

– Main standard voltages: DC12V, DC24V, DC36V, DC48V, DC60V, DC72V

– Intermediate special‑purpose voltages: 13.8V, 15V, 18V, 21V, 27V, 28V, 30V, 32V, 42V, 70V

– High‑voltage output group: DC80V, DC90V, DC100V, DC110V, DC120V

– Custom development: Non‑standard special DC output voltages can be developed upon OEM bulk‑order requests.

The unit adopts high‑efficiency switching circuit topology, delivering high energy conversion efficiency and low output ripple noise. Low ripple output protects sensitive downstream loads, battery cells and circuit boards from high‑frequency interference, which is especially critical for battery‑charging applications, as excessive ripple will accelerate battery ageing and shorten overall cycle life. It maintains stable voltage output even when facing dynamic load changes, which is common for motor‑driven equipment and variable‑current battery charging cycles.

Mechanical Structure

Housed in a rugged black metal steel enclosure, the SE‑3000 series is built for industrial‑grade durability. Large‑area honeycomb ventilation perforations are arranged on the housing side panels to maximize natural air convection flow across internal power components. The optimized ventilation layout facilitates effective heat dissipation during long‑hour full‑power operation, preventing internal component overheating under normal working ambient conditions.

Clear printed labels are pasted on the outer shell, marking input‑output terminals, safety warnings and core specification information, helping your technical team complete wiring and commissioning quickly and correctly.

Comprehensive Multi‑Layer Protection Mechanisms

Built‑in complete safety protection circuits are integrated into the SE‑3000 power supply, to safeguard both the power unit itself and your expensive downstream loads. The protection suite includes over‑voltage protection, over‑current protection, short‑circuit protection and over‑temperature protection.
