SE-3000 : 3000W AC to DC Adjustable Voltage and Current Switching Power Supply

The WEHO SE-4000 is a formidable single-output switching power supply engineered to output a massive 4000W. Built to operate reliably across 180-264VAC or 245-370VDC input ranges , this series provides a comprehensive selection of DC voltages from 12V up to 220V. It features a sophisticated dual-control architecture, empowering users to dynamically manage both voltage and current outputs using either a 0-5V/0-10V analog voltage signal or a manual external potentiometer. With peak efficiency ratings reaching 91% , it also integrates a 12V 0.5A auxiliary power supply and a dedicated remote control switch. The system is securely housed in a 300 x 200 x 70mm chassis weighing 4.1kg

Description

Summary

Single output: Power 3000W

Input voltage: 180~ 264VAC/245-370VDC

Core Advantages & Application Scenarios

Core Advantages

Extreme Power Density: Safely delivers up to 233.3A of current on the 12V model without compromising stability, achieving a precise ±1.0% voltage accuracy.

Intelligent Fault Recovery: Features proactive over-temperature protection that automatically shuts down the output and seamlessly restarts once the temperature normalizes, drastically minimizing maintenance.

Advanced Control Integration: The 0-5V/0-10V analog adjustability combined with the default-on remote control switch allows for frictionless integration into centralized PLC logic networks.

Application Scenarios

EV & Battery Infrastructure: The robust constant current capabilities make it the perfect backbone for high-capacity electric vehicle charging stations and large-scale battery forming facilities.

Industrial Heating & Metallurgy: Supplies the unyielding 4000W continuous output necessary for industrial electric heating furnaces and heavy electrolysis processes.

Centralized Telecom Hubs: Acts as a highly reliable, high-wattage primary power source for massive server farms and telecommunication arrays requiring steady DC input.
