SE-4000 : 4000W AC to DC Adjustable Voltage and Current Switching Power Supply

Engineered for maximum performance, the WEHO SE-4000 is an elite single-output switching power supply built to drive power-hungry industrial applications. Delivering a massive 4000W of power , it operates safely on a 180-264VAC or 245-370VDC input and offers a versatile range of DC outputs from 12V up to 220V. This series distinguishes itself with a highly adaptable control interface, allowing operators to precisely adjust output voltage and current utilizing either a 0-5V/0-10V analog signal or an external potentiometer. Boasting an energy conversion efficiency of up to 91% , the SE-4000 also features an integrated 12V/0.5A auxiliary power source and remote switching capabilities , all housed in a rugged 300 x 200 x 70 mm chassis weighing 4.1kg.

Paglalarawan

Buod

Single output: Power 4000w

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

Competitive Advantages

Dual-Signal Programmability: Seamlessly integrates into automated IoT and PLC networks via 0-10V analog voltage control , while retaining manual external potentiometer support for flexible, real-time tuning on the factory floor.

Autonomous Thermal Recovery: Designed for uninterrupted 24/7 reliability, its intelligent thermal defense automatically shuts down the output during extreme heat spikes and autonomously re-engages once cooled, ensuring true zero-touch maintenance.

Active Short Circuit Defense: Instead of immediate failure or blown fuses, the power supply intelligently shifts into a constant current mode during a short circuit, preventing catastrophic electrical surges to your highly sensitive 4000W equipment.

Streamlined Control Architecture: The built-in 12V/0.5A auxiliary output and default-on remote control switch eliminate the need to purchase and wire secondary power adapters, saving crucial space and labor in complex OEM control cabinets.
