General

The S Series is a family of single-output switching power supply designed for a wide range of industrial applications. With models ranging from 25W to 400W, these power supplies offer reliable AC-to-DC conversion, supporting input voltages of 115VAC or 230VAC (selectable via a switch for models from 50W to 350W). Output voltages include 5V, 12V, 15V, 24V, 36V, and 48V, providing flexibility for various system requirements.

Built with efficiency and durability in mind, the S Series achieves up to 89% efficiency and features forced air cooling via a built-in DC fan to ensure stable operation even under full load. The series supports a wide operating temperature range from -25°C to +70°C and can operate at altitudes up to 5000 meters, making it suitable for demanding environments.

Comprehensive protection circuits are included for short circuit, overload, and over voltage conditions. Each unit undergoes 100% full-load burn-in testing to guarantee reliability. With low no-load power consumption (<0.75W) and compliance with international safety standards (such as IEC/UL 60950-1), the S Series delivers a high price-to-performance solution for industrial automation, control systems, machinery, and electronic equipment.
