Product Description

Multiple Protection Functions

The product features comprehensive protection mechanisms, including short circuit, overload, and over-voltage protection. It automatically secures the system during abnormal loads and recovers once the fault is cleared, effectively extending equipment life and reducing maintenance costs.

Wide Input Voltage & Global Compatibility

High Reliability & Rigorous Quality Assurance

 It supports a wide range of AC input (85132VAC/170264VAC, selectable by switch), making it compatible with power grids in most countries and regions worldwide, meeting the demands of international industrial and commercial applications.

Each S-50 power supply undergoes 100% full-load high-temperature burn-in testing before leaving the factory. Its compact aluminum casing ensures excellent heat dissipation, and the product comes with a 2-year warranty to guarantee stable, long-term operation in various industrial environments.
