Function Features: Built-in EMI filter, active power factor correction, overvoltage protection, overload protection, thermal overload protection, remote sense on main output, single wire current sharing, power fail signal, remote inhibit function, adjustable output voltage on multiple channels.

Application Scenarios: Industrial controllers, automation equipment, test and measurement instruments, ITE commercial embedded systems, telecommunication equipment.

Material Composition: Metal open frame chassis, ferrite core transformer, electrolytic capacitor, power semiconductor devices, printed circuit board, magnetic components.

Structural Features: Chassis mount open frame structure, optional metal protective cover, internal ventilation slots for natural heat dissipation, screw terminal connection.

Working Principle: AC input is rectified and power factor corrected, then converted to high frequency AC through switching topology, multi-channel secondary rectification and filtering generate multiple stabilized DC output voltages.

Installation Requirements: Chassis screw fixed installation, ensure adequate ventilation space around the unit; forced air cooling is required to achieve full 175 W power rating; connect input and output wiring according to terminal markings.

Usage Notes: Derate output power when ambient temperature exceeds 50 ℃; avoid condensation environment; verify input voltage range before power on; do not operate without cover in personnel accessible areas to prevent electric shock hazard.
