ATTE POWER APS-90

Technical Specifications: AC input range 190-260 VAC, 50 Hz; rated output power 90 W; typical output voltage 48 V DC ±3%; output current 2 A; efficiency up to 93% at full load; operating temperature ranges from -10℃ to +40℃.

Functional Features: Built-in input fuse; multi-level protection including over-voltage, over-load and short-circuit protection; AC input surge protection; DC output transient protection; LED power status indicator; mounting hole layout for embedded cabinet assembly; isolation between AC input and DC output.

Application Scenarios: IP-camera monitoring systems, industrial embedded equipment, cabinet internal auxiliary power supply, security monitoring equipment, small-scale industrial automation auxiliary power supply.

Performance Parameters: Short-circuit protection requires power-cycle reset; low output ripple; high efficiency reduces internal heating.

Material Composition: FR-4 PCB board; high-frequency power transformer; electrolytic capacitors; varistor surge-suppression components; metal mounting holes, with open-frame structure and no outer enclosure.

Structural Features: Open-frame bare-board design; 10.8-mm grid mounting hole positions; screw terminal blocks for AC input and DC output; indicator LED on PCB surface; supports horizontal or vertical installation inside the cabinet.

Working Principle: AC mains input passes through the fuse and surge-suppression circuit; the high-frequency switching circuit completes voltage transformation; rectification and filtering generate stable DC output; multiple monitoring circuits detect over-voltage, over-current and short-circuit conditions and trigger protection actions.

Installation Requirements: Install inside a closed equipment cabinet; maintain sufficient ventilation space for heat dissipation; strictly follow terminal definitions for AC and DC wiring; fasten mounting screws through reserved hole positions.

Usage Precautions: The open-frame board must avoid direct contact with metal conductors; prohibit operation beyond the temperature range; short-circuit faults will trigger latch-off protection and require power-on reset; do not cover components to prevent heat accumulation.
