NKA 160505 – 5V / 0.5A SMPS Adapter
Ultra-Compact 5V Solution for Low-Power Electronic Devices
The NKA 160505 is a single-output, 5V / 0.5A AC-DC switching adapter designed with advanced high-frequency technology. Operating across an impressively wide input range of 100–300 V AC, this compact and efficient adapter ensures stable DC power for small telecom equipment, IoT devices, and other low-power applications. Its natural convection cooling and wall-mountable design allow for easy installation in space-constrained environments.

Product Highlights & Benefits
Compact Design: Easily fits into tight installations while maintaining airflow for natural convection cooling.
Wider Input Voltage: Operates effectively from 100–300 V AC for universal suitability.
SMPS Based: High-frequency switching ensures better efficiency and lower heat output.
Robust Protections: Overload, short-circuit, and over-temperature features keep devices safe.
User-Friendly Mounting: Simple wall-mount form factor reduces clutter.
High-frequency switching design reduces size and improves power density.
Stable 5V DC output for sensitive electronic applications.
Overload: Output folds back, automatically resumes upon load correction.
Short Circuit: Hiccup mode to prevent damage; normal operation returns once short is cleared.
Thermal Shutdown: Proactively stops operation if internal temperature rises too high.
Operating Temp: 0–50 °C, Storage Temp: 0–70 °C
Humidity: 5–95% RH (non-condensing)
Enclosure: Rugged plastic housing with flame-retardant rating (UL94 V-0 if applicable).
Safety, EMI & EMC: Designed to meet IEC 60950 and CISPR22 / IEC61000 for EMC.
Insulation: 1.5 kVac isolation between input & output.
