NKC167515 Charger (Two-Output SMPS)
Simultaneous Load & Battery Charging in One Compact Solution
The Naskon NKC167515 Charger is designed to power a primary load while simultaneously charging an attached battery—ideal for FCTs, CCTV systems, GPON ONTs, and other equipment requiring backup power. Engineered with high-frequency switching and robust thermal management, this tabletop/wall-mountable adapter ensures low ripple/noise, over 80% efficiency, and a wide AC input range of 90–300 V for universal deployment. Built-in visual indicators keep you informed about battery status, from “charging” to “full” and “battery low,” ensuring you stay in control at all times.

Product Highlights & Benefits
Simultaneously Power a Device while Charging a Battery, eliminating the need for separate adapters or chargers.
Visual LED indicators for battery states (charging, full, low) ensure instant status checks.
Operates reliably under fluctuating mains conditions common in residential, commercial, or remote areas.
Over 80% efficiency at typical loads helps minimize heat buildup and reduce operating costs.
High-frequency switching and quality filtering components protect sensitive electronics like CCTV or FCT systems from interference or damage.
Output Overload: Automatic fold-back, resumes once overload is cleared.
Short Circuit: Hiccup mode; normal operation restores after fault removal.
Battery Reverse Polarity: Prevents potential damage if the battery is connected incorrectly.
Over Temperature: Shuts down to protect components, restarts when safe temperatures are reached.
Detailed Features / Technical Details
