Autoro AB20D DC Dual Power Automatic Transfer Switch ATS 60V/20A/Display | DC5V-60V IN, 20A OUT, Seamless Auto Switch ATS for RV DC Fridge/UPS Power/($35.99Value)

Description

AUTO TRANSFER ZERO-DELAY SEAMLESS POWER: Experience true uninterrupted power with 0-second switching time. The AB20 instantly detects and automatically transfers to the stronger power source (LiFePO4 and LiPO battery banks, also lead-acid, AGM, gel), ups backup power, off-grid power, eliminating downtime for critical systems like UPS, data centers, and security alarms. AB20 is automatical transfer switch, not support set primary and backup power. To set Primary and Backup Power, please go for Autoro AB18 DC Dual Power Automatic Transfer Switch ATS 60V 18A. DUAL‑BATTERY EXPANSION – EXTEND RUNTIME OR INCREASE CURRENT – Connect two LiPo/Li‑ion/LiFePO₄ batteries within DC 5-60V (2 batteries must be within 20V difference). Higher voltage powers the load first; when equal, both discharge simultaneously for longer runtime or doubled output. Perfect for FPV drones (30+ min flights), long‑range ebikes, electric skateboards/e scooters, RC rock crawlers, robotics, and portable surveillance. ADVANCED SAFETY & ANTI-BACKFLOW: Built-in anti-backflow diodes ensure electrical isolation and prevent reverse current between batteries, protecting your power sources. Features an overload-safe control module for reliable performance in emergency and high-stress scenarios DIY-FRIENDLY & INDUSTRIAL READY: Simplifies complex wiring with user-friendly screw terminals. Its compact, mini size is suitable for DIY projects, while the included both din rail mounting and screw mounting support makes it suitable for professional industrial automation and control cabinets IMPORTANT NOTICE BEFORE OPERATION: Before connecting any load to the Autoro AB20 DC automatic dual power transfer switch, please follow the steps below: (1). Connect one input power source and measure the output voltage to verify it is normal; (2). Connect the second input power source and measure the output voltage again to confirm it is normal; (3). Only after confirming that the output voltage is correct, then you can connect your load to the output terminal SMART MONITORING OPTION: Select models feature a digital display (AB20C & AB20D with led display) to provide real-time output voltage, active input source, and power status via LED indicators for smart power management and ensuring your off-grid system is always running optimally WIDE APPLICATION & DEPENDABLE BACKUP POWER: The go-to automatic transfer switch for security cameras, routers, PoE injectors, network switches, electric locks, access control panels, starlink Mini and off-grid communication gear. Ensure 24/7 security and network connectivity even during outages CABLE SPEC & MANUFACTURER SUPPORT: Required cable spec for Autoro AB20A/B/C/D series which is suitable for the supplied metal wiring screws: 14AWG, the diameter of cable for each metal screw terminal should be <2.5mm. Please contact Zhuhai Baoge Technology Co., Ltd. to get direct manufacturer support in case any technical guide required, we will reply you within 24 hours. WIDE VOLTAGE DC5-60V & HIGH-CURRENT 20A: Designed for versatility, this ATS supports a broad DC input: AB20D: DC 5-60V, making it suitable for both 12V and 24V, 48V systems. Handles high-demand loads up to 20A per channel, suitable for inverters, car fridge, solar panel, marine applications, and large off-grid setups.

AB20 Series Dual Power Automatic Transfer Switch (ATS) - Seamless Auto Power Switching

The Autoro AB20 Series Dual Power Automatic Transfer Switch (ATS) is an advanced family of automatic transfer switches engineered for uninterrupted power supply in critical applications. With zero-delay switching, these DC 5V-60V units instantly detect and select the higher-voltage input between two DC power sources—such as ups power, batteries —ensuring continuous operation for off-grid setups, emergency systems, and smart appliances. Their robust control module integrates reverse current protection and dual-source output to handle high-demand loads. Compact and built for durability, they simplify installation with screw terminals, making them perfect for DIY projects and professional use.

Key Features & Core Technology
Zero-Delay Automatic Switching: Instant power transition between dual inputs (e.g., grid/battery, ups backup power/adapter) with no interruption. This auto transfer prioritizes the higher-voltage source and enables simultaneous dual-battery discharge.
Wide Voltage & High Power: Supports 5V–30V/60V DC input and up to 20A per channel. Compatible with 12V / 24V / 48V systems
