Dual Power Automatic Transfer Switch 100A 2P AC230V for UPS, Solar and Grid, Millisecond Switching

Dual Power Automatic Transfer Switch 100A 2P AC230V for UPS, Solar and Grid, Millisecond Switching Description

Dual Power Automatic Transfer Switch - 2‑pole, AC 230 V, 100 A Millisecond‑speed circuit controller designed for household photovoltaic (PV) systems and uninterruptible power supply (UPS) setups. **Key Benefits** **Instant power continuity** - Switches between primary and secondary sources within a few milliseconds, keeping lights, appliances and communication equipment running without interruption. **‑current capacity** - Handles up to 100 A at 230 V, suitable for most residential load requirements. **Fully automatic operation** - Detects loss of the main supply and transfers load to the backup source without user intervention. **Dual‑input flexibility** - Connects both a solar inverter and a conventional grid or generator line, giving you control over which source supplies power. **Robust construction** - Housed in a metal enclosure with heat‑resistant internal components for long‑term reliability. **Compact footprint** - Fits easily into standard indoor utility cabinets or wall‑mounted panels. **Core Functions** Detects voltage drop on the primary line and initiates transfer to the secondary line. Returns to the primary source automatically when normal voltage is restored. Provides overload protection and short‑circuit isolation for both input circuits. Indicator LEDs show operating status, source selection and fault conditions. **Compatibility** Designed for AC 230 V residential PV inverters. Works with standard UPS units that deliver AC output. Accepts conventional grid supply or generator output as the secondary source. **Physical Characteristics** Dimensions: approximately 250 mm 150 mm 80 mm (L W H). Enclosure material: cold‑rolled steel with powder‑coat finish. Mounting options: DIN‑rail, wall or panel mounting using supplied brackets. Operating temperature range: -10 C to 50 C. **Performance Highlights** Transfer time: less than 10 ms, ensuring no perceptible outage. Continuous current rating: 100 A at 230 V AC. Rated for up to 10 kW of connected load. Low power consumption in idle mode (< 5 W). **Typical Applications** 1. **Residential solar backup** - Connect a rooftop PV inverter as the primary source and a grid line as the backup. When the grid fails, the switch instantly transfers the home's load to the solar system, maintaining lighting and essential devices. 2. **Home office with UPS** - Pair the transfer switch with a UPS that feeds a secondary source. During a power cut, critical equipment such as computers, routers and security systems stay online while the UPS supplies clean power. 3. **Generator‑assisted power supply** - Use the switch to alternate between grid power and a standby generator. When the grid voltage drops, the switch automatically engages the generator, keeping heating, refrigeration and medical equipment operating without manual switching. **Why Choose This Transfer Switch** Provides reliable, automatic source management for solar‑based homes. Eliminates manual switching, reducing the risk of human error. Supports ‑current household circuits, eliminating the need for multiple smaller units. Simple installation with standard mounting options and clear status indicators. The Dual Power Automatic Transfer Switch delivers fast, dependable protection against power interruptions, making it an essential component for any residential PV or UPS installation.
