General Description

Brand / Model: SINOTIMER MATS100 (4P, three-phase)

Nameplate Current: 63A on all 4 poles

Type: Automatic transfer switch (ATS), designed for photovoltaic (PV) systems powering

Main Features

• Photovoltaic Application: optimized for solar systems, allowing automatic switching between the main grid and inverter PV when the main source fails.
• Fast Switching: transfer occurs in less than ~50 milliseconds, ensuring continuity even during short power outages.
• Installation on DIN Rail: compact design, easy integration into standard panels.
• Automatic and Manual Operation: can manually select the power source or let the switch manage it automatically based on availability.

Main Benefits

• Safety and Continuity: detects voltage drops or outages from the main grid and quickly switches to the inverter solar energy, preventing significant energy loss.
• Flexibility: adjustable for manual or automatic control depending on needs.
• Space Saving: mounting on DIN rail provides a neat and efficient electrical panel.

Technical Specifications

• Nameplate Supply: AC 220-400V, 50/60Hz
• Number of Poles: 4 poles (three-phase + neutral)
• Rated Current: 63A
• Switching Time: 50 ms
• Installation Method: DIN Rail
• Operation: Manual or automatic
• Application Field: PV systems, generators

Note: For single-phase applications, there is also a 2P version, 63A (model MATS1002P63PV).

Practical Opinion

This switch is ideal for three-phase photovoltaic installations with a dedicated inverter, where automatic switching between different networks (main grid and PV source) is desired. The rapid switching time ensures seamless continuity without disruptions, and mounting on a DIN rail makes integration into modular panels straightforward.
