GEYA Mini ATS Dual Power Transfer Switch 2-Pole 63A AC110V — Automatic/Manual, Over/Under Voltage Protection

GEYA Mini ATS is a compact two-pole automatic/manual transfer switch that rapidly moves load between two power sources and protects against over-voltage and under-voltage events.

This DIN-rail mounted transfer switch is designed for reliable source switching in small commercial and residential installations that use a mains, generator or photovoltaic array as primary and backup supplies. It combines automatic sensing and manual override, visible status indicators, and configurable protection thresholds for both 110V and 220V systems to reduce downtime and protect connected equipment.

How does the GEYA Mini ATS detect and protect against voltage faults?

The unit continuously monitors both incoming supplies and compares voltages to preset over-voltage and under-voltage thresholds. When a monitored source falls outside safe limits, the ATS will switch to the alternate supply to avoid supplying damaged or unstable power to the load.

• 110V thresholds: undervoltage 85V (recovery 95V), overvoltage 145V (recovery 130V) ±5V.
• 220V thresholds: undervoltage 175V (recovery 195V), overvoltage 260V (recovery 240V) ±5V.
• Automatic return: switches back to normal supply once voltages recover within the safe window.

Can I switch between automatic and manual modes, and how are statuses shown?

Yes — the GEYA Mini ATS supports both automatic operation and manual selection via a red mechanical handle. The device includes clear indicator lights showing which supply is active and whether each source is healthy, simplifying on-site troubleshooting and operation.

• Automatic mode: indicators show active/normal power supply with color-coded lights for quick status checks.
• Manual mode: user moves the red handle to choose supply A or B and the corresponding indicator lights confirm selection.
• Both supplies can be tested while installed to verify readiness before relying on them for failover.

How fast and reliable is the transfer, and will it keep critical equipment running?

The ATS is built to ensure rapid and dependable switching between two sources, minimizing interruption to connected loads. Although it is designed to reduce the effects of power loss and maintain continuity for sensitive systems, it is not a substitute for an uninterrupted power supply (UPS) where zero-transfer-time is required.

• Automatic switching minimizes downtime when the primary supply fails or goes out of range.
• Ideal for systems that tolerate short breaks or where generator start-up is adequate for continuity.
• Not intended to guarantee absolute zero interruption—pair with UPS for truly uninterrupted power.

What installation and system scenarios suit this DIN-rail ATS?

The compact form factor and DIN-rail mounting make the GEYA Mini ATS suitable for control cabinets, distribution boards, and small electrical enclosures. It’s intended for systems where two independent sources — such as utility mains and generator or PV feed — need automated or manual switching with basic voltage protection.

• Common applications: small data racks, cold storage, medical device circuits, telecom or alarm equipment.
• Works with mains, generator, and photovoltaic sources when set up per local wiring rules.
• Requires appropriate circuit protection and wiring by a qualified electrician during installation.

Who is this for? Installers, facility managers and homeowners who need a small, DIN-rail transfer switch that monitors two power sources and switches automatically or manually to protect equipment from prolonged voltage faults. Choose this GEYA Mini ATS when you require compact, visible status feedback and basic over-/under-voltage protection for 110V or 220V systems, but consider adding a UPS for applications where even millisecond continuity is critical.
