Smart Over and Under Voltage Switch | Energy Meter | Tuya Smart Life
A Smart Over and Under Voltage Switch is a multi-functional, DIN-rail-mounted electrical safety and monitoring device. It combines the features of a digital energy meter, a smart home IoT device, and an automatic voltage/current protection relay into a single compact unit.
Product features
- Electrical protection: the device constantly monitors the incoming electrical supply and automatically cuts off power (trips) if parameters cross safe thresholds.
- Energy monitoring: equipped with high-precision internal sensors, the device acts as a standard electricity meter, measuring:
- Voltage
- Current
- Active power
- Total energy consumed
- Energy metering: allows you to set energy consumption limits (e.g., limiting a rental unit to a certain amount of active power) and automatically shut off when the limit is reached.
- Voice control: fully compatible with Amazon Alexa and Google Assistant for hands-free operation.
Specifications
- Input voltage: 230VAC @50/60Hz
- Current capacity: 1-63A
- Over voltage: 120-300V
- Under voltage: 80-210V
- Leakage current: 10-99 mA
- Trip delay: 0.5 seconds
- Wireless protocol: WiFi (2.4GHz)
- Mounting type: Standard 35mm DIN Rail
- Operating temperature: -30°C~+70°C
Please use a qualified electrician to install the circuit breaker.
If you have a Samite distribution board, you will need to get an adaptor [click here].
Why get the Smart Over and Under Voltage Switch?
In regions with unstable power grids, frequent load shedding, or unreliable voltage fluctuations, traditional circuit breakers aren’t enough because they only protect against massive overcurrents (short circuits). A smart voltage protector bridges the gap by actively saving appliances from the silent damage caused by subtle high/low voltage spikes, all while giving you deep insight into your energy footprint.
Typical applications (not limited to)
- Geysers
- Water pumps
- Hybrid solar systems
- Rental properties
