This is an adjustable over/under voltage and over-current protection device, also known as a voltage protector or smart circuit breaker.
Specifications
- Rated Current: Common ratings are 40A, 63A, or 80A.
- Input/Operating Voltage: Typically operates on AC power, with ranges often around AC140-300V or AC 80V-400V, depending on the specific model (e.g., 110V or 220V variants exist).
- Protection Functions:
- Over-Voltage (OV) Protection: Automatically disconnects power if the voltage exceeds a set limit (e.g., default 270V, adjustable from 230-300V).
- Under-Voltage (UV) Protection: Disconnects power if the voltage drops below a set limit.
- Over-Current (OC) Protection: Disconnects power if the current draw exceeds the set amperage limit (e.g., adjustable 1-63A or 1-60A).
- Display: Features an LCD screen that displays real-time voltage and current data.
- Adjustability: Settings for over/under voltage values, over-current limits, and power-on delay times (e.g., 1-500 seconds) are adjustable via the front panel buttons.
- Installation: Designed for din-rail mounting, suitable for integration into an electrical panel.
