Yueqing Lovadon Electric Co., Ltd.

General

Self-recovering photovoltaic-specific recloser actuator: compatible with LC60N miniature circuit breakers. This device upgrades the  circuit breaker with intelligence without affecting the main body of the breaker. It can perform remote automatic closing and opening  control via MODBUS 485, while also providing overload and short-circuit protection for the line. It also features parameterizable configurable functions that can be determined automatically by the MCU, enabling the functionality of disconnecting during a power outage and  automatically reconnecting upon the arrival of power. It is currently widely used in photovoltaic grid-connected AC distribution boxes, as  well as in situations where personnel are difficult to access, where maintenance personnel cannot arrive promptly, and where there is a  high requirement for uninterrupted power supply.
