-In the field of new energy, it is used for on/off control, voltage monitoring, and protection of DC circuits in photovoltaic inverters, wind power converters, and energy storage systems to ensure the stable grid connection and safe operation of new energy generation systems.

Installation and usage precautions

Before installation, it is necessary to confirm that the coil voltage, contact capacity, and other parameters of the relay match the actual working conditions to avoid equipment damage or control failure caused by parameter mismatch.

2. During the installation process, ensure that the wiring is secure and avoid false connections that may cause contact heating or arc erosion; At the same time, pay attention to distinguishing between coil terminals and contact terminals to prevent incorrect wiring.

3. Relays should be installed in an environment with good ventilation, no severe vibration, no corrosive gases, and strong magnetic fields, away from high temperature heat sources, to ensure that their operating temperature is within the rated range.

4. During use, regular inspections should be conducted on the relay to check for any erosion or oxidation of the contacts, as well as any abnormal conditions such as overheating or odor in the coil. Any problems found should be promptly addressed.

When replacing relays, products of the same model or compatible parameters should be selected to avoid arbitrary replacement that may cause system control logic disorder or equipment failure.
