Instructions of use Product overview

Instructions for use

◆ When no battery is connected, the output voltage of the module is the cut-off voltage of battery charging.
◆ When the battery is charged and discharged, the output voltage follows the battery voltage.
◆ Priority load power supply. When the energy of the CT is insufficient, the CT and the battery jointly supply
power to the load. When the energy of the CT exceeds the load power requirement, the battery is charged at the same time. CT power supply and battery power supply can be switched seamlessly.
◆ When the conductor current is too large and the CT output voltage is too high, the protection circuit of the energy taking module starts, and the thyristor is controlled to switch continuously, and the input voltage islimited to a certain value.
◆ Under the condition of dual input of CT and solar photovoltaic panel, the power supply of CT is preferred. When the power supply of CT is insufficient, the power supply of CT and solar photovoltaic panel is jointly supplied.

Pilot lamp

◆ Green light, normal output
◆ The red light is on, and the electric CT energy is sufficient
◆ Red light, green light, electric CT energy is sufficient,the output is normal
◆ Green off, the output is abnormal
