Abstract

PURPOSE: To protect cells by reducing the power to load circuit, when the cell voltage is lowered, which utilizes natural energy.
CONSTITUTION: If the voltage of the unit 1 or secondary cells charged in floating with the battery 1 by natural energy is less than a set value, all or a part of the power supply supplied to the spare unit or existing unit for the auxiliary circuit of transmission power amplifier of the load radios 4 is interrupted, allowing them to be in practical communication and to protect secondary cells.
