7-6. Constant-Current Charging/Discharging of Battery
7-6-1.
Constant-current charging
It is possible to charge a battery or capacitor automatically with a charging current or a final
voltage preset.
1) Keeping the V/I CHECK switch depressed, set the final charging voltage with the
constant-voltage control and the charging current with the constant-current control.
2) Close switch S1, and constant-current charging starts and continues until the final
voltage is reached.

Note 1 : Be sure to equalize the polarity of the supply power and battery.
Note 2 : Current would flow back into the power source if the supply voltage is lower
than the battery voltage, the OUTPUT switch is off, or power supply is turned
off. In this case reconnect diode D
1
in the forward direction.
7-7. Turning On and Off the Output Using External Contact Signals
1) Set the OUTPUT selector switch on the front panel to OFF.
Short-circuit the DIN connector pins 1 and 4 in the upper left of the rear panel.
