and Float mode. During charging period, you can change the select switch to read the battery voltage or
charging current from LCD meter at any time.
• Battery condition detect by LED bar-graph. The controller can indicate the battery condition
with three states: GOOD, FAIR, LOW.
• PWM constant-voltage regulation to prevent heating and excessive battery gassing. Pulse
charging to restore full battery capacity.
• Float: After battery is fully competed charged, the battery voltage will reduce to a lower
regulated voltage in which safety maintains the battery at full charge.
