lead acid charger, 10a - Cell-Con
LEAD ACID CHARGER, 10A
Switch mode lead acid
chargers are designed to
effectively charge sealed
lead acid batteries
while protecting the
batteries from overcharging. All charger
ratings are based on
a nominal input of
110-120 VAC/ 50-60Hz.
The output current
ranges from 2.5A to 10A.
Features:
• 3 step charge control with timer
• Switch mode charger
• Available in 12V, 24V, 36V and 48V
versions
• LED status indicator
• Protected against reverse polarity
and short circuit
• Medical approved (EN60601)
• Custom specifications on request
• Waterproof version available

Functionality:
Once the charger is attached to a sealed lead acid battery and plugged in, the charging process will begin.
The charger will subject the lead acid battery to three steps of charging.
In the first step, the charger will enter into ‘boost’ mode. During this step, the charger is in constant current
mode with the current rate remaining at its maximum value (note- the battery voltage is lower than
the switching level of the timer).
In step two, the battery will be nominally 80-95% charged, and the charger will switch into time controlled/
constant voltage mode (current is no longer being provided at its maximum rate). The charger will
continue to provide a constant voltage until the time interval is completed.
The third and final step will place the charger in float/standby mode as the battery will be fully charged.
Because the charge voltage is at a standby level, the charger can continue to be connected to the battery.
Should the battery be used, the charger can return to rapid charging (step 1).

LED status indicator:
The lead acid charger has an LED status indicator to inform the user of its status. During step 1, the
LED appears red. In step 2, the LED appears orange. During the third step, the LED appears green.
