Charging Curve

From the picture, you will see the charging curve, and help you understand more about our DC UPS charging. ( status for Soft Start~Bulk~Absorption~Float~Recycle)

• When AC grid is available, iDU offers 3 steps’ smart charging to the battery. At the same time, it offers the power supply to the load.
• When AC grid is not available, battery offers the energy to the loads. iDU alarms via dry contact.
• When battery discharged until the low voltage protection level, iDU cut off the output of battery and alarms via dry contact.
• When the battery in the floating state for a long time, in order to avoid plate passivation, the module will automatically periodically activation process, at the same time also provide remote manual activation interface and local activation key, convenient for the user to control the active state.
