Product Details
iDU is a DC UPS integrating multiple functions into one unit,
including a smart battery charger, battery monitor and the load
management. The built-in professional adaptive charging algorithm
with automatic temperature charging makes it suitable for composing
a power backup system for various outdoor equipments, such as DAS,
RF and FTU etc.
Features:
- Power factor correction.
- Professional temperature compensated battery charging control.
- Working temperature: -40℃-70℃.
- Low power consumption.
- IP55 design.
- System data monitor via RS484 communication.
- Real-time power supply data.
- Real-time alarm data.
- Real-time battery data, including battery voltage and discharging
current.
- Complete protection.
- Over voltage.
- Over current.
- Over temperature.
- Short circuit.
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.
