Product Information

LB-4811 battery load bank is specially designed for discharge experiment, battery capacity test, battery maintenance, engineering examination and other tests for DC power with load. It is typically applied to 48V and 110V battery system in telecom and power with discharge current adjustable from 0 to 100A.

With its optional Data Acquisition Case (DAC), you will have a real-time monitoring for the whole process of discharge with wireless communication in PC.

Typical application:
Telecom and Power utility 

Why PITE load units?
It is significant to check battery capacity in a regular basis. And the only reliable way to measure the battery capacity is to carry out a discharge test which is a must-to-do job to energize standby batteries and extend their life span.
PITE 3980 series DC load banks feature unique design and excellent performance that will facilitate your work for battery maintenance. It covers different types of batteries (1.2V, 2V, 6V and 12V). With different customer-tailored models, it covers a wide discharge range from 12V to 480V for users from different industries. With optional DAC, discharge values of each cell could be monitored on the LCD display and computer simultaneously by using the PITE PC software.

• Small weight, portable unit with carrying case, convenient for onsite test
• Optional wireless DAC enables its PC monitoring both for discharging and charging
• It sets 4 conditions for auto shut-down of discharge, secured and time-saving
• Continued discharge available when previous discharge is stop abnormally
• Parallel connection of two units for mass discharge
• Real-time display of voltage for each cell with DAC
• Accurate data results and vivid waveforms
• Auto sorting for lag-out batteries during discharging
• AC & DC power supply modes for different needs
• Integrated functions for displaying, controlling and discharging
• Safe circuits avoids damage to battery when testing
• Direct USB drive for convenient data transfer to PC
• Powerful management software for data analyzing and report printing
• Dynamic discharge and static discharge data auto-saving
• Thermal cut-off and automatic overload protection

PITE DataView
All standard load units of PITE 3980 come with analyzing software. With the PITE
DataView software, you have a real-time data monitoring, analyze the testing data and easily print out the complete report.

Optional Data Acquisition Case (DAC)
DAC is optional for wireless communication with PITE 3980 main unit and PC. The new insulation-protected DAC is rugged and capable to measure all type of batteries (1.2V, 2V, 6V and 12V).

Its Connection:
One DAC could be connected with 12 cells of 1.2V, 2V or 4 cells of 12V (or 6V). With DAC, PITE 3980 and PITE DataView software will be able to monitor and record voltage of each cell together with other parameter like String voltage, current, discharge capacity and so on.

In LB-4811 standard unit for testing 2V, 6V and 12V batteries, it needs 5 DACs for cell monitoring.For 12V batteries only,3 DACs are needed.
