DC Load Bank

Model: PITE3980

PITE3980 DC load banks are designed for user ease of use, portability, and versatility in mind. Discharge testing batteries is the only verifiable method the capacity of your batteries and the PITE3980 delivers a programmable, constant current load for your testing needs. Whether you are  load testing for capacity, performance, acceptance, NERC compliance, or other, the PITE3980 provides an economical complete package solution. Increase employee and battery system safety with PER CELL monitoring and standard built in auto-shutdown features. To suit a variety of industries and diverse applications, we offers over 75 standard models to fit your exact needs at the best price

  • Safely monitor live tests remotely with wireless communication to the DC load bank

  • DataView software includes live monitoring, data recording, and report exporting to Microsoft Excel

  • Discharge auto-shutdown for time duration, total string voltage, capacity, and individual cell voltage

  • Parallel with another LB-Series unit for increased discharge current capacity

  • Assistant discharge feature allows for compatibility with existing nonLB load banks

  • Increase current and add individual cell monitoring to your existing equipment with LB-Series

  • Built-in circuit breakers for emergency shutdown and overload protection

  • Optional: Real-time display of voltage for each cell/unit with DAC package for 1.2V, 2V, 6V, 12V cells

  • Optional: Custom DAC packages available for monitoring of uncommon cell voltages and configuration

DAC (Optional accessories)

PITE3980 DC Load Banks come with an optional DAC package allowing the voltage of EACH CELL to be wirelessly monitored and recorded during discharge. The DAC package allows the user to evaluate the health of each cell and replace only the cells that require replacement saving time and money by significantly reducing labor hours and replacement costs

Typical connection of DAC’s to the battery cells include a test lead connected to each cell from the DAC. Each DAC can connect up to 12 cells. DAC’s are expandable to any size battery system and are compatible with VRLA, VLA, NiCad, and other battery types

DAC Wiring

Normally 1 PCS DAC could monitor 4 PCS 6V/12V batteries or 12 PCS 2V batteries, other special customized DAC is also available, upon custom's request, just let us know what kind of battery you need to monitor and how many pcs you need to monitor, we would provide you the best solution immediately

Data View Software

The included DataView software allows the user to monitor the discharge test in real- time or import and view tested data from the load bank with the provided USB drive. View and print a detailed histogram of each cell’s voltage from any point during the discharge test at user defined intervals of 15, 30, or 60 minutes

Recorded data exports directly to Microsoft Excel. Users are able to customize thereport with company name and location as well as input battery information including battery make, cell type, rated capacity, and more. The complete test criteria, weakest cells, string information, and individual cell information are included in the report. Graphs for string, and cells are also available to view in the software

Does the PITE3980 come with software?
Each PITE3980 comes standard with Dataview software. This software allows us to live monitor, view test data, and export reports to Microsoft Excel

How is cell voltage monitoring accomplished?
The PITE3980 utilizes DACs (data acquisition cases) to connect to each cell. The DAC includes a wiring harness that connects to the cells. Each DAC communicates back to the PITE3980 load bank wirelessly

What is the power requirement for the PITE3980?
The exact power consumption of an PITE3980 varies with model and discharge current, however expect the draw to be less than 9A at max current. A 15A circuit breaker is sufficient for power needs
