Programmable DC Discharge Testing

PITE3980 DC Load Bank

Verify battery capacity with programmable constant-current discharge testing, live monitoring and Excel-ready reports.

PITE3980 is built for capacity, performance, acceptance and compliance discharge tests. It combines stable load control, automatic shutdown logic, wireless/USB data transfer and optional per-cell voltage monitoring with DAC accessories.

Current range12-600 A
Parallel loadUp to 1200 A
Voltage range10-576 V
Discharge modeConstant current
DAC cells1.2V, 2V, 6V, 12V
ReportsExcel export
Capacity Test Platform

Run controlled discharge tests with protection built in.

Discharge testing is the practical way to verify real battery capacity. PITE3980 maintains the preset current until the test reaches a configured stop condition, giving maintenance teams repeatable results for battery systems, UPS rooms, rectifiers and DC power plants.

  • Programmable constant-current discharge for capacity and performance tests.
  • Auto-shutdown by time, total string voltage, capacity or individual cell voltage.
  • Built-in circuit breakers support emergency shutdown and overload protection.
  • Parallel operation with another LB-Series unit increases available current capacity.

Test Workflow

Set the discharge target, monitor live data, export the record.

Discuss your test current
01

Select the model

Choose voltage and current capability based on the battery string, discharge rate and site limits.

02

Connect load and DAC

Connect the load bank to the string, then add optional DAC leads when per-cell voltage is needed.

03

Set stop conditions

Configure current, duration, capacity, string voltage and individual cell voltage shutdown limits.

04

Review and report

Monitor data live, identify weakest cells and export a structured Excel report for records.

DAC Cell Monitoring

Measure every cell during the discharge, not only the total string.

The optional Data Acquisition Case connects to individual cells and communicates back to the load bank wirelessly. This helps teams see which cells collapse first, replace only the cells that need replacement and reduce manual measurement work during long discharge tests.

  • Each DAC can monitor up to 12 cells depending on cell voltage and wiring scheme.
  • Compatible with common VRLA, VLA, NiCad and other battery systems.
  • Standard and customized DAC packages support different cell voltages and configurations.

For 2V cells

One DAC can monitor up to twelve 2V cells; custom packages are available for uncommon cell arrangements.

DataView Software

Live monitoring, data review and report export.

DataView can monitor discharge tests in real time or import records from the USB drive. Teams can review group voltage/current, each cell curve, detailed tables and weakest-cell trends before exporting reports to Microsoft Excel.

  • Live group voltage and current curves
  • Cell voltage graphs and detailed tables
  • Weakest-cell comparison during discharge
  • Company, site and battery information in reports

FAQ

Common load bank questions.

These answers summarize the current product guidance for battery maintenance and capacity testing teams.

How do I choose the right load bank?

Choose the model by the battery string voltage and the discharge current you need. For example, select a 48V model for a 48V battery pack and choose the current rating from the target discharge rate.

Does PITE3980 include software?

Yes. PITE3980 includes DataView software for live monitoring, test-data review and exporting discharge reports to Microsoft Excel.

How is cell voltage monitoring accomplished?

Optional DAC accessories connect to the cells with a wiring harness and communicate wirelessly back to the load bank, allowing each cell or block voltage to be recorded during the discharge.

Can PITE3980 work with existing load banks?

Yes. Assistant discharge mode helps add current capacity and individual cell monitoring when working with existing non-LB load bank equipment.

What power supply does the load bank need?

The exact power consumption depends on model and discharge current. The product page guidance notes that external AC power is 110/220 VAC, 50/60 Hz, and the draw is normally below 9 A at maximum current.
