About the BDL-3927:
  • BDL-3927 is updated Battery Data Logger to meet IEEE measurement standards for battery voltage, string voltage, current and ambient temperature. It is customized from 12V to 700V for different battery systems. And it has easy expansion for all battery systems. With wifi communication, you could easily view complete data and generate test report in the PC software.

Features:
  • Small weight modular design and very easy to install and operate

  • It tests all battery types of 1.2V, 2V, 6V and 12V

  • Simple wifi communication between battery data logger and PC

  • Simultaneously monitor cell voltage, string voltage, current & temperature

  • Data is automatically saved in PC, no need extra data transfer

  • Work with battery charger or load bank to reflect complete battery status

  • One Cell Data Logger is connected with up to 12 cells, save your time and money

  • Could be used as temporary voltage monitoring or as permanent battery monitor

  • Direct powered by battery, no need for extra power supply

  • Good price with complete measurement functions

>>> Cell Data Logger (CDL)
It monitors voltage of each cell in real time. For different battery system, depending on different battery systems, each battery string will require different amount of CDL.
Each CDL is connected with up to 12 cells of 1.2V, 2V, 6V and 12V.

>>> String Data Logger (SDL)
Each battery string will only need ONE SDL.
It monitors string voltage, string current (optional with CT) and ambient temperature. Each SDL will come with a customized current sensor for testing string current.

>>> Router
A router is connected with PC via LAN or Wifi. It is for receiving all measurement data from CDL and SDL.

>>> Optional Current Transducer (CT)
Optional part connected with SDL for monitoring of string current value.

Standard Accessories:

- String DAC

- PC Software
