Change the settings or update CV-03 converter

It is possible to change the default settings with attached software trough a USB MINI, mini B (<2019) or a USB MICRO (>2019) connector located under the white cover.

Please read the attached PDF procedure to open the box without damaging it, and download the software matching your computer.

If needed, step-by-step instructions are available to update the converter :

• Step-by-step instructions for converter update (with WINDOWS)
• Step-by-step instructions for converter update (with MAC)

It also possible with this software to visualize and record data from CV-03 at 1 Hz rate (in My Documents folder) and to reprogram the firmware if needed.

Current firmware version :

Firmware v3.13

 (caution :  for 48V converters use the specific 48V version)

 Firmware update steps :

• The converter must be powered during this operation
• plug the USB cable to the computer
• if needed please download and install the VCP drivers provided by FTDI ( see attached files below )
• move the .hex file on desktop (otherwise it could lead to failure in case of specials characters in the DOS path of another folder)
• download and launch the application and connect the converter. ( see attached files below )
• NOTE for MacOS : the launch might be denied. You have to authorize the application in Preferences Panel > Security > Open the app
• enter the firmware tab, select the .hex file and launch the update
• wait for the update
• in case of success the version should be displayed in the application at next connection.

Compatibilty :

Windows 64 bits

MacOs X

Adjusting the converter settings

These parameters should be modified ONLY by following the technical specifications of the batteries.

• ABS Voltage : absorption voltage
• FLOAT Voltage : floating voltage
• Reset-To-Abs Voltage : voltage value under which the converter starts a new charge cycle. (this parameter should be modified for Lithium batteries - please refer to other articles)
• ABS Cycle duration : duration of the absorption cycle  (this parameter should be modified for Lithium batteries - please refer to other articles)
• Min Reset-To-Abs duration : minimum duration before 
• Max box internal temperature : maximum operational internal temperature of the converter. Above this value, the production power will decrease to maintain the temperature to an acceptable level - Do Not Modify
• Max output current : Maximum charge current - Do Not Modify
• Charge mode : to force the voltage to 12 or 24V  (parameters to be modified for Lithium batteries - see associated articles)
• LED Brightness : led brightness setting - from 0 to 100%
• LED shutoff voltage : at this voltage value, the converter led shuttoff
• Red Led Voltage : low battery voltage - red light

• Green Led Voltage : high battery voltage - green light
