B2B Operation

  mobile operation from dynamo and starter battery (Battery to Battery):
  it refers to charging the main battery through dynamo and starter battery, .If it is not used in the Vehicle , you can also use one battery (12V) to charge another

1. . The efficient charging converter (booster) allows full charging of the board battery during driving.
2. . It increases/reduces the voltage to the level, which is required for precise charging of the board battery with the optimum characteristic line of charging.
3. . The simultaneously supplied 12 V consumers are protected against overvoltage and voltage fluctuations.

Further Characteristics of the Unit
 

• The output voltage is stabilized, free of peaks, smoothed and filtered.
• Galvanic isolation between input and output:

• No overvoltage at the output and thus protection of the consumer if the ground line is lost.
• Clean, undisturbed mass ratios, even with long supply lines.
• Stable operating voltage on site in mobile operation, e.g. Containers, trailers, roll containers etc.
• Filtering and suppression of disturbances on the input to the output side.

• Fully automatic continuous operation: The DC-DC converter can constantly work with the battery
• Surveillance-free operation: multiple protection against overload, overheating, over voltage, short circuit, Misconduct and deep discharge of the battery through electronic regulation to complete
• Switch off by built-in safety switch.

 

Security guidelines

Intended use:
The DC-DC converter was built on the basis of the valid safety guidelines. The use may only be:

1. On lead-acid, lead-gel or lead AGM or LiFePO4 batteries of the specified nominal voltage.
2. With the specified cable cross-sections for inputs and outputs.
3. With fuses of the specified strength near the battery to protect the wiring between the batteries and DC-DC converter connections.

5. In a well-ventilated room, protected against rain, moisture, dust and aggressive battery gases as well as in a non-condensing environment.
The device must never be used in places where there is a risk of gas or dust explosion consists!

Installation of the Unit

 

1. . Install the charger near the board supply battery I (for short charging cables) at a clean, even and hard mounting surface,which is protected from moisture, humidity and aggressive battery gases. The unit can be installed in any position.
2. . To be installed in a moisture-proof, water-proof place, corrosion-proof place
3. . When the charging controller is working, the fan will bring out heat, so when installing, ensure that there is at least 10cm of space behind the charger controller
4. . Choose the appropriate cable specifications, length and fuse specifications, reverse connection of the battery will cause serious damage to the equipment
