Description

The TS400C is a DC/DC converter for charging an auxiliary battery in vehicles with smart alternators, or for protecting alternators in lithium LiFePO4 systems.
In Euro 5 and 6 engines, the ECO alternators used (controlled by the vehicle electronics) generally do not deliver a continuous, correct charging voltage even when the engine is running. Therefore, a special DC/DC converter is necessary to properly charge the auxiliary battery. In lithium LiFePO4 systems, a special DC/DC converter is required to prevent alternators from burning out.

About the Full range automotive DC/DC TS 400-25(2)

To save the vehicle’s starter battery, the TS 400 will only supply power once the engine is running. This is possible thanks to the built-in engine-run detection. Instead of this detection, the TS 400 can also be switched on via a programmable input.

The TS 400 is fully programmable via a very simple and clear PC application.
The output current (maximum 25A) has an adjustable automatic limit.
The automatic limit becomes active as soon as the temperature approaches a set maximum.
The output voltage is adjustable for all automotive situations and is independent of the input voltage due to the automatic buck/boost control. This control also ensures that the current will never exceed the set value, even if the input voltage is higher than the output voltage.

Frequently Asked Questions
Q: I have a relay in my Euro 5/6 vehicle but I’m not experiencing any problems charging a second battery.
A: If your driving style doesn’t trigger the smart alternator and you use little energy from your battery, you might not notice much for the time being.

Q: Do I only need to replace my relay if I want to install a DC/DC converter?
A: Yes, just replace the relay with a DC/DC converter and connect it according to the diagram.

Q: I have a Euro 6 engine and measure voltages (in a 12V vehicle) above 15V; can the DC/DC converter also convert this?
A: Yes, the DC/DC was partly developed to step down this high voltage.

Q: Can I change the settings in the DC/DC converter myself?
A: Yes, this DC/DC converter is programmable as desired with custom software.

Q: When I turn off the car, does the DC/DC converter also turn off?
A: Yes, the DC/DC uses a built-in engine run detector to sense whether the engine is running and will turn off when the engine stops.

Q: With a Euro 6 alternator, the alternator can even freewheel and supply minimal current; how does the DC/DC converter handle this?
A: The DC/DC converter will then discharge the starter battery while driving, causing the state of health sensor to increase the alternator voltage again and start supplying current.

Q: If I program an intelligent relay with a programmable value to a lower voltage, will that work?
A: No, the result is that the second battery is first completely discharged and then can no longer be charged due to the low alternator voltage.

The full range automotive DC/DC converters are suitable for charging an auxiliary battery in vehicles with smart alternators, or for protecting alternators in lithium LiFePO4 systems. Very easy to set up and features engine run detection via a built-in vibration sensor.
