DC-DC CONVERTERS AND BATTERY CHARGERS

TDC / TDCi — DC-DC converter 12/24/48 V, 8–30 A

The TDC and TDCi converters power 12 or 24 V loads from a battery of a different voltage and deliver 8–30 A at the output. The input ranges of 9–18, 20–35 and 30–60 V DC cover the 12, 24 and 48 V onboard systems of trucks, boats and off-grid solar systems.

Description

The output voltage of 12.5–13.6 V or 24.5–25 V is regulated, so loads work the same with a discharged and a fully charged battery. A typical example is a radio, a car stereo or a car fridge rated 12 V in a truck with a 24 V onboard system. The TDC series has no galvanic isolation, and its input and output share a common negative, as on vehicles with the negative on the chassis. In the TDCi the input and output are separated by 500 V insulation, which is needed on boats with a hull-isolated system and where sensitive radio equipment must be separated from the noise of power circuits. The TDCi-CH version also works as a charger and keeps a separate battery charged.

How to choose

First choose the input range for the source, then the 12 or 24 V output and a current within 8–30 A with a margin over the sum of the loads. The isolated TDCi is needed when the battery negative is not connected to the chassis. If a battery must be charged at the output, take the TDCi-CH, and for charging a large service battery from the starter battery the Omnicharge DC with power up to 900 W and a current of 50 A at 12 V is a better fit.

FAQ

How can 12 V equipment be powered from a 24 V system?

Through a TDC or TDCi converter with a 20–35 V input and a 12.5–13.6 V output. Choose the current within 8–30 A for the total load, with a margin.

How does the TDCi differ from the TDC?

The TDCi has galvanic isolation between input and output with 500 V insulation, the TDC does not. Isolation is needed on boats with an isolated system and for sensitive radio equipment.

Can a battery be charged from a TDCi converter?

The TDCi-CH version with a charging function is intended for this. The standard TDC and TDCi hold a stable voltage of 12.5–13.6 V or 24.5–25 V without a charging algorithm.

Is the TDC suitable for a 48 V battery?

Yes, the 30–60 V DC input range covers operation of a 48 V bank from discharge to full charge. The output gives 12 or 24 V for standard loads.
