The CTS-120 series consists of DC-DC converters, with a galvanic isolation between input and output. The converters operate at a fixed switching frequency and use push-pull converter topology.
There are two options to choose:
1 - With remote sensing
2 - With low output voltage alarm
For maximum regulation, the remote sensing terminals can be connected to the load. This will allow a power cable voltage drop of up to 0.3 V on each cable to be offset.
The device is protected against overload and short-circuits by means of a current limiting circuit. The device is also protected against reverse polarity input voltage, and the input fuse blows if an improper connection is made.
When a converter input undervoltage condition occurs, the converter is disabled, thus preventing the battery from becoming totally discharged.
