Power supply module, step-up converter CV/CC 1200W /DC-DC charger

Non-isolated step-up DC-DC pulse converter 10–60V / 12–75V with setting of output voltage 12–75V, current limit 0–20A and minimum input voltage 9–50V for battery protection. The excess of the battery protection voltage setting (> 9V, where Uvst> 10V) is given by the uvst / uvster hysteresis. Fixed voltage 12V for possible fan connection. Its function is predestined for connecting the second battery to cars with a smart alternator, where direct connection of a parallel battery is not possible.


Technical parameters :

- input protection fuses-2 × 15A
- no-load current type.15mA
- 12 V output for fan
- undervoltage protection setting: 9–50 V (to charge the external battery, set so that the module is active after starting the vehicle)
- efficiency 95%
- dimensions 130 × 52 × 46 mm


The product is not a stand-alone unit, it requires professional installation.
