DC/DC Converter PN24/12.8

  • converting 24 V to 12 V
  • 50 A load current
  • two-color operating status indicator
  • smoothing output filter
  • aluminum housing

PN24/12.8 voltage converters supply power to consumers with the rated voltage of 12 V in vehicles with the rated voltage of the on-board electric system of 24 V.

They are designed as a pulse step-down voltage stabilizer without galvanic isolation.

The converters smoothen the output voltage buildup when the power is on and limit the starting currents at high loads.

Our converters feature the in-built protections from overcurrent and load short circuits, reverse supply voltage, power supply peak overvoltage, and overheat with automatic restoration.

They have a two-color operating mode indicator (operation/protection).

Converter operating modes

The input voltage supply is indicated by the warning indicator that lights up green. If the indicator is off, check whether the input voltage is supplied and whether the voltage polarity between «+24 V Input» and «Common» terminals is correct.

If the input voltage is within the allowed range, disconnect the wires from «+12 V Output» terminal of the converter. If the indicator lights up, any overload or short circuit in the load circuit should be detected and eliminated.
