DC/DC Converter PN24/12.5

  • conversion 24 V DC 12 V DC
  • output current maximum 20A
  • overvoltage, overload and overheat protections
  • two-color LEDs status indicator
  • low level of pulsation of output voltage
  • aluminium housing

A lot of products such as satellite navigators, PDAs, radios, control systems and etc. are available only with 12V operating voltage. The voltage changer PN24/12.5 was designed for uses power 12V products on 24V vehicles.

The converter's scheme was made as pulsed step-down voltage stabilizer with smoothing output filter.

Switching on loads PN24/12.5 provides smooth progressive output voltage and restricts theirs inrush current.

The converter has built-in protections from load short circuit, current overload, pulsed overvoltage and overtemperature.

PN24/12.5 has two-color status indicator. Green light indicator shows normal condition of converter. Red light indicator demonstrates emergency state (overload, short circuit, overheating, low or high input voltage).
