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).
