Voltage changer PN24/12.4 was designed for reduces 24V vehicle voltage. It makes possible to use actuators, alarms and mobile electronics (satellite navigators, radios, PDAs, windshield cleaners, signal flashers, cigar lighters and etc.) with 12V operating voltage.
The converter’s scheme makes as pulsed step-down voltage stabilizer without smoothing output filter. It has common GND pin for input and output voltages connected to metal housing.
PN24/12.4 restricts inrush current of power loads and increase theirs operating life.
The converter has built-in protections from load short circuit, current overload, pulsed overvoltage and temperature protection. Protection from reverse polarity input voltage guaranties by external fuse.
PN24/12.4 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).
