Robust 14VDC and 24VDC (13.5VDC to 34VDC) to 12V DC/DC converter
These are regulated switching power converters (switchmode), designed to allow the use of 12 volt equipment 24V vehicles. These 12V output converters have been designed to be very rugged electrically and can be operated continuously at 75°C (65°C for the 2A version).
These are also known as 12 volt voltage reducers, and voltage regulators.
Custom output voltages are available from 3.3VDC to the input voltage minus 1.5 volts (10.5VDC for a 12 volt input, 22.5 for a 24 volt input)
Note 1: Extended operation at voltages less than 13.5 VDC is not recommended although the unit will work at voltages lower than this with reduced load regulation.
Note 2: If an overload is sensed, the unit will automatically limit the output current and reduce the output voltage. If the output voltage is excessively reduced to limit current, the unit will go into a hiccup mode and wait until the overload is removed to restore power. This dual-mode overload protection system allows the unit to be protected from continuous short circuit connection and other overload conditions.
Note 3: Extended operation at temperatures above 75°C can damage the unit and will void the warranty.
Note 4: If the in-line 4A fast-acting fuse is not connected as shown in Figure 2, a reverse polarity connection can damage the unit and will void the warranty.
