These are regulated
switching power converters (switchmode), designed to allow the use of 5 volt
equipment in 12V or 24V vehicles. These 5V output regulators have been designed
to be very rugged electrically and can be operated continuously at 75°C
(65°C for the 5A version).
These are also known as 5 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)

Isolation |
Common ground, the negative input is tied
to the negative output. The frame is isolated. |
**Note: the efficiency drops when the input voltage is
above 28 volts, derating either the maximum ambient temperature or output
current is appropriate when operating at the higher voltages
|
Protection |
|
Overload protection |
If there is a short circuit connection
or other overload connection is sensed, the unit will automatically limit the
output current and, depending on severity, will go into a hiccup mode. See Note
2. |
|
Over temperature protection |
If an extreme over temperature condition
occurs the unit will shut down until the temperature is reduced. See Note
3. |
|
Reverse polarity protection |
If an in-line 4A fast
acting fuse (5A for the 5A model) is connected as shown in Figure 2, then the
unit will be protected from reverse polarity connection. If the fuse is
used and there is a reverse polarity connection, the fuse will blow and protect
the unit from damage. See Note 4. |

There are two screw terminals
on the input, and two screw terminals on the output. These are on opposite
sides of the converter. |
|
Note 1: Extended operation at voltages less than 8.0
VDC is not recommended although the unit will work at voltages lower than this
with reduced load regulation. With voltages lower than 7.0 VDC, output voltage
will drop out until the voltage is increased.
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.
