XPWR104HR 12
RTD Embedded Technologies, Inc
Connector descriptions:
Over voltage protected with transient absorber with a working voltage of 36V DC.
Note:
The module input power may be up to 100 W (12.5A), this will require a
cable wire diameter of 2 to 3 sq. mm. Make sure this input wire is kept as
short as possible to reduce voltage drops and input inductance.

X1:
Remote ON/OFF, close this jumper to disable the XPWR104HR
The output voltages are also indicated on the silk-screen on the solder side of the
module under the terminal blocks. Check these before making any external power
connections. The input of the XPWR104HR is protected against reverse voltages, but
will not withstand long term over voltage. The transient absorbers will clip all fast
disturbance and noise on the input, but may overheat if a continuous over voltage is
present. The transorb is intended to handle transients of 1 millisecond or shorter.
