Power Supply - MTX M2M MTX-DIN Series User Manual

MTX-DIN Family

4.2.2 Power supply

The MTX-DIN modems are powered through pins 1 and 2. The power supply must be in the range of
9 to 30VDC or 12 to 24VAC to ensure the correct operation of the modem.
At pin number 4 there will be available a voltage output of 9V, which can power any load up to
500mA.
The power supply has to be a single voltage source capable of providing a current peak during an
active transmission. The uplink burst causes strong ripples (drop) on the power lines.
The modem module is switched on at the same time the modem is powered. It also has an Automatic
Restart after Shutdown feature that allows an application to always be switched on and to restart
itself.
The LED called POWER (see the label) will illuminate when power is present.
