For Inmarsat, the standby (STBY) power supply is linear, causing the power dissipation to rise with input voltage.

The MAIN power supply is a switching mode supply, which means that power dissipation is constant as voltage

increases.

Note that these are average values. Maximum values may be as much as 15% more Note: All currents above are

individual contributions and at 25°C ambient. Total current is the sum of each. Items with burst or slot in the notes are the

peak values.

The power consumed by a GPS device remains constant. It will save power to turn off the GPS during the power

down sequence. It takes about a minute after it powers up to get a GPS fix.

There are no software controllable lines gating power to these devices. The MTS has full flow control for RS-232.

You must ensure that whatever it is connected to is not drawing power from it.

Use of ORBCOMM and Iridium satellite network is not available when modem’s voltage drops below 10.5 VDC.

Relay current is 1A MAX at 25C, .5A MAX at 85C. Power usage depends on customer application.

DC Input power to QUAKE QPRO modems is +6.0V to +32.0VDC. Supplied input voltages outside this range will

result in damage to the modem and void the warranty.
