2.1 Power Supply Requirements for the SMART7

The SMART7 requires a power supply that provides:
a voltage in the range of +7 to +30 VDC
l
at least 15 W of power (typical use: 3 W to 7 W)
l
See SMART7 Environmental and Electrical Specifications on page 133 for more power supply spe-
cifications.
The SMART7 has an internal power module that:
filters and regulates the supply voltage
l
protects against over-voltage, over-current and high-temperature conditions
l
provides automatic reset circuit protection
l
If the voltage supplied is below the minimum specification, the receiver suspends
operation. If the voltage supplied is above the maximum specification, the receiver
may be permanently damaged, voiding the warranty.
The supply must be capable of providing enough current to operate the SMART7,
including the initial inrush transient. The supply must also be current limited to 5 A
with an external fuse.
The amount of power required depends on the number of constellations and signals
tracked, and the features enabled.
Refer to SMART7 Interface Cable (Optional Accessory) on page 136 for details about the power
cable.

2.2 Mounting and Orienting the SMART7

2.2.1 Mounting
