POWER REQUIREMENTS
Voltage
Normal Mode: +3.3 VDC +5%/-3%
OEMV3 Compatibility Mode (power via main header): +4.5 VDC to 36 VDC
For best performance, NovAtel strongly recommends additional supply bypassing
as close as possible to the OEM638 supply pins.
For the 3.3V supply - minimum 22 uF in parallel with 0.1 µF
For the wide-range supply - minimum 44 uF in parallel with 0.1 µF
Allowable Input Voltage Ripple 100 mV p-p maximum
Power Consumption
2.65 W typical, GPS L1/L2/GLONASS L1/L2/BDS B1/B2
2.8 W typical, GPS L1/L2
3.0 W typical, GPS/GLONASS L1/L2
3.1 W typical, GPS L1/L2/L5, GLONASS L1/L2, (without L-Band)
3.1 W typical, GPS L1/L2, GLONASS L1/L2 (with L-Band)
3.3 W typical, all on (without L-Band)
Power consumption values assume Ethernet is disabled. Ethernet draws
approximately 450 mW. If reduced power consumption is required, turn off the
Ethernet port as outlined in
Chapter 6, Ethernet Configuration
on page 86 and the
ETHCONFIG command described in the
OEM6 Family Firmware Reference
(OM-20000129)
The above values can change with the number of satellites in view and the
firmware version. Use only as a guide and not as absolute values
In-Rush Power Consumption
