Power
Vehicle DC Power Supply
Vehicle power input for the Thor VM3 dock is 10V to 60V DC and is accepted without the
need to perform any manual operation within the Thor VM3 dock, see
12-48 VDC
Vehicles (10-60 VDC Direct Connection) . The dock provides a conditioned power output
for the Thor VM3. By using a specified DC/DC power supply, input voltage of 50-150V
DC can be accepted, see
60-144 VDC Vehicles (50-150 VDC Power Supply, Screws on
Top of Lid) or 60-144 VDC Vehicles (50-150 VDC Power Supply, Screws on Top of Lid) .
Power input is fused for protection and the fuse is externally accessible, see Fuse .
External AC Power Supply
If DC power is not available – for example, in an office environment – an optional exter-
nal Universal Input Power Supply can be used to convert AC wall power to an appropri-
ate DC level. AC to DC power input for the Thor VM3 is delivered to the dock via an
optional external power supply and adapter cable. See
External AC/DC Power Supply .
Uninterruptible Power Supply
The Thor VM3 contains an internal UPS battery.
The UPS battery is automatically charged when the Thor VM3 is placed in a powered
dock, provided the safe charging temperature conditions below are met.
When external power is removed, the UPS automatically powers the Thor VM3 with no
user intervention. When running on UPS power, the power management timeouts may
be different than when vehicle power is applied.
The UPS allows the Thor VM3 to continue operation when not mounted in a dock or
when the vehicle battery is being swapped. When fully charged the UPS battery is
designed to power the Thor VM3 for a minimum of 30 minutes at temperatures of -30ºC
(-22ºF) or greater.
If operating on UPS power and the UPS battery becomes critically low, the Thor VM3
performs a controlled shutdown.
If there is no external power available, there must be 35% or greater power in the UPS
battery or the Thor VM3 does not power on.
Caution: Vehicle DC power supply connections require a DC-compatible
Dock .
