9000311PWRSPLY – Power Supply, 9-60VDC, 60W
Connecting electrical cables to power sources
The DC-to-DC power supply is used to power certain vehicle-mount computers (VMCs) or to provide vehicle power to certain hand-held
computers (HHCs) when placed in a DC powered vehicle dock or cradle.
Specifications for electrical supply
Always observe input voltage range specified on the DC-to-DC power supply and the optional screen blanking box
Input Voltage
(for vehicle mounted terminals only).
Output Voltage
12 VDC ± 10%
Power
75 W
Tecton, MX9, MX3 Plus, MX7: Use a 5 A slow blow fuse.
Thor VX8, Thor VX9, Marathon: Use a 10 A slow blow fuse
Thor VM1, Thor VM2, Thor VM3: Use VM3055FUSE (or equivalent) to install the fuse as shown below:
• For 12VDC input, use the 10A fuse from the kit or a slow blow fuse that has a DC voltage rating greater than 12VDC.
Fuse
• For 24VDC input, use the 6A fuse from the kit or a slow blow fuse that has a DC voltage rating greater than 24VDC.
• For 36VDC input, use the 4A fuse from the kit or a slow blow fuse that has a DC voltage rating greater than 36VDC.
• For 48VDC input, use the 3A fuse from the kit or a slow blow fuse that has a DC voltage rating greater than 48VDC.
Screen Blanking Box: Use a 3 A fuse
Please refer to the appropriate wiring schematic on the following pages for wiring colors and connections:
Figures 1a and 1b – Thor VX8 and Thor VX9 Vehicle Mounted Computers
Figures 2a and 2b – Thor VM1, Thor VM2 and Thor VM3 Vehicle Mounted Computers
Figure 3 – Marathon Vehicle Dock
Figure 4 – MX3Plus, MX7, MX7 Tecton and MX9 Vehicle Mounted Cradles
For proper and safe installation, the input power cable must be connected to a fused circuit on the vehicle. This fused
Caution:
circuit requires a user supplied 5 or 10 Amp maximum time delay (slow blow, see table above for fuse rating) high
interrupting rating fuse. If the supply connection is made directly to the battery, the fuse should be installed in the
positive lead within 5 inches of the battery positive (+) terminal.
Caution
The VX power supplies are sealed per IPXX. Usage in areas where moisture can affect the power supply connections
should be avoided. The power supply should be mounted in a dry location within the vehicle or placed in a suitable
protective enclosure.
Caution:
For installation by trained service personnel only.
Warning:
Risk of ignition or explosion. Explosive gas mixture may be vented from battery. Work only in well ventilated area.
Avoid creating arcs and sparks at battery terminals.
