TRIO Flatmount Gen 3 12V Power Supply

TRIO Flatmount Gen 3 12V Power Supply

TRIO's Gen 3 12V Power Supply plugs directly into the Gen 3 Starlink router and runs your dish straight off a 12V or 24V battery. No inverter needed. Powering Starlink through a large inverter wastes idle draw (30 to 50 watts on a 3000W inverter), which adds up to hours of lost battery life when you are off-grid. This power supply cuts that loss by converting your battery power directly to the voltage Starlink needs.

Simply unplug the 110V Starlink power supply and plug in our 336W power supply, then connect it to a 12V OR 24V power source (input voltage range is 10 to 30V). TRIO's converter boosts this to the 56V that the Gen 3 router and dish need. It also continuously regulates voltage, so the dish gets stable power even as battery voltage shifts. A small indicator light is built into the converter, making setup and install much easier by confirming the unit is powered and running.

After testing numerous power supplies TRIO finally had one manufactured overseas. To eliminate any concern about ripple voltage (and subsequent dropouts and/or reduced speeds), they install a capacitor as well as the appropriate barrel connector that works seamlessly with the Starlink Gen 3 router. Off-the-shelf converters did not hold up, so they built their own with the correct output, filtering, and connector for reliable Gen 3 operation.

Power consumption tested over 1 hour with constant upload/download internet: 63 Wh (4.5A at 13.8V). Actual draw varies with usage and environment.

NOTE: Using snow melt function draws an additional 120W and cannot be used with cigarette lighter plug as most vehicles have a 10A limit.

If wanting to extend the barrel connector length, TRIO recommends adding a barrel connector extension. For input power wiring, size the wire properly based on the added length and current.

Please select the appropriate connector for your application from the drop down: bare wire leads, ring terminals, or cigarette lighter plug (must be 15A or greater cig plug). Bare wire is ideal for custom installs. Ring terminals are ideal for direct battery connections. Cigarette plug is the easiest option with a properly rated outlet.

Important Information

Compatible with Starlink Gen 3, 4, and 4X Standard that use the Gen 3 router. Not compatible with the Starlink Mini, which already accepts 12V to 48V DC directly. For the Mini, use the Mini 12V DC Power Cable instead. Standard 4 uses the Mini Router and Standard 4X uses a different router and connector configuration that is not compatible. If you are unsure which router you have, compare it against the photos at starlink.com/specifications.

The unit ships pre-assembled and ready to install with your selected connection type. It is sold as a complete unit, so individual internal components and connectors are not available separately.

Troubleshooting. If your battery reads 12V but Starlink won't power on, the issue is almost always voltage drop under load rather than the power supply itself. A battery can show full voltage at rest and still sag once the dish starts drawing power. Check wiring size (the most common cause), state of charge, fuse condition, ground connections, connection quality, and any corrosion in the circuit. Testing directly from a known good battery helps isolate wiring problems.
