## Product-specific description

Use this Starlink Mini 12V DC Power Converter when you need to power a roof-mounted Mini from a leisure battery. It converts the battery supply to 30V DC, with a short output lead that stays close to the dish. Battery power needs an on/off control. The Mini uses battery energy while powered, even when nobody is browsing. This converter does not automatically turn off with the vehicle ignition. Switch its battery input off when it is not needed, or have a suitable ignition-controlled supply installed. See how to control power and protect your battery. What This Is For Connect the converter to a protected 12V leisure or house-battery circuit in a motorhome, campervan or boat. Mount it inside, close to a sealed roof or deck entry. Then secure the outdoor lead along its short route to the Mini. This keeps the battery wiring inside instead of leaving a loose cable hanging down the vehicle. For example, extend the battery feed through internal service spaces when the battery sits further away. Our Starlink Mini battery power guide shows the basic wiring and terminal-block connections. Starlink Mini 12V DC Power Converter: Key Features Direct DC supply: use a battery circuit without a 230V inverter feeding the Mini’s mains adapter. Compact housing: position the small finned unit near the cable entry, inside the vehicle or boat. Short output lead: keep the Mini connection local to the mounting position. Extendable battery feed: join the input wires to correctly sized extension wiring with rated terminals or crimp connectors. Solar-backed battery use: run from a battery recharged through a separate solar charge controller. Technical Specifications Converter type: non-isolated, constant-voltage DC-to-DC step-up converter Nominal input supply: 12V DC battery system Rated output voltage: 30V DC Maximum output current: 3.5A, supplier rating Maximum output power: 105W, supplier rating Housing dimensions: approximately 66 × 58 × 23mm, supplier dimensions Output lead length: approximately 98cm / 3.22ft, supplier specification Input connection: bare positive and negative DC wires Output connection: attached DC lead with Mini-style barrel plug and moulded sealing collar Brand: MotorCables SKU: MC-SLM-30V EAN: 5055646806979 Compatibility & Safety Preventing unwanted battery drain: isolate the converter's battery input to turn off both the converter and Mini. Switching only the output to the dish can leave the converter consuming some power. Do not rely on this converter as a low-battery protector. Manual control: use a suitably rated DC switch on the protected input circuit and turn it off when internet access is not needed. Ignition control: a suitable automotive relay can use an approved ignition-switched signal to switch a separately fused battery feed to the converter. The trigger signal controls the relay; it does not carry the converter's full input current. Ignition off then disconnects the converter and Mini. Parked use: use a leisure or house battery with a switch and suitable low-voltage disconnect, configured for that battery's chemistry and required reserve. Ignition-only control would also turn your internet off when you park. Ignition on does not necessarily mean the engine is running or charging the battery. Have the control circuit, relay, fuse and cable sizing matched to the vehicle and equipment. Starlink's Sleep Schedule can reduce power use, but it is not a battery cut-off. Relays, switches and battery-protection devices are not included. The battery is the source; the 30V output lead supplies the Mini. Check the converter’s marked input range against your battery’s charging and operating voltages. Also check output polarity, plug fit and cable routing before connection. Starlink lists a 12–48V DC input, rated at 60W, for Mini. A regulated 30V supply falls within that published voltage range. However, this is a third-party accessory, and testing with a Mini has not yet been completed. Fit a fuse near the battery supply and use cable and connections rated for the complete input circuit. The 3.5A output rating is not the battery-side fuse rating. Read our voltage-drop guide when planning longer battery feeds. Solar panels must charge the battery through an appropriate solar charge controller. Do not connect this converter directly to a bare solar panel. For longer parked use, preserve starting capacity if you use a vehicle’s starter battery. One converter with attached input wires and a DC output lead is included. The Mini, battery, fuse, extension wiring, terminals, cable-entry gland and mounting hardware are not included. The vehicle, yacht and battery images illustrate possible arrangements rather than a tested MotorCables installation. Pre-order at £34.99 including VAT. The first batch is on order, and the dispatch date is not yet confirmed. Final batch specifications, connector fit and operation will be checked before dispatch.
