For a compact conversion solution offering high power density, go for this 30W DC-DC converter from Traco Power. It takes inputs from a broad 2:1 range of 18 to 36V DC and steps them down to a closely controlled ±12V DC. This ensures you get a stable load for running sensitive battery-supplied devices. As this is a dual-output model, it's a great shout if you want to power two bits of connected kit at once. An impressive 89% efficiency means it creates very little heat waste, so there's no need for a heatsink or fan to keep it cool.

• 1.5kV DC isolation, so it's a safe bet for shielding you and your equipment from electrical spikes or surges
• Mean time between failures of over 550,000 hours makes it a long-lasting choice
• Flame-retardant potting material helps minimise the spread of fire
• Output voltage adjustable with ±1% accuracy for close load control
• Space-saving, at just 1.6 x 2"

• Industrial automation
• Telecommunications hubs
• Distributed power systems

Thanks to a built-in filter on the input, the electricity drawn from your mains power is balanced to prevent EMI from causing issues. This ensures you get stable performance.
