Step down the supply voltage in your system with this DC-DC converter from RECOM. When supplied with an input voltage between 15 and 42V DC, it produces the constant output voltage of 12V DC needed by many low-power systems. As it has a broad operating temperature range between -40°C and +85°C, the device is suitable for use in demanding conditions. Its high efficiency level of 92 to 95% power loss is minimal, so you can be sure of reliable performance. Built-in short circuit protection helps to keep downstream equipment safe from electrical damage.

• Mean time between failures of 367,000 hours at +25°C ensures reliability with minimal maintenance
• Light weight of 4.5g for easy handling
• Free air convection cooling method helps prevent overheating, so there's no need for a heat sink

• Renewable energy systems
• Medical equipment
• Smart lighting
• Automotive industry

Yes, this DC-DC converter has compact dimensions of 23.7 (L) x 27.2 (W) x 10mm (H), so it takes up minimal space in your setup.
