RECOM DC-DC Converter, 89% Efficiency, 1000μF Maximum Capacitive Load - RI3 Series - RI3-1212S

Wishing for stable power distribution to components on your circuit boards? Let this DC-DC converter from RECOM make your dreams come true. It lets you eliminate noise and ripple from 12V DC voltage inputs to give you the stable 12V DC output needed by small devices like relays. Thanks to its non-conductive plastic casing, you won't be shocked by electrical hazards during installation or maintenance. The unit's high efficiency of 89% means it lets you power through your tasks with minimal energy waste.

• Power rating of 3W for use in low-power applications

• Mean time between failures of 4,395,000 hours at +25°C for long-term operation

• Broad operating temperature range of -40°C to +85°C for use in challenging settings

Applications

• Laptop and desktop computers

• Production equipment

• Robotics and automation systems

How do I mount this DC-DC converter?

This converter comes with standard pinouts that you can solder directly onto your PCB for a secure fix that won't be loosened by vibration.

Is this DC-DC converter flame-resistant?

Yes, it stops burning in 10 seconds or less in the event of a fire, so it won't promote the spread of flames.

Recom RI3 Series Isolated DC-DC Converter

The RI3 series of isolated DC-DC converters from Recom have been designed for use within space-restricted applications. Designed for 3 W conversion applications, but have the same footprint as the Recom RI2 series 2 W converters.

The RI3 series also provides up to 3 k V dc I/O isolation, providing up to 90% efficiency making them suitable for a wide range of industrial applications.

Features and Benefits

•Industry standard pinout for easy installation.

•3 W in a SIP4 package.

•Wide operating temperature range of -40°C to 100°C.

•1 to 3 kV dc isolation.
