RECOM DC-DC Converter, Isolated, 50mVp-p Output Ripple and Noise - RSO Series - RSO-1212S

Switch up the power supply in your circuit using this DC-DC converter from RECOM. When it receives an input voltage between 9V and 18V DC, it regulates it to a safe output voltage of 12V DC. You can rest assured that with its low output ripple and noise of 50mVp-p clamping down on electrical interference, the unit provides clean and clear signals. Thanks to this converter's built-in continuous short-circuit protection, there's minimal risk of irregular current flow throwing up any shocks or surprises.

Features & Benefits

• Serves as an isolating barrier, helping to prevent electrical hazards

• Wide operating temperature range between -40°C and +85°C for use in harsh industrial environments

• MTBF of 1,685,000 hours for longevity

Applications

• Electrical engineering

• Lighting fixtures

• Smartphones

• Communications equipment
