Traco Power Switching Regulator, SMD-10 Format, Level 1 Moisture Sensitivity - TSRN-1SM Series - TSRN 1-2433SM

Efficiently step down direct current with this switching regulator from Traco Power. It's a handy option for turning inputs between 4.6 and 42V DC into ±3.3V DC outputs needed to energise your low-powered machinery. Thanks to an efficiency rating of 88%, you can trust it converts power with minimal waste. A light weight of just 1.7g minimises strain on your setup, while neat dimensions of 15.2 (L) x 9.3 (W) x 7.6mm (D) ensure you can fit this little gadget into busy systems.

Features & Benefits

• Mean time between failures of 14 million hours for dependable long-term performance
• ±0.2% line regulation and ±0.6% load regulation mean you get a consistent power supply
• UL 94-V0-rated housing self-extinguishes within 10 seconds in the event of a fire
• Remote on/off function for convenient long-distance control

Applications

• Industrial automation
• Textile manufacture
• Process control

Does this device perform reliably in harsh industrial conditions?

Yes. This switching regulator gets on with its job in a temperature range between -40°C and +85°C, so it's ideal for use in challenging settings.

Do I need to fit a heatsink with this switching regulator?

As it produces minimal waste heat, it's able to stay cool through natural convection, so there's no need for a heatsink.
