RECOM Switching Regulator, 12 to 42V DC Input Voltage Range, 9V DC Output Voltage - R-78C-1.0 Series - R-78C9.0-1.0

Need a reliable way to control the output voltage of your industrial equipment? Use this switching regulator from RECOM. It steps down input voltages between 12 and 42V DC to a lower output voltage of 9V DC for use in low-power systems. Thanks to its high efficiency of 90 to 95%, it loses minimal power as heat, so there's no need to install a heat sink. This device has a wide operating temperature range of -40°C to +85°C, making it suitable for use in demanding environments. Built-in short circuit protection means you can rely on it to protect downstream devices against electrical damage.

Features & Benefits

• Non-conductive plastic case to reduce the risk of electric shocks during installation and maintenance

• Light weight of 2g to minimise strain on your equipment

• Mean time between failures of 8,600,000 hours at +25°C for long-lasting performance

Applications

• Aviation industry

• Consumer electronics

• Telecommunications systems

What's the load regulation of this unit?

This switching regulator has a load regulation of ±0.4%, meaning it maintains a constant output voltage for reliable performance.
