RECOM Switching Regulator, 87% Efficiency, 3,875,000h MTBF - R78E Series - R-78E3.3-1.0

Choose this switching regulator from RECOM to deliver a stable output voltage supply to your industrial equipment. It works by converting a higher input voltage input to a lower output needed by voltage-sensitive devices. The unit has a wide input range between 7 and 28V DC, which is stepped down to a reliably steady 3.3V DC. For safety, the regulator comes with built-in short-circuit and overcurrent protection. This means you can rest assured it'll help prevent system downtime caused by surges or other current malfunctions.

Features & Benefits

• Non-conductive black plastic case offers protection from electric shocks

• Efficiency rating of 87% minimises energy wasted as heat

• Pin-out compatibility with linear regulators from the LM78XX range for versatility

• Pre-drilled holes in body for hassle-free mounting

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

Applications

• Railway equipment

• Security systems

• Robotics

• Household appliances

• Automotive engineering

How long will this regulator last?

This switching regulator has a mean time between failures of 3,875,000 hours, so you can rely on it for long-term performance.
