RECOM Switching Regulator, 17 to 72V DC Input Voltage Range, 12V DC Output Voltage - R-78HB Series - R-78HB12-0.5

Control the output voltage of your industrial equipment using this switching regulator from RECOM. It works by converting the input voltage supply into a suitable output voltage for the connected device. For versatility, this component has a broad input voltage range between 17 and 72V DC so you can use it in both low-voltage and high-voltage systems. Its efficiency rating of 89% means it produces minimal heat energy, eliminating the need for heat sinks and saving space on busy control panels.

Features & Benefits

• Wide operating temperature range between -40°C and +85°C to withstand demanding environments
• Non-conductive plastic body helps prevent electric shocks
• Low ripple and noise level of 20mV Pk-Pk for added efficiency
• Integrated short-circuit protection for durability

Applications

• Communications equipment
• Packaging industry
• Consumer electronics
• Aviation industry

How do I mount this switching regulator?

This device comes with through-holes in its body, meaning you can mount it without drilling holes in it.

How reliable is this regulator?

It has an output voltage accuracy rating of ±2% so only minimal errors will occur during a voltage conversion.
