RECOM Switching Regulator, 1μF Capacitor Internal Input Filter, 1 Output - R-78HB Series - R-78HB24-0.3

Boost power while cutting consumption with this switching regulator from RECOM. It's a versatile choice that converts input voltages between 36 and 72V DC to the smooth and steady 24V DC output needed by your system. The unit uses just 8W of power and has an efficiency of up to 96%, so you can say goodbye to external cooling devices. It also keeps electronic devices continuously protected against short circuits, curbing the risk of damage and downtime.

Features & Benefits

• Broad operating temperature range between -40°C and +85°C to handle demanding conditions
• Very high mean time between failures of 7.395 million hours for reliable long-term performance
• Non-conductive plastic casing prevents damage to circuits and makes the unit safe to handle

Applications

• Consumer electronics
• Aerospace equipment
• Telecommunication systems
• Automotive design

What type of linear regulator does this product replace?

This device can replace your old LM78xx-series linear regulator (such as 648-422) to give your equipment an upswing in energy efficiency.

Is there a shorter alternative to this unit?

Yes – if you need a shorter solution for your circuit, the L-version with 90° pins (672-7114) is your best bet.
