R-78HB24-0.3 Description

Short technical summary and product information.

The R-78HB24-0.3 is a DC/DC converter from Recom Power designed as a linear regulator replacement. It delivers a regulated 24V output at 300mA (7.2W) with an input voltage range of 36-72V and absolute maximum of 75V. The converter achieves up to 96% efficiency at 36V input, reducing the need for heatsinks.

 

Key specifications include a typical quiescent current of 1mA, switching frequency of 120-800kHz, and output ripple of 20-60 mVp-p. Protection features include over-temperature protection (OTP) and short circuit protection (SCP). The device requires a minimum load of 2% (10mA recommended) and includes an internal 1µF input filter.

 

The converter is housed in a 3-SIP through-hole module measuring 11.5 x 8.5 x 17.5mm. It operates over a temperature range of -40°C to 85°C and is suitable for ITE (commercial) applications such as industrial 24V bus supplies, telecommunications, and battery-powered systems.
