RECOM RPA120H-RW

Dengrove Electronic Components has extended its portfolio of EN50155-compliant DC/DC converters by introducing the RECOM RPA120H-RW, which delivers up to 120W in the industry-standard half-brick footprint of 61.0mm x 57.9mm.

In addition to satisfying EN50155, the harmonised European standard covering electronic equipment for railway rolling stock, the RPA120H-RW also complies with the UL and IEC/EN 60950-1 industrial safety specifications and is therefore suited a wide range of communication, control and monitoring applications.

The single-output converter can be specified with either 12V, 15V or 24V output voltage, and has a wide 4:1input-voltage range spanning 53V to 154V. Tight output-voltage regulation, with ripple and noise below 100mVp-p, ensure stable power for sensitive equipment deployed in challenging environments. The output voltage can be trimmed by ±10% using external trim-up and trim-down resistors, or adjusted via remote-sense inputs.

Over-temperature, short-circuit, over-current and over-voltage protection are built in, and the converters also ensure user safety by providing 3kV isolation and meeting standards for reinforced insulation. All units come with RECOM’s three-year manufacturer’s warranty.

The units are supplied with an aluminium heatsink fitted, and are capable of operating with case temperature up to 100°C. They can be specified with an active-high or active-low control pin output, and also provide the option of output gating that provides a convenient means of powering-down the load to save energy while allowing fast wake-up from standby. Full-load efficiency of up to 88.5% minimises power dissipation when active.
