R1S12-2405-R

Product Overview

The Recom Power R1S12-2405-R is a surface-mount, isolated DC-DC converter module in the ECONOLINE R1S (1W) series. It accepts a 21.6 V to 26.4 V input and provides a single 5 V output at up to 200 mA, delivering 1 W of output power. The module specifies 1 kV isolation and includes short-circuit protection, operating over -40°C to 100°C with 78% efficiency. Its 12-SMD package with 10 leads measures 0.60 in L x 0.42 in W x 0.28 in H (15.2 mm x 10.7 mm x 7.0 mm).

Key Features

• Isolated module DC-DC converter with one output
• 5 V output at 200 mA for 1 W power
• Input range 21.6 V to 26.4 V
• 1 kV voltage isolation
• Short-circuit protection (SCP)
• Operating temperature -40°C to 100°C
• 78% efficiency
• Surface-mount 12-SMD module with 10 leads
• Size 15.2 mm x 10.7 mm x 7.0 mm

Applications

• Commercial information technology equipment boards needing an isolated 5 V auxiliary rail
• Surface-mount electronic assemblies requiring compact 1 W DC-DC conversion
• Board-level subsystems that need isolation between a 21.6 V to 26.4 V input and a 5 V output

Design & Procurement Notes

When integrating the R1S12-2405-R, designers should account for its 1 W maximum output and 200 mA current limit when sizing downstream loads. The 21.6 V to 26.4 V input window requires the upstream supply to remain within this range under operating conditions. The 1 kV isolation and SCP feature provide input/output separation and short-circuit protection, while the surface-mount 12-SMD module, 10-lead footprint, and 15.2 mm x 10.7 mm x 7.0 mm height affect PCB layout and mechanical clearance. The -40°C to 100°C operating range and 78% efficiency should be included in thermal and power budget calculations.
