Frequently Asked Questions
What is the isolation voltage and input range of the R1S-1209/HP-R?
The R1S-1209/HP-R provides 3 kV DC isolation with a 12 V nominal input accepting 10.8 V to 13.2 V, and delivers an unregulated 9 V output at up to 1W of continuous power for industrial and medical applications.
Which PCB footprint does R1S-1209/HP-R use and how does it compare to similar 1W converters?
R1S-1209/HP-R uses a SIP-5 through-hole package measuring approximately 11.6 mm × 6.1 mm × 7.5 mm, making it smaller than many 1W isolated modules and compatible with standard 0.1-inch pitch PCB holes for easy hand or wave soldering.
Can R1S-1209/HP-R power RS-485 transceiver circuits in industrial field devices?
Yes, R1S-1209/HP-R is commonly used to power RS-485 and RS-232 transceiver circuits, providing 9 V at 111 mA with 3 kV isolation to protect host microcontrollers from bus transients, ESD, and ground differences up to 3000 V in factory automation and building control systems.
What is the load regulation specification for R1S-1209/HP-R and does it affect sensitive analog circuits?
R1S-1209/HP-R has a maximum load regulation of 10%, meaning the 9 V output may vary up to 0.9 V between no-load and full-load conditions. For sensitive analog circuits requiring tighter regulation, a downstream LDO regulator should be added to maintain a stable supply within ±1% or better.
