The Recom R1SE Series is an economic E class DC/DC converter with no compromise in quality. These unregulated DC/DC converters have 1W power, 1000V dc isolation and 5V input output. The R1SE is used mainly in isolation for interfaces of bus systems, where an operating temperature of+85°C without de-rating is sufficient
The R1SE Series of DC/DC converters weights only 1 gram and can be positioned precisely and quickly with automatic placement equipment. The case has been designed so that potting is not necessary, although not potted the 100% lead free design enables this DC/DC converter to withstand all thermal cycling in the vapour phase solder processes.

1 : 1 input range
SMD package
Efficiency up to 75%
1k V dc isolation
Operating temperature from -40°C to +85°C

Having trouble using one power supply to feed two circuits that need to be kept apart? This DC-DC converter from RECOM provides a simple solution to your wiring woes. It has an input and output to link your circuits and an isolation of 1kV to ensure they're electrically separated for safety. The unit's light weight of 1g makes it a handy option for portable equipment. A power rating of 1W assures you that it's energy efficient and won't drain your device.

• Wide operating temperature range between -40°C and +85°C to handle harsh conditions
• Standard SMD package for easy surface mounting
• Short-circuit protection helps safeguard sensitive circuits from electrical faults

• HVAC equipment
• Motor control devices
• Industrial automation
• Telecommunications systems

This converter is unregulated, making it suitable to use in circuits with steady voltages. As it's unregulated, it doesn't need an optocoupler, so you can keep internal components to a minimum. This boosts reliability, giving the converter an expected maintenance-free run of 1,022,000 hours when it's used at ambient temperatures.
