What are the key features of R1SE-0505?

5 V nominal input (4.5 V to 5.5 V) with 5 V isolated output for one-to-one voltage conversion
Unregulated DC-DC module with up to 15% load regulation for light to moderate loads
SIP DIP-4 package enables easy through-hole board mounting and retrofitting
RoHS compliant (JESD-609 Code e1) for global market compatibility
Single-function isolated converter reduces design complexity in safety-critical circuits

What is R1SE-0505 used for?

The R1SE-0505 is commonly used to provide isolated 5 V power rails for RS-232 and RS-485 transceivers, industrial sensor interfaces, and PLC digital I/O modules where ground loop isolation prevents noise injection. Its compact SIP form factor also suits isolated gate driver supplies in motor control and power inverter designs requiring simple 5 V-to-5 V galvanic isolation.

Frequently Asked Questions

What input voltage range does the R1SE-0505 accept and how stable is its output?

The RECOM R1SE-0505 accepts an input voltage range of 4.5 V to 5.5 V with a nominal 5 V supply, and provides a 5 V isolated output with up to 15% load regulation. This makes it suitable for lightly loaded isolation barriers where tight regulation is not critical, such as RS-485 bus powering.

How does the R1SE-0505 achieve galvanic isolation, and what safety benefits does that provide?

The R1SE-0505 uses a miniature transformer inside the DC-DC module to achieve galvanic isolation between input and output. This 5 V-in to 5 V-out isolation eliminates ground loops and protects sensitive microcontrollers or MCU I/O pins from voltage spikes, common in industrial 24 V or motor-drive environments with long cable runs.

For high-volume procurement, what packaging options and lead times should be considered for R1SE-0505?

The R1SE-0505 is supplied in a SIP DIP-4 through-hole package and is RoHS compliant per JESD-609 Code e1. Buyers should confirm stock availability with distributors as RECOM DC-DC modules commonly have 8 to 14 week lead times; ordering in batches of 100 pieces or more often provides better pricing and supply continuity.

Can the R1SE-0505 be used to power RS-485 transceiver ICs in noisy industrial environments?

Yes. The R1SE-0505 provides a 5 V isolated output from a 5 V input, making it an ideal companion for RS-485 transceivers such as MAX485 or SN75176 that require an isolated 5 V rail to break ground loops in factory floors. The module's 1 W output power is sufficient to supply typical RS-485 line driver ICs drawing under 100 mA.
