Honeywell FS-TPSU-2430 DC/DC Power Converter
The FS-TPSU-2430 is a high-reliability DC/DC power converter designed for Honeywell Safety Manager and Fail-Safe Controller (FSC) systems. Accepting a 24 VDC nominal input (18 to 36 VDC), it delivers a regulated 30 VDC output at 1 A to supply field termination assemblies (FTAs) and analog input modules such as the TSAI-1620m.
Power Conversion & Circuit Protection
The converter utilizes a switching architecture with an operating frequency greater than 25 kHz, achieving efficiency above 75%. It features built-in output overvoltage protection, short-circuit current limiting under 3.3 A, and isolated power distribution to prevent ground loops and shield central control electronics from field transients.
Mechanical & Mounting Configuration
Housed in a compact enclosure measuring 150 x 70 x 62.3 mm, the module mounts directly onto standard TS32 or TS35 x 7.5 mm DIN rails. The fanless natural convection cooling profile and extended operating temperature range support continuous deployment inside industrial control cabinets.

Frequently Asked Questions
Q: What is the primary function of the FS-TPSU-2430 in Safety Manager systems?A: The module converts a standard 24 VDC system bus voltage into a regulated, isolated 30 VDC loop power supply for field termination assemblies and associated analog transmitters.
Q: How does the unit protect against field short-circuit conditions?A: Internal current-limiting circuitry clamps output current below 3.3 A during a short circuit, preventing thermal damage and resuming normal 30 VDC operation automatically once the short is cleared.
