Power Supply Converter Module | Honeywell FS-TPSU-2430
The Honeywell FS-TPSU-2430 is a power supply unit module developed for Honeywell Fail Safe Controller (FSC) and Safety Manager systems. Designed for safety-critical industrial automation, this board-level converter steps up a nominal 24 VDC input to a regulated 30 VDC output at 1 A, delivering stabilized auxiliary voltage to safety instrumented system (SIS) rack electronics and field termination assemblies.
Voltage Conversion and Current Limiting
The FS-TPSU-2430 operates by converting a standard 24 VDC system bus voltage into a regulated 30 VDC power output, accommodating continuous current loads up to 1 A. Built-in current control mechanisms limit inrush current during initial power-up to 4 A or less while keeping short-circuit current capped under 3.3 A. This safeguard protects internal module components and downstream safety logic circuits from overcurrent damage or bus voltage dips.
System Integration and Thermal Management
Designed to mount directly within Safety Manager or FSC system chassis, the module maintains steady voltage conversion across an extended operational ambient temperature range of -5 to +70 deg C. Its compact rack-mountable form factor allows seamless integration alongside system I/O units, providing localized power regulation while maintaining electrical isolation from primary DC power distribution networks.
