TRUNKGUARD TPS400 Fieldbus Power Supply

The TRUNKGUARD TPS400 Fieldbus Power Supply is for general purpose and non-incendive applications. Available models supply 350mA (for non-isolated, energy limited applications) or 500mA (for high current demand applications) of isolated, conditioned simplex (non-redundant) or duplex (redundant) power to up to four segments. The fieldbus power supply has a high-availability, modular design featuring modules that are hot-swappable with load-sharing in redundant pairs. This maintains power to the segment in the instance that one module in a pair needs to be removed. Additional features include a rugged industrial metal housing, optional pluggable surge protection, and multi-segment H1 connectors that deliver simple, error-free wiring to a DCS and reduce installation time. The TPS400 also has an economical Diagnostics Module (FDM252) option that provides a master alarm and LED-based alarms for segment noise, DC voltage levels and conditioner status faults.
