Honeywell FC-PSU-UNI2450 CCV2 Power Supply Unit

The Honeywell FC-PSU-UNI2450 CCV2, also cataloged as the FC-PSU-UNI2450 Power Supply Unit, operates as a dedicated hardware component for 24 VDC output bus conversion and power conditioning within Honeywell Safety Manager and industrial control platforms.

Hardware Specifications

Channel-to-Channel Isolation & 4-20 mA HART Loop Protocol

The internal switching architecture incorporates isolation transformers and output filtering stage networks to suppress electrical common-mode transients and ground noise propagation across downstream I/O racks. Low output ripple characteristics deliver clean DC power distribution, eliminating supply-induced measurement drift across connected 4-20 mA HART loop protocol transmitters. High dielectric isolation safeguards field instrument channels from utility-side AC voltage fluctuations and cross-talk interference.

Frequently Asked Questions

Q: What input frequency range is supported by the AC input stage of the FC-PSU-UNI2450 CCV2?

A: The line input circuitry operates across standard AC input frequencies ranging from 47 to 63 Hz.

Q: What is the continuous DC output power capacity provided by the unit?

A: The module delivers a regulated 24 VDC output at up to 2.5 A continuous current, achieving energy conversion efficiency greater than 88%.

Q: Does the module consume power when operating under no-load conditions?

A: Yes, static power dissipation under zero-load conditions is rated at 13 W.

Field Installation Guidelines

1. Mount the unit securely inside the cabinet enclosure using designated panel or rack rail hardware.
2. Verify that line AC power sources are de-energized prior to connecting primary AC terminal connections.
3. Observe correct polarity when connecting 24 VDC output distribution cables to field rack busbars.
4. Route primary AC input wiring through dedicated channels separated from sensitive low-voltage DC signal cables.
5. Securely bond the main chassis earth terminal directly to the enclosure grounding rail to maintain noise rejection.
