## Summary description

Delta PMU-27V155WCCA is a buffered (backup) power supply providing 27 V DC output and up to 155 W output power. Designed for uninterrupted power in industrial and telecommunications equipment, it supports buffering functions to maintain output during input disturbances and can integrate into PMU-based power systems for control and redundancy.

## Long description

Delta PMU-27V155WCCA is a buffered backup power supply delivering 27 V DC output with up to 155 W output power. Designed for continuous operation in industrial and telecommunications environments, this PMU-series unit provides stable DC voltage and buffering functions that help maintain load power during input disturbances or transient events. It is compatible with PMU-based power architectures and supports integration into redundant power systems for improved availability.
Advantages
The unit provides steady 27 V DC output and supports buffering to bridge short interruptions or to allow orderly transfer to alternate power sources. Its design targets industrial-grade reliability and integration ease into centralized power distribution racks or PMU systems. Built for continuous operation, the supply includes features that reduce the risk of output degradation under variable input or load conditions.
Suitable for
 Telecommunications equipment requiring uninterrupted 27 V DC supply
 Industrial control systems and automation racks
 Centralized power distribution and redundant PMU-based installations
 Network infrastructure and small data network cabinets
Key specifications
 Nominal output voltage: 27 V DC
 Maximum output power: 155 W
 Buffered (backup) function to maintain output during input disturbances
 Designed for continuous operation in industrial and telecom environments
 Compatible with PMU-series power system integration and redundancy setups
How to use
Install the power supply in a compatible PMU rack or designated mounting area following the system manufacturer's mechanical and electrical installation guidelines. Connect the input power source and the 27 V DC output to the load or distribution bus using appropriately rated cables and terminals. Configure any system-level monitoring or control connections provided by the PMU architecture to enable redundancy and buffering coordination. Verify polarity and grounding before first energizing, then perform initial power-up tests to confirm stable output and buffering behavior under expected load conditions.
Usage recommendations
Operate the unit in environments within the specified temperature and ventilation guidelines, and ensure regular inspection of connections and ventilation paths. For redundant or critical systems, combine the supply with a compatible PMU controller and matching modules to achieve expected buffering performance and system-level monitoring. When integrating into telecom or industrial installations, follow applicable safety standards and local codes.
