Overview
The Ubiquiti EP-54V-150W-DC is a 54V 150W DC/DC power supply module designed for the EdgePower modular power system. It accepts a 22–60V DC input and provides a regulated 54V DC output through the EdgePower system's DC terminal block. The module can be used as a primary or auxiliary DC power supply, or as a backup PSU, and a second 150W module can increase the EdgePower system's total output capacity to up to 300W.
DC/DC Power Conversion
The EP-54V-150W-DC converts an input voltage in the 22–60V DC range to a 54V DC output with up to 150W of available power. This DC/DC design allows the EdgePower platform to operate from suitable external DC power sources instead of requiring an AC input module.
EdgePower Modular Design
The module is designed for installation in the Ubiquiti EdgePower EP-54V-150W chassis. The EdgePower platform provides two PSU module bays, allowing a second 150W module to be installed for increased total output capacity or configured as a spare/backup module.
Lead-Acid Battery Support
The EP-54V-150W-DC includes charging and discharge protection for 2-, 3-, and 4-series lead-acid battery configurations. Ubiquiti specifies different maximum charging and discharge protection voltages for each supported battery series configuration.
Battery Charging Parameters
For 2-series lead-acid batteries, the maximum charging voltage is 26.8–27.5V with a 0.3A charging current and a 21.5V discharge protection threshold. For 3-series configurations, the corresponding values are 40.2–41.2V, 0.3A, and 32V. For 4-series configurations, the values are 53.6–55V, 0.2A, and 43V.
Protection and Status
The module includes ESD/EMP protection rated at ±8kV through air and ±6kV through contact. A system On/Off LED provides local operating-status indication.
Key Features
- 54V DC output with up to 150W power capacity
- 22–60V DC input range for DC/DC operation
- Designed for the Ubiquiti EdgePower EP-54V-150W system
- Supports 2-, 3-, and 4-series lead-acid battery charging and discharge protection
- Can be used as a primary, auxiliary, or backup PSU module
DC Supplies Product Note
The EP-54V-150W-DC is a DC-input module rather than an AC mains power supply. When selecting the upstream DC source, its 22–60V input range should be observed. For battery-backed deployments, the supported 2-, 3-, and 4-series lead-acid configurations and their specified charging and discharge thresholds should also be considered.
