Buffered Power Supply Delta PMU-13V155WCCA — PMU series, 13 V output, 155 W

Delta PMU-13V155WCCA is a buffered power supply from Delta's PMU series that delivers a regulated 13 V DC output with up to 155 W continuous power. Designed for systems that require stable DC voltage and buffering capability, this unit integrates protection and voltage regulation features suitable for industrial installations, security equipment, telecommunications modules and embedded electronics. The construction and thermal behaviour are optimized for rack- or chassis-mounted applications where predictable power delivery is required.

Advantages

The buffered design provides hold-up capability and reduces voltage sag during transient loads, ensuring more consistent operation of connected electronics. Built-in regulation maintains the 13 V output within specified limits under varying input and load conditions. Compact physical dimensions and conservative thermal management allow installation in confined spaces while preserving reliability. The unit is compatible with common mounting and cabling practices used in control cabinets and communications enclosures.

Suitable for

• Industrial control systems and PLC power feeding
• Security and access control equipment
• Telecommunications and networking devices
• Embedded electronic assemblies and edge devices

Key specifications

• Output voltage: 13 V DC nominal
• Maximum output power: 155 W continuous
• Buffered power topology providing transient hold-up
• Voltage regulation to maintain output under load variation
• Thermal design suitable for cabinet or chassis mounting

How to use

Install the power supply according to your system’s mechanical and electrical layout, ensuring adequate ventilation and secure mounting. Connect the incoming DC or AC supply and verify correct input polarity and voltage range before energising. Route output cabling to the load with appropriate cross-section and secure terminations to minimise voltage drop. If the system includes a backup battery or buffer module, follow the manufacturer’s instructions for integration and charging circuits. Perform initial power-up checks with a multimeter to confirm the 13 V output and monitor for stable operation under expected load conditions.

Usage recommendations

Use appropriate fusing and transient protection on both input and output lines, and ensure ambient temperature remains within the manufacturer’s specified range to maintain rated power. Periodic inspection of connections and ventilation paths will help preserve long-term performance and prevent overheating in enclosed installations.
