Buffered Switch-Mode Power Supply PULSAR PSCLB13820 13.8V 2A IP67

Buffered switch-mode power supply PULSAR PSCLB13820 delivers a regulated 13.8V DC output with up to 2A continuous current in an IP67-rated housing. Designed for use as a backup or continuous power source, the unit provides stable voltage for security systems, access control panels and telecom devices. The buffered design maintains output during short mains interruptions while integrated protection features guard against overload, short circuit and thermal stress. The compact, weatherproof enclosure allows installation in exposed or industrial environments where dust and water resistance are required.

Advantages

The PULSAR PSCLB13820 combines switch-mode efficiency with buffering capability to ensure consistent 13.8V output under variable input conditions. Its IP67 enclosure provides reliable protection against dust ingress and temporary immersion in water, enabling outdoor or harsh-environment deployment. Built-in protection functions and thermal management reduce the risk of damage from overloads and short circuits, while the compact footprint facilitates installation in limited spaces.

Suitable for

• Security and alarm control panels
• Access control and door entry systems
• Telecom equipment and network devices requiring stable 13.8V supply
• Outdoor or industrial installations exposed to dust and moisture
• Backup power for low-current devices during mains interruptions

How to use

Install the unit in a suitable location that meets the IP67 environmental requirements, ensuring secure mounting and correct orientation. Connect the mains input according to local electrical standards and wire the DC output to the load, observing correct polarity. Verify the output voltage under no-load and nominal-load conditions. If used as a backup source, configure any external batteries or supervision interfaces in accordance with system requirements. Follow all applicable safety and installation regulations when connecting to security, access control or telecom equipment.

Usage recommendations

For reliable long-term operation, mount the power supply where it is protected from prolonged immersion and extreme temperatures. Ensure ventilation around the housing to aid thermal management, avoid running the unit continuously at its maximum rated current, and periodically inspect cable glands and seals to maintain IP67 integrity.
