Buffered Switching Power Supply PULSAR PSCLB13830 — 13.8V 3A, IP67 Rated

PULSAR PSCLB13830 is a buffered switching power supply that provides a stabilized 13.8V DC output with a maximum current of 3A and IP67 ingress protection. The unit is built for continuous operation and for situations where backup buffering is required; its sealed housing protects internal electronics from dust and water, making it suitable for outdoor or harsh environment installations. The supply integrates switching regulation to maintain voltage stability under varying loads and includes features common to buffered supplies to support connected low-voltage devices reliably.

Advantages

The compact, sealed construction offers IP67-rated protection against dust and temporary immersion in water, extending application possibilities to external enclosures and semi-exposed equipment. Switching regulation ensures efficient power conversion and reduced heat generation compared with linear alternatives. Buffered operation provides temporary power hold-up to prevent interruptions during brief supply disturbances. The design supports stable voltage output under varying load conditions and reduces the need for frequent maintenance in dusty or wet locations.

Suitable for

• CCTV camera systems and video surveillance installations
• Intruder alarm panels and security system modules
• Access control units, electric strike controllers and readers
• Small telecommunications and network devices requiring 13.8V DC
• Outdoor cabinets, gate controls and other semi-exposed equipment

Key specifications

• Output voltage: stabilized 13.8 V DC
• Maximum output current: 3 A
• Power type: buffered switching (DC regulated with buffering capability)
• Ingress protection: IP67-rated sealed housing
• Intended installation: indoor or outdoor/semi-exposed locations
• Primary application: continuous and backup power for low-voltage security and access devices

How to use

Mount the power supply in a location that meets ambient temperature and ventilation recommendations from the system designer and provides secure cable routing. Connect the primary AC or DC input according to the installation manual or wiring diagram, then connect the 13.8V DC output to the load, observing correct polarity. If buffering or battery backup is used, connect batteries per the manufacturer instructions and verify charging and cut-off behavior before commissioning. Perform basic functional checks to confirm stable output voltage under expected load conditions.

Usage recommendations

Place the unit inside an appropriately rated enclosure if it will be exposed to prolonged direct weather or mechanical risk, and route cables through sealed glands to preserve IP67 durability. Regularly inspect cable entries and mounting seals during preventive maintenance, and verify output voltage under load periodically to ensure reliable operation of connected CCTV, alarm or access control equipment.
