Power supply PULSAR PSG2-12V2A 13.8V 2A enclosed desktop/installation

PULSAR PSG2-12V2A is a switched-mode power supply that delivers a stabilized DC voltage of 13.8V with a maximum current of 2A. Intended for installation inside equipment housings or as a desktop unit, this compact power supply provides steady power for devices that require slightly elevated 13.8V rails. The design supports continuous operation and includes regulation suitable for powering security systems, access control panels, small electronics and CCTV modules that operate at automotive-style or telecom-style voltages.

Advantages

The power supply features switched-mode topology for high efficiency, low heat dissipation and compact dimensions. It provides stable voltage regulation under varying load up to the 2A limit, improving reliability for connected devices. The enclosed construction is suitable for installation in equipment cabinets or use on a desk while minimizing exposure to dust and accidental contact. Its 13.8V output is convenient for systems that require slightly higher than nominal 12V for battery charging supervision or to compensate for cable voltage drop.

Suitable for

• Powering security alarm control panels and sensors
• Supplying access control systems and electric door locks
• Providing DC power to CCTV cameras and recorders
• Feeding small electronic modules and embedded devices
• Systems requiring battery float/charge supervision at ~13.8V

Key specifications

• Output voltage: stabilized 13.8 V DC
• Maximum output current: 2 A
• Switched-mode (SMPS) topology for improved efficiency
• Enclosed desktop/installation form factor suitable for equipment cabinets
• Continuous operation capability with thermal considerations

How to use

Install the power supply according to the mounting requirements of your enclosure or place it on a stable surface if used as a desktop unit. Connect the AC input to a compatible mains supply using the specified cable and connectors, then connect the DC output to the target device, observing correct polarity. Ensure the total load does not exceed 2A and confirm proper ventilation around the enclosure to avoid overheating during continuous operation. If used with rechargeable batteries, follow battery manufacturer guidelines for float/charge management and verify compatibility with a 13.8V float voltage.

Usage recommendations

For reliable long-term operation, keep the unit in a well-ventilated location, avoid exceeding the rated current, and use appropriate fusing or circuit protection on the DC output. Regularly check wiring connections and the operating temperature when powering loads near the maximum rating.
