Power supply (desktop) PULSAR PSD12070 — switched-mode 12V 7A for CCTV

Desktop switched-mode power supply PULSAR PSD12070 provides a stabilized 12 V DC output with a maximum current of 7 A, tailored for CCTV systems and other low-voltage surveillance equipment. The unit is intended for continuous operation and delivers regulated voltage to cameras, recorders and peripheral devices. Its compact desktop form factor allows placement on a shelf or inside an equipment rack where a reliable 12 V supply is required.

Advantages

The power supply offers stabilized output voltage and current protection suitable for continuous powering of surveillance devices. Its switched-mode design ensures efficient energy conversion and reduced heat generation compared with linear supplies. The compact desktop enclosure simplifies installation and service access while providing steady DC power for multiple CCTV components. The device includes built-in protections to maintain safe operation under typical load conditions.

Suitable for

• Powering analog and IP CCTV cameras that require 12 V DC
• Supplying digital video recorders (DVR/NVR) and peripheral devices
• Low-voltage surveillance accessories such as IR illuminators and sensors

Key specifications

• Output voltage: 12 V DC regulated
• Maximum output current: 7 A
• Supply type: switched-mode (SMPS)
• Intended operation: continuous/24-hour use
• Form factor: desktop enclosure suitable for shelf or rack installation
• Protection features: stabilized output with overload/short-circuit protection (built-in)

How to use

Connect the power supply to AC mains according to the local voltage and safety standards, then attach the 12 V DC output to the positive and negative inputs of the camera or device, observing correct polarity. Verify that the combined current draw of connected devices does not exceed 7 A. After connection, check output voltage at the device terminals to confirm proper regulation before leaving the system in continuous operation. Periodically inspect the unit and connections for dust accumulation and secure terminals.

Usage recommendations

Install the unit in a well-ventilated location away from direct heat sources and moisture. Use appropriately rated cables and connectors to minimize voltage drop over longer runs. For installations near the device current limit, allow headroom and avoid loading the supply continuously at its maximum rating to extend service life. Observe grounding and electrical safety regulations when integrating with CCTV systems.
