Fonte de alimentação PULSAR PSB-12V7A 12V 7A – Módulo de saída DC

PULSAR PSB-12V7A is a compact 12 V DC power supply designed to deliver a continuous 7 A output for low-voltage electronic equipment. It provides a stable DC source for devices that require reliable, uninterrupted power and is suitable for installation where space is limited and standard terminal connections are preferred. The unit is intended for use with CCTV cameras, access control systems, alarm panels and other 12 V devices with combined current draw up to 7 A.

Advantages

The power supply offers regulated 12 V output with sufficient current capacity for multiple small devices or a single higher-draw unit. Its compact form factor facilitates installation in cabinets or behind panels, while standard screw terminal connections simplify wiring and integration into existing systems. The design focuses on continuous operation and thermal stability to maintain consistent voltage under typical load conditions.

Suitable for

• CCTV camera systems and video recorders
• Access control units and electric locks
• Alarm control panels and sensors
• Small networking equipment and auxiliary 12 V devices

Key specifications

• Output voltage: 12 V DC
• Maximum output current: 7 A continuous
• Output power: rated for applications up to the combined 12 V 7 A load
• Connection type: standard screw terminals for DC output wiring
• Form factor: compact enclosure for mounting in equipment cabinets or panels
• Intended operation: continuous low-voltage DC supply for electronic devices

How to use

Install the power supply in a well-ventilated location inside an appropriate enclosure or equipment cabinet. Connect the AC input according to local electrical regulations and wire the 12 V DC output to the load using the provided screw terminals, observing correct polarity. Verify that the total current draw of connected devices does not exceed 7 A. After connections are secure, power on the unit and confirm stable 12 V output with a suitable meter before finalising the installation.

Recommendations

Place the unit away from heat sources and moisture, ensure adequate ventilation around the enclosure, and routinely check terminal tightness and output voltage. For systems with loads close to the maximum rating, allow for margin to accommodate startup currents and avoid continuous operation at the absolute limit.
