Fonte de alimentação comutada com buffer PULSAR HPSB-12V10A-C 12V 10A para videovigilância e sistemas de segurança

PULSAR HPSB-12V10A-C buffered switching power supply provides stable 12 V DC output with a maximum current of 10 A for continuous operation of CCTV cameras, digital recorders and other security devices. The unit is designed for use in surveillance and alarm installations where uninterrupted 12V power is required; its buffering capability keeps the output active during short mains interruptions. The compact form factor allows mounting in equipment racks or security enclosures and integrates with standard system wiring and protection components.

Advantages

The switching topology delivers efficient power conversion with reduced heat dissipation compared to linear supplies, while the buffering feature preserves device operation during brief power dips. Built-in protections help prevent damage from overload, short circuit and reverse polarity. The supply’s constant 12 V output and stable regulation support sensitive CCTV electronics and recording equipment, ensuring reliable performance in continuous 24/7 installations.

How to use

Install the power supply in a suitable ventilated enclosure or rack bay and secure it according to the mounting provisions. Connect the AC mains input to a properly rated circuit with appropriate overcurrent protection. Wire the 12 V DC output to cameras and devices using adequately sized conductors and observe correct polarity. Ensure any additional batteries or buffering modules are compatible before interconnection. After wiring, power up the unit and verify stable 12 V output with a multimeter and check connected devices for proper operation.

Recommendations

Place the unit in a dry, ventilated location away from heat sources and corrosive atmospheres. Use short, low-resistance cabling for the 12 V lines to minimise voltage drop. For installations with long cable runs or higher transient risk, combine the supply with local surge protection and consider battery backup sized to required hold-up time.
