Switching Power Supply PULSAR HPSB-12V3A-C 12V 3A

PULSAR HPSB-12V3A-C is a compact switching power supply that provides a regulated 12 V DC output with a maximum current of 3 A. It is designed for stable low-voltage power delivery in small installations where reliable, continuous operation of connected devices is required. The unit converts AC mains input to a steady 12 V output while maintaining efficiency and thermal stability in a compact enclosure.

Advantages

This switching power supply offers stable voltage regulation and overload protection in a small footprint, making it suitable for installations with limited space. Its design emphasizes efficient conversion from AC to DC to reduce heat generation and energy loss. The product provides consistent current delivery up to 3 A, ensuring connected devices receive uninterrupted power under typical operating conditions.

Suitable for

• CCTV cameras and surveillance systems
• Access control panels and electronic locks
• Routers, switches and small network devices
• LED lighting strips and low-voltage lighting modules
• Other 12 V electronic equipment requiring up to 3 A

Key specifications

• Output voltage: 12 V DC regulated
• Maximum output current: 3 A
• Output power: up to 36 W
• Input: AC mains to switching converter
• Protection features: overload and short-circuit protection
• Form factor: compact enclosure suitable for small installations

How to use

Install the power supply in a dry, ventilated location away from direct heat sources. Connect the AC mains input according to local electrical regulations and verify input voltage compatibility before powering up. Connect the 12 V DC output to the device requiring power, observing correct polarity. After connection, power on the unit and check that the output voltage is stable and the load operates as expected. If the unit enters protection mode due to overload or short circuit, disconnect the load, resolve the fault and restart.

Usage recommendations

Use appropriate cable gauge for the supplied current to minimize voltage drop, and ensure secure, insulated connections. For continuous operation, allow adequate ventilation around the enclosure and avoid installing in sealed compartments. When powering multiple devices, verify total current draw does not exceed 3 A and consider a power supply with higher capacity for future expansions.
