Power Supply PULSAR PSD12050 12V 5A switching power supply for CCTV and low-voltage devices

PULSAR PSD12050 is a compact switching power supply that delivers stable 12 V DC output with a maximum current of 5 A. Designed for continuous operation, the unit is intended to power CCTV cameras, access control modules, sensors and other low-voltage devices that require a reliable, constant DC source. The housing and connector layout support wall- or rack-mounted installations in surveillance and access-control environments.

Advantages

The switching topology provides efficient voltage conversion with reduced heat generation and compact dimensions. Built-in protection mechanisms guard against typical electrical faults and help maintain uninterrupted device operation. The unit’s 12 V / 5 A rating supports multiple small devices or a single higher-load camera while keeping output voltage within common tolerances for CCTV and electronic access equipment.

Suitable for

• Powering analog and IP CCTV cameras requiring 12 V DC
• Supplying access control readers, electromagnetic locks and door controllers
• Feeding sensors, alarm panels and low-voltage automation modules

Key specifications

• Output voltage: 12 V DC
• Maximum output current: 5 A
• Output power: up to 60 W
• Type: switching (SMPS) power supply
• Intended installation: wall- or rack-mounted setups
• Continuous operation suitable for surveillance systems
• Included protections: overcurrent, overvoltage and short-circuit protection (typical for this class)

How to use

Install the unit in a dry, ventilated location that prevents overheating and allows access to the input and output terminals. Connect the mains input according to local electrical regulations and ensure correct grounding where required. Use appropriately rated DC cables to connect the 12 V output to cameras or other devices, observing polarity. Verify total current draw of connected devices does not exceed the 5 A rating and leave a safety margin for inrush currents. After connections, power on the supply and confirm stable 12 V output before finalizing cable routing and mounting.

Usage recommendations

For reliable long-term operation, keep ambient temperature within the manufacturer’s specified range, avoid enclosing the unit in tight, unventilated spaces, and regularly inspect wiring and terminal connections. When deploying multiple devices, calculate cumulative current consumption and, if necessary, use additional power supplies or distribution solutions to prevent overload.
