Switched-Mode Power Supply PULSAR PSB-12V10A 13.8V 10A, 12V DC output, 10 A

PULSAR PSB-12V10A is a switched-mode power supply that delivers a stable 12 V DC output with a nominal current of 10 A and a regulated/charging mode at 13.8 V. The unit is designed for continuous low-voltage power delivery in systems requiring reliable DC supply and battery charging capability. Its compact construction and efficient switching topology make it suitable for wall- or cabinet-mounted installations where steady voltage and current are needed for connected devices.

Advantages

The power supply provides precise voltage regulation and a dedicated charging mode at 13.8 V for battery support, ensuring connected equipment remains operational during mains fluctuations. Its switched-mode design increases energy efficiency and reduces heat generation compared with linear alternatives. The device’s compact footprint and standard DC output simplify integration into CCTV, access control and alarm system installations, while the 10 A output capacity supports multiple devices or higher-consumption loads.

Suitable for

• CCTV camera systems and video recording equipment
• Access control panels, electric locks and card readers
• Alarm panels, sensors and monitoring devices
• Battery-backed installations requiring regulated charging
• General 12 V DC devices in small commercial or residential setups

Key specifications

• Output voltage: 12 V DC nominal, 13.8 V charging/regulated mode
• Maximum output current: 10 A
• Switched-mode topology for increased efficiency and lower heat
• Continuous operation suitable for powering and charging simultaneously
• Compact form factor suitable for mounting in cabinets or enclosures

How to use

Install the unit according to local electrical regulations, mounting it securely in a ventilated location. Connect the AC mains supply to the input terminals with appropriate fusing and protective measures. Attach the 12 V DC output to the load, observing correct polarity. If battery backup is required, connect the battery to the designated charging terminals and verify the charging mode at 13.8 V. After connections are complete, power the unit and check output voltage and current under load to confirm proper operation.

Usage recommendations

For reliable long-term operation, place the power supply in a dust-free, ventilated area and avoid covering ventilation openings. Use appropriately sized wiring to minimise voltage drop at 10 A loads and install fuses or circuit breakers on both AC and DC sides per applicable codes. Periodically verify charging voltage and battery condition where used for backup to ensure sustained performance.
