Buffered switch-mode power supply for built-in mounting PSB 13.8V/10A PSB-12V10A

Buffered power supply for monitoring and security systems

This Pulsar PSB-12V10A switch-mode buffered power supply is a reliable solution for CCTV, SSWiN, alarm systems, video doorbells and other devices requiring a stable 12V DC power supply. Designed for built-in installation, it ensures continuous operation even in the event of a mains power failure, thanks to the ability to connect a battery. This is an ideal solution for both professional installers and end users who value safety and comfort.

Versatility and flexibility

The power supply offers a wide range of input voltage (200-240V AC) and adjustable output voltage (13.5-14.4V DC), allowing it to be adapted to various installation requirements. The ability to select the battery charging current (1A or 4A) increases its functionality and allows for optimization of system operation. The total current efficiency is 10A, and depending on the set battery charging current, the available output current is 9A (when charging 1A) or 6A (when charging 4A).

Safety and protection

The PSB-12V10A is equipped with a number of protections that protect both the powered devices and the power supply itself: short-circuit (SCP), overload (OLP), overvoltage (OVP) and reverse battery connection. Additionally, the control of the battery charging process ensures its proper operation and extends its lifespan. Optical LED signaling informs about the operating status of the power supply - the presence of AC voltage, DC voltage and battery charging process.

Key features:

• High efficiency: 87% – minimizes energy losses and ensures stable operation.
• Modular design: facilitates installation and integration with the system.
• Adjustable output voltage: allows precise adjustment to device requirements.
• Charging current selection: optimizes battery operation depending on needs.
• Complete protection: protection against short circuit, overload, overvoltage and reverse battery connection.
• LED indication: quick information about the power supply operating status.
• Dimensions: 199 x 110 x 50 mm – compact size makes it easy to install in a limited space.
• Weight: approximately 0.67 kg - lightweight design makes installation easier.

The power supply is intended for operation in closed rooms at temperatures from -10°C to +40°C and relative humidity up to 90% without condensation. Remember to use a protective conductor due to protection class I.
