Switching mode buffer power supply HPSB 13.8V/3A/7Ah HPSB-12V3A-B

Reliable power supply for security and automation systems

Buffered impulse power supply HPSB-12V3A-B from Pulsar is a solid solution providing uninterrupted power to devices requiring stabilized 13.8 V DC voltage. It is ideal for monitoring systems, access control, alarm systems and home automation applications. The device is designed to operate in both buffer and emergency modes, guaranteeing continuous operation even in the event of a mains power failure.

This power supply features high efficiency (87%) and the ability to connect a 7Ah battery, providing long-lasting power backup. The metal housing (RAL9003 – white color) protects the internal components and ensures the durability of the device. Additionally, the power supply has protections against short circuit (SCP), overload (OLP), overvoltage (OVP) and excessive battery discharge (UVP), which increases safety and protects connected devices. A built-in tamper switch protects against opening the housing.

Versatility and easy installation

The design of the power supply allows for surface mounting, and the presence of a distance from the ground facilitates cabling. An LED optical indicator informs about the operating status of the device. The ability to lock the housing with screws (or a lock) further protects against unauthorized access.

Key features and benefits:

• Stable output voltage: 13.8 V DC with adjustable range of 13.5-14 V DC, ensuring optimal operation of connected devices.
• High efficiency: 87% translates to lower energy consumption and less heat loss.
• Buffer and emergency operation: The power supply automatically switches to emergency mode in the event of a mains power failure, using the energy stored in the battery.
• Protections: A comprehensive set of protections protects devices from damage caused by short circuit, overload, overvoltage and battery discharge.
• Battery space: Built-in space for a 7Ah battery allows for extended system runtime after a power outage.
• Solid construction: Metal housing provides durability and resistance to mechanical damage.
• Easy installation: Surface mounting simplifies installation in various locations.
