PULSAR AWZG2-24V2A B Grade 2 is a buffer/backup power supply that provides a steady 24V DC output at up to 2A. It is intended for installations that require a reliable secondary power source to keep low-voltage devices running during mains interruptions. The unit integrates with security systems, access control panels, alarm devices and other equipment that operate from a 24V DC supply and need temporary autonomous operation while the main power is unavailable.
Advantages
The module delivers a regulated 24V DC output with a maximum current of 2A, ensuring consistent operation of connected devices during short-term power losses. Its compact design allows integration into standard electrical enclosures and system cabinets, facilitating neat installation and wiring. The buffer function supports seamless transition to backup power without manual intervention, reducing downtime for critical low-voltage devices. Built for professional installations, the unit focuses on stable output and compatibility with common access control and alarm system requirements.
Suitable for
- Security control panels and alarm systems that require a 24V backup source
- Access control units, electric strike or magnetic lock installations
- Low-voltage surveillance peripherals and sensor modules
- Small automation or monitoring devices powered by 24V DC
When it may not be suitable
This buffer power supply is not intended for high-power equipment; devices that require more than 2A at 24V will exceed the module's rated output and may cause overload. It is designed for short-term buffering during mains interruptions and not as a long-term replacement for a dedicated uninterrupted power supply (UPS) with extended runtime or large battery capacity.
Key specifications
- Output voltage: 24V DC
- Maximum output current: 2 A
- Function: buffer/backup power module for low-voltage devices
- Form factor: compact module suitable for installation in electrical/system cabinets
How to use
Install the unit according to local electrical regulations and the system wiring diagram. Connect the module to the mains power supply and link its 24V DC output to the positive and negative input terminals of the supported devices. Ensure correct polarity and secure terminal connections. The buffer operates automatically: when mains power is present it maintains charge or readiness, and it supplies the connected equipment from its backup output during interruptions. Regularly inspect connections and test operation as part of routine maintenance.
What to consider before purchase
- Check the combined current draw of all connected devices to ensure it does not exceed 2A.
- Verify that connected equipment requires a 24V DC supply and is compatible with buffered backup arrangements.
- Confirm available installation space in the cabinet or enclosure and mounting requirements.
Usage recommendations
For reliable performance, plan the connected load to stay below the 2A limit, follow recommended wiring practices, and include periodic functional tests of backup operation. Use appropriate fusing and circuit protection on the input and output sides as required by local regulations and the system design.
