## Long description

The Atte AUPS-70 is a buffer SMPS power supply that provides a regulated 24V DC output with a maximum current of 3A. It is designed to supply continuous, stable power to low-voltage systems and to act as a backup source during mains interruptions. The unit integrates buffering capabilities to keep connected devices running until primary power is restored or a controlled shutdown is performed.
Advantages
The Atte AUPS-70 offers compact, efficient voltage regulation and built-in buffering to reduce the risk of data loss or device malfunction during short supply outages. Its 24V/3A output supports a range of security and communication equipment, while the switched-mode design ensures lower heat generation and higher conversion efficiency compared with linear supplies. The product is intended for straightforward integration into existing low-voltage installations.
Suitable for
Access control systems (electromagnetic locks, controllers)
Security and alarm panels
Communication and telemetry modules
Low-voltage industrial and automation devices
Backup power for networked electronics and sensors
Key specifications
Output voltage: 24 V DC
Maximum output current: 3 A
Output type: regulated DC with buffering capability
Supply topology: switched-mode power supply (SMPS)
Intended use: continuous supply with backup/buffering during mains interruptions
How to use
Install the Atte AUPS-70 according to local electrical codes and the installation guidelines of the equipment it will serve. Connect the AC input to the facility mains via an appropriate fuse or circuit protection, then connect the 24V DC output to the target devices observing correct polarity. Ensure ventilation around the unit to maintain operating temperature limits. If used as a backup, verify the buffer/backup functionality during commissioning and perform periodic checks to confirm reliable switch-over behavior in case of mains loss.
Usage recommendations
For reliable operation, pair the AUPS-70 with devices whose combined current draw does not exceed 3A and protect the AC input with a suitable fuse or circuit breaker. Avoid prolonged operation at maximum load to extend service life, and schedule occasional functional tests of the buffering feature to ensure proper response to power interruptions.
