Key Features
- Compatible with Altronix Systems: This power supply (model SMP3) can convert low-voltage AC from 16VAC to 28VAC into continuous power supply, including 24vdc power supply, 6VDC, and 12VDC, all delivering 2.5A current. As a reliable 24 volt power supply, it meets the power needs of devices in multiple scenarios such as security and access control
- Compatible with Altronix Battery Solutions: It features a sealed lead-acid or gel-type battery backup function, with a maximum charging current of 350mA. When AC is cut off, it supports automatic switching to battery power—this ensures the 24v power supply remains stable and the system operates uninterrupted, making it a dependable 24v dc power supply for critical applications
- Installation Specifications: It offers two installation options: Snap Track and DIN Rail (some require additional ordering). Built-in electronic voltage regulation and filtering circuits guarantee stable output, which is essential for maintaining consistent performance of the 24vdc power supply and preventing voltage fluctuations that could affect connected devices
- Equipped with LED Diagnostic Function: With visual fault diagnosis logic, it intuitively displays the operating conditions of the power supply—including normal operation, short circuit, overload, and battery undervoltage—through different state combinations of red (DC) and green (AC) LED lights. This helps users quickly identify issues with the 24 volt power supply and ensure timely maintenance
- Peripheral Accessory Ecosystem: It uses 18AWG wires to connect batteries and transformers of 40VA and above, which is crucial for matching different voltage outputs like the 24v dc power supply. It also complies with national electrical codes and local regulations, ensuring the safe and compliant installation of the 24v power supply in various environments
