Redundant 100-240V AC power supply with automatic switchover ensuring uninterrupted 24/7 operation
- Wide input voltage range: 100–240 V AC
- Standby redundant AC power supply
- Automatic switchover upon primary power supply failure
- Seamless transfer with no service interruption
- Designed for telecom and critical infrastructure applications
- Supports high-availability architectures and continuous 24/7 operation
The RSPS-AC Standby Backup Module is designed for applications where continuous power availability is essential. Operating over a wide 100-240V AC input range, the module functions as a standby power supply, remaining inactive during normal operation while monitoring the main power source.
In the event of a failure, shutdown, or malfunction of the primary power supply, the module automatically and seamlessly takes over, supplying power to the system without interruption. This automatic switchover ensures uninterrupted operation and increased system reliability.
The RSPS-AC is a dedicated standby power supply developed specifically for DEVA products used in telecommunications and critical infrastructure environments. It is intended for systems where a redundant power source is available and continuous 24/7 operation is required. The design minimizes downtime, supports high-availability system architectures, and enhances overall operational resilience in demanding applications.
