Weidmuller’s modular Uninterruptible Power Supplies (UPS) series is designed to offer secure and reliable protection against incoming power faults for 24 V dc applications. The modular UPS line includes control units, buffer modules and battery modules. The control units feature status relays for status monitoring, and provide direct switchover to the battery modules when a supply outage is detected, and automatic reconnection to the load when power recovers. The control unit, together with the battery module and power supply, offers a complete, scalable dc UPS system for loads up to 40A and with batteries capacities up to 17 Amp-hours. The buffer module offers a solution for bridging short-term power supply failures for dips of up to 100 ms. 

Weidmuller’s UPS system features a variety of configurations and options that enable users to size the system to meet their application needs. With accessories that include diode modules, buffers and capacity modules, it offers security and redundancy options for protection of their critical loads. Features include status outputs to update the user, and temperature-optimized charging to maximize battery life and system reliability. Approvals include TUV, cULus, CE and GL.
