Product Description
The 3500/15 125840‑01 is a high‑voltage AC power input module used in a modular monitoring rack system. Mounted on the left side of the rack in a half‑height slot, it accepts 175–264 VAC and supplies regulated DC power to the entire rack. It features robust over‑voltage protection and is designed to operate reliably across industrial temperature ranges. It supports a dual‑supply redundancy setup, allowing seamless failover if the primary supply is removed or fails—ensuring continuous system operation.
Applications
This power module is essential for:
-
Industrial machinery condition monitoring systems using rack-based architecture
-
Environments requiring high reliability and power redundancy (e.g., turbines, compressors)
-
Installations in industrial plants such as power generation, oil & gas, chemical processing, and more
-
Scenarios where minimal modules should be powered even during maintenance periods
Advantages
-
High-voltage input with broad range supports global AC power standards
-
Redundancy-capable design ensures uninterrupted rack operation
-
Compact and lightweight for efficient rack integration
-
Rugged temperature and humidity tolerance for reliability in harsh environments
-
High efficiency (~90%) keeps power waste low and heat output minimal
-
Ease of maintenance via hot-swap capability when paired with a backup supply
