The SITOP UPS501S is a maintenance-free capacitor expansion module that extends the buffer time of SITOP UPS500S uninterruptible power supply systems. Each module provides 5 kWs of additional energy storage using double-layer capacitor technology, enabling scalable protection for industrial automation loads.

Scalable Buffer Extension

Up to three UPS501S expansion modules can be connected in parallel to a single UPS500S base unit, allowing engineers to scale backup duration precisely to application needs. The maintenance-free capacitors require no ventilation of the control cabinet.

Technical Specifications

Application

Designed for extending the backup time of UPS500S base units in automation cells, machine tools, and process control systems where controlled shutdown is critical for data integrity.
