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.

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 capacitors require no ventilation of the mounting location per VDE 0510 Part 2 and EN 50272-2.

Technical Specifications

Application

Ideal for industrial automation environments where the base UPS500S buffer time must be extended to ensure safe shutdown of PCs, controllers, and data logging systems during power interruptions.
