SUA500PDRI-S APC 500VA Line-Interactive UPS/USV

Industrial DIN-Rail Line-Interactive UPS for OT panels and hardwire distribution with the SUA500PDRI-S

The SUA500PDRI-S is an APC Smart-UPS engineered for industrial control enclosures where stable single-phase power and predictable shutdown behavior are required. By combining line-interactive regulation with hardwire 3-wire input and output, the SUA500PDRI-S supports panel builders and OT engineers who need a compact DIN-rail UPS that integrates cleanly into PLC/SCADA cabinets and field housings.

Architecturally, the SUA500PDRI-S focuses on voltage conditioning and short-runtime backup rather than long-duration energy storage, aligning to brownout handling and ride-through for sensitive controllers, gateways, and managed switches. With 500VA / 325W capacity and efficiency performance class VI, it is sized for edge control loads while limiting heat within sealed cabinets. The line-interactive topology provides regulated output during input variance, and the hardwire I/O model reduces connector failure points, improves strain relief, and supports code-aligned panel wiring practices in distributed OT deployments.

Why Choose the SUA500PDRI-S?

The SUA500PDRI-S delivers a high density-to-function ratio for DIN-rail environments by combining regulation, surge protection, and managed backup in a single UPS footprint. For scale-out sites, the SUA500PDRI-S enables repeatable cabinet designs, predictable autonomy planning (vendor-stated 24 minutes at 50% load), and consistent behavior across multiple remote enclosures, improving operational reliability and simplifying standardization.

APC designs Smart-UPS platforms around controlled power delivery, robust protection stages, and lifecycle-oriented reliability expectations for enterprise and industrial installations, with compliance alignment to UL, UL 1449, RoHS, and REACH to support modern data centre and OT safety requirements.

Key Applications:

• PLC and SCADA control panels
• Industrial network switches and edge gateways
• Remote I/O cabinets and field enclosures
• Brownout mitigation and voltage regulation
