APC SUA500PDR-S

Overview

The APC SUA500PDR-S is a DIN rail or panel mount uninterruptible power supply designed to keep critical equipment running smoothly during voltage fluctuations, surges, and unexpected power outages. With a capacity of 500 volt-amps (325 watts) and delivering a pure sine wave output at 120 volts, it ensures sensitive controllers, gateways, and instrumentation receive clean and stable power. Its compact design fits easily onto standard DIN rails or mounts directly to panels, making it ideal for environments where space is limited, such as control panels and production lines.

Key features

• Mounts on DIN rails or panels to optimize space in tight industrial setups
• Hot swappable lead acid battery allows for maintenance without interrupting power to connected devices
• Front panel LED indicators provide clear, real-time status of input, output, and battery health
• Up to 94 percent efficiency at full load reduces energy consumption and heat generation
• Automatic self-testing continuously monitors battery condition to alert you before replacement is needed
• 540 joule surge protection safeguards connected equipment from damaging power spikes
• RS-232 communication port enables easy integration with monitoring software and building management systems for remote oversight
• Temperature-compensated charging extends battery life by adjusting charging based on ambient conditions
• Pure sine wave output ensures compatibility and reliable operation of sensitive electronic devices

Connectivity and compatibility

This UPS is designed to integrate seamlessly into industrial and commercial control environments. The RS-232 port allows connection to monitoring software or building management systems, providing remote status updates and alerts. Its pure sine wave output supports a wide range of sensitive equipment including programmable logic controllers, sensors, and networking devices that require clean and stable power.

Installation and setup

The compact form factor and flexible mounting options make installation straightforward in confined spaces. It can be easily slid onto a standard DIN rail or securely bolted to a panel, fitting well within control cabinets or production line enclosures. The battery compartment is accessible from the front, enabling quick battery swaps without powering down connected equipment, which minimizes downtime during maintenance.

Ideal uses and environments

The SUA500PDR-S is well suited to industrial settings where reliable power is critical, such as manufacturing lines, water treatment plants, and building automation systems. It supports equipment that demands clean power and uninterrupted operation, making it a strong choice for engineers and technicians managing sensitive control and monitoring devices in space-constrained environments.

Returns are accepted within 30 days of delivery. Items must be unused, in the same condition received, with tags, manuals, accessories, and original, unaltered packaging. Any item kept will be deducted from the refund. Start a return by sending us an email. Items sent back without approval may be refused or returned to the sender.

Some items are not returnable: opened TVs/combos/monitors 37″+, opened computers or software, electronic downloads, opened consumables (film, paper, bulbs, media, ink), custom or modified computers, special-order or “nonreturnable” items, submerged underwater gear, and opened educational media.

After inspection, refunds are issued to the original payment method; allow 5–7 business days for the credit to post. Shipping, handling, customs duties, and import taxes are nonrefundable. If an item is used, incomplete, or not in original condition, a 30% restocking fee may apply. Direct exchanges are not offered; purchase the replacement and return the original for a refund.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
