Acceed's SuperCap UPS: 10-Year Service Life for Controllers & Box PCs

Power interruptions have long been mitigated with battery‑based UPS systems. Super capacitors, or SuperCaps, now offer a superior, longer‑lasting alternative. Acceed delivers two models engineered for controllers and Box PCs.

Industrial environments routinely face sudden power failures—from emergency shutdowns and machine damage to grid overloads. While UPS devices are standard for short‑term protection, their primary goal is to enable a controlled shutdown of controllers, preserving critical data such as switch status, positions, and safety conditions. A brief outage can erase this information, causing extended downtime—especially problematic for data centers.

Traditional UPS systems rely on lead‑acid batteries. Although they scale quickly and are modular, batteries have significant drawbacks: narrow optimal temperature ranges, self‑discharge, the need for regular charging, and hazardous gas generation during charge cycles. Their lifespan is typically around five years, making them labor‑intensive and costly.

SuperCap UPS solutions overcome these limitations. Super capacitors are low‑maintenance, temperature‑resistant, and boast a proven 10‑year service life. They reduce operating costs, improve energy efficiency, and are more environmentally friendly than lead‑acid batteries.

Acceed’s German‑based PB‑9250J‑SA and PB‑2500J models are fully service‑free and designed for high reliability. The PB‑9250J‑SA is a compact, stand‑alone unit built around eight 370 F/3.0 V capacitors, delivering 9,250 Ws of storage. Its patented Neousys energy‑management technology guarantees a steady 18 W output and seamless auto‑on/off transitions without additional drivers or software. Beyond UPS mode, the unit supports two ignition‑control functions, making it ideal for vehicle controllers that demand precise behavior during ignition cycles.
