PCB UPSU is a compact PCB-mounted UPS from inventlab GmbH, advertised as 100% Swiss Made and using Supercapacitors / Ultracapacitors as its energy storage medium. It is designed for short-duration backup power needs in electronic hardware: when the main power supply fails, it gives a device time to send an alert, save data, or perform necessary adjustment and switching actions.
According to the specifications, the module measures 35.56 x 22.86 mm, supports an input voltage of 3.3-5.5V, and offers a configurable output voltage of 1.2-5.5V. Its output controller is a Buck-Boost converter, meaning the input voltage can be lower than, equal to, or higher than the output voltageβuseful for 3.3V/5V embedded systems. The output current is listed as 0.6A / 1.2A derating, with a capacity of around 17J and expandable capacity. The operating temperature range is -40Β°C to +65Β°C, and the cycle life is rated at 500,000 cycles. Overall, it is positioned more as a power-loss hold-up and brief backup power module than as a long-runtime power source.
The page only describes it as a low-cost product and does not disclose unit pricing, volume tiers, MOQ, lead time, or payment methods. The purchase entry points to more Supercapacitor UPS solutions, but the main text provides no further transaction details, so buyers still need to contact the manufacturer or distribution channels before procurement.
The advantages are PCB-friendly integration, a compact footprint, high cycle life thanks to the supercapacitor design, and greater voltage-matching flexibility from the Buck-Boost architecture. Expandable capacity also makes it easier to select a configuration based on the systemβs required power-loss hold-up time. The drawbacks are that the public webpage is closer to a product brief: it lacks complete application circuits, certifications, reliability testing, BOM cost details, and a detailed selection guide. There is also no visible API, SDK, or software ecosystem information, which indicates that this is primarily a hardware power module rather than a software development tool.
It is suitable for teams building embedded hardware, industrial control systems, communications equipment, medical devices, security products, digital signage, and other devices that require power-failure protection. It is especially relevant for scenarios where only a few seconds to a short period are needed to complete critical actions. The page does not state the situation for access, payment, or delivery in mainland China, so china_access can only be considered unknown. Alternatives include other supercapacitor UPS modules, lithium-battery backup modules, industrial DIN-Rail UPS units, or custom power hold-up circuits.
