PQ-GUARD
The next-generation solution to your company's voltage problems
By installing the PQ-GUARD device with supercapacitor technology, your business can eliminate 100% of micro-interruptions, voltage dips and swells. It ensures uninterrupted power supply by eliminating interruptions of up to 1 second at full power and for longer periods in the event of lower power consumption.
FAQ
Yes, even interruptions lasting longer than 10 ms can cause sensors and PLC to reset, bringing motors and the systems connected to them to a standstill.
The PQ-GUARD can eliminate voltage interruptions of up to one second at full power and for longer durations in the case of lower power consumption
Even when operating in Eco-Mode, i.e. in high-efficiency bypass mode, the response time is virtually instantaneous, around 2 ms; the system does not notice the power interruption.
These are two fundamentally different technologies: compared to a traditional UPS, the PQ-GUARD has drastically lower self-consumption (< 1% of rated power compared to the average 5% of a UPS), an infinitely longer service life (1 million cycles compared to an average of 5,000 for a UPS) and negligible maintenance costs compared to the high costs of lead-acid or lithium UPS systems, thanks to the absence of chemical reactions in the storage technology.
Why PQ-GUARD
-
EDLC supercapacitor technology
EDLC supercapacitor technology represents an advanced solution for voltage stabilisation in industrial systems. Thanks to their ability to store and release energy extremely rapidly, supercapacitors guarantee a virtually instantaneous response to grid events, making them particularly effective in managing micro-interruptions and voltage dips. Unlike traditional UPS systems, the system operates continuously in standby mode with extremely short response times and a lifespan of up to approximately 1 million operating cycles.
-
Low maintenance and long-lasting
The PQ-GUARD system, equipped with sophisticated electronics and EDLC supercapacitors, does not require the maintenance typically associated with lithium or lead-acid UPS systems, and its components maintain high performance even across a wide range of temperatures. Furthermore, operating only when actually needed reduces stress on components and energy consumption, enabling the system to achieve an extremely long service life.
-
Low sensitivity to temperature fluctuations
As the storage technology involves no chemical reactions the PQ-GUARD system operates within a wider temperature range than conventional UPS systems, making it particularly suitable even for the most challenging installations.

The supercapacitor technology behind PQ-GUARD: how it works
PQ-GUARD is an active voltage conditioner (AVC) that essentially in the grid power supply in real time. If a sudden voltage dip occurs, instantly injects the missing energy , filling the gap before the system even notices. Thanks to supercapacitor technology, PQ-GUARD operates in Eco Mode like a silent shield, intervening only when necessary to protect the system from voltage dips or surges with 99% energy efficiency. An EDLC supercapacitor is structurally composed of two porous electrodes with a very high specific surface area immersed in an electrolyte. Charging does not trigger chemical reactions: the electrolyte ions are physically adsorbed onto the surface of the electrodes, storing energy through the electric double layer. The process is primarily physical, highly reversible, and does not involve deep chemical reactions as occurs in batteries.
