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 surges. 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, particularly interruptions and dips lasting between 200 ms and 1 second can cause very serious damage, such as drive failure, damage to electronic circuit boards, and even total system shutdown and ICT system failure.
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 profoundly different technologies: compared to a traditional UPS, the PQ-GUARD has drastically lower self-consumption (< 1% of rated power versus at least 5% of a UPS), an infinitely longer service life (around 1 million cycles compared to 3,000 or 5,000 for a UPS), negligible maintenance costs compared to the high costs of a UPS and, finally, no risk of fire, unlike the lead-acid and, above all, lithium batteries used in UPS systems.
Why PQ-GUARD
-
Next-generation technology
This is an extremely efficient technology for resolving voltage issues in systems that cause malfunctions, breakdowns and machine downtime. Compared to traditional UPSs, supercapacitors allow energy to be released at an unrivalled speed. Furthermore, unlike to lithium batteries, they require no maintenance, withstand wide temperature ranges and last for decades.
-
High reliability and low maintenance costs
The inherent characteristics of EDLC supercapacitor technology allow the device to intervene in real time only when necessary to compensate for voltage fluctuations, thereby minimising component degradation and energy self-consumption and achieving approximately 1 million useful cycles.
-
No risk of fire and low sensitivity to temperature fluctuations
Compared to lithium and lead-acid batteries, supercapacitors are immune to the risks of fire and explosion and are practically insensitive to temperature fluctuations.

The supercapacitor technology behind PQ-GUARD: how it works
PQ-GUARD is an active voltage conditioner (AVC) that essentially ‘smooths out the ripples’ in the mains 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.
