What a great question received into technical support today: Can you show the difference between the input and output voltage waveforms on the AC ReGenerator? We have a bit of bespoke in-house test equipment that we use for looking at the quality of the mains supply. It allows us to view both normal and common […]
“What is transfer time in UPS?” The definition of transfer time, sometimes also called switchover time, says it is the amount of time a UPS will take to switch from utility to battery supply during a mains failure, or from battery to mains when normal power is restored.

In telecommunication systems it is common to have a supply voltage of -48Vdc. What this means is that the positive terminal is grounded. But why 48V and why ground the positive end? Surely it would be more intuitive to ground the negative end? I’ll answer these questions in turn. Why 48Vdc? This is a trade […]
Power Problems Electricity is mainly generated by turning a large magnet through coils of wire. This induces a clean sinusoidal waveform that can be transmitted down cables, stepped up and down using transformers, to eventually find it’s way into our homes, offices and factories. Along the way, however, some power viruses can interfere with this […]
With the upcoming launch of the Power Inspired TX Series. We look at the isolation transformer, when we may need to use it and how we should use this properly.
What to do when you have no power, no electricity and you have a power outage. A guide to cope when there’s no electricity at work or at home. Simple FAQs and steps you can take to get through a power cut.
A new post better answering this topic has been created. Please see UPS Runtime Calculator. Well, we’re here again to answer the question of how long will a UPS actually last in the event of a power cut, but first, let’s clear up one of the biggest misconceptions… Runtime has nothing to do with the […]
