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 […]
UPS for an Network Video Recorder (NVR) Clearly in security applications and where recording may be the only evidence of a crime, continuity of power is essential. A security guard may spot somebody on CCTV and raise an alarm, but the evidence is the recording itself. An Uninterruptible Power Supply (UPS) provides the continuity of […]
Why use a UPS on a Pharmacy Fridge? Unlike applications where sudden power loss causes data loss or other operational issues, power loss to a pharmacy fridge is not such of an issue since the internal temperature is well controlled. In the event of a power cut a solution is simply not to open the […]
We’ve made some changes to our website. This is to more reflect the type of business that Power Inspired has evolved into, whilst maintaining the link to what got us here in the first place. We were the first company to open an online store exclusively for power protection products. Previously, you would have had […]
The iPower is an ideal solution to enable the continuity of telephony services in the event of a power outage for GPON ONT devices.
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.
Power Inspired’s VFI6000BL, provides 5400W of power capability with a 6A charger on up to a 240V battery string for fast recharge of large battery banks
We’ve made some changes to the AG fan speed adjustment control. It’s now a simple push button instead of a POT adjustor or the spindle.
Lead Acid Batteries are the ubiquitous form of energy storage for Uninterruptible Power Supplies due to the high power density that can be achieved, simple charge characteristics and non-spillable operation. In pluggable UPS systems the lead acid batteries are always maintenance free and sealed, e.g. they do not require topping up with distilled water. They […]
