The PF-1e is a simplified, economical version of the PF-1 MK2 power strip. Keeping a similar architecture of the main filter allowed for the same level of protection to the connected devices, while savings in used components lowered its price significantly. Nevertheless the PF-1e is a brilliant device, which will prove itself in each – even very advanced audio-video system.
Designing the PF-1e we resigned from the most expensive components. This does not mean, that we used lower quality items or lowered the level of guaranteed safety. The architecture of the main anti-interference filter and the overvoltage protection remained unchanged compared to the PF-1 MK2 strip. Interference is blocked by a RLC filter block. It was built around high quality metalized polyester capacitors with low inductance and an IP (Iron Powder) filtering core. All elements of the filter are mounted using silver solder on a massive PCB with large cross-section traces.
In the power strip we resigned from using traditional protective elements like cartridge or thermal fuses, which have a detrimental influence on the sound as they throttle the current flowing to the protected device. The overvoltage protection of the power strip is based on a cascade of protective elements like plasma spark gaps and new generation of UltraMOV varistors. Working together with a properly made in-wall electrical grid, this setup guarantees a complete protection against overvoltage and overcurrent.
The massive chassis of the power strip is made completely out of metal. It constitutes also a perfectly sealed shield protecting from RFI and EMI interference. In the PF-1e we resigned from the signal LED and the distribution rails. The internal cabling is made from copper conductors with 2.5 QMM diameter. There are six Schuko output sockets. The PF-1e is also available with NEMA 5-20R sockets, used in United States and some Asian countries, as well as Australian type sockets AS/NZS 3112.
The PF-1e has an IEC input socket, which accepts all kinds of power cords. The strip is available in two versions: without cable and with a 1.5m power cord. To maximize the potential of the PF-1e we recommend the usage of the power cable LC-1 MK3 or LC-2 MK3
