Finder has introduced surge protection devices (SPD) designed specifically for photovoltaic (PV) panel installations.  Additions to its popular 7P Series of SPDs, three new Type 2 surge arresters will protect PV systems from the effects of lightning strike and electrical switching transients.  The products are already supporting the company’s own PV panels at its primary manufacturing plant.

Featuring encapsulated spark gap and/or replaceable varistor modules, the three devices protect the more vulnerable DC side of commonly used earth free and mid point earthed PV systems.  The range includes: the 7P.26.9.420, providing 2 varistors and 1 spark gap for 420V DC systems; the 7P.23.9.700, providing 3 varistors for 700V DC systems and the 7P.23.9.000, providing 3 varistors for 1000V DC systems.

Each device integrates both a visual indicator and a signalling contact to warn when a varistor module needs replacing.  Connection to the signalling contact is via a convenient plug-in terminal block.  The SPDs comply with EN 61643-11 standard and can be 35mm rail (EN 60715) mounted.

Finder’s introduction of a range of SPDs tailored to the needs of PV installations comes at a time when UK government Feed-In Tariffs (FITs) appear to have stimulated a step increase in interest in PV system in the country.  The UK is now the fastest growing market for PV solar energy installations, estimated to produce 96MW of electricity in 2010 compared with 6MW in 2009.

At the same time, a prospective revision of the UK wiring regulations, placing far more emphasis on the provision of protection from electrical surges, has meant there is a resurgence of interest in associated products, in particular varistor and spark gap type SPDs.

PV panels at Finder’s prime manufacturing site in Almese near Turin in North West Italy have been producing an output power of 55kW since early 2009, equating to 61,000 kWh/year.  So pleased with the performance, the company has this month commissioned a further 60kW of PV panels, which of course will be protected by the new 7P Series surge arresters.

Constructed using multicrystalline silicon PV modules, Finder’s initial PV system is calculated to have reduced CO2 emissions by about 37 tons/year, achieving annual cost savings of around 11 TOE (tonnes of oil equivalent).

With its latest ranges of compact yet versatile timing relays, Moeller Electric now offers convenient and cost-effective timer options covering virtually every control panel and power distribution application.

Special features of the Moeller Electric timer family include models for operation direct from 400V supplies, which are ideal for use in three-phase systems where no neutral is available, models with remote adjustment facilities, and ultra-compact versions just 17.5mm wide, which save valuable space in distribution boards.

Featuring the same design and dimensions as the popular DILEM contactors, DILET timers are well suited for control panel applications. They are available in three types, the DILET 11-30 which is an economical option where an on delay of between 1.5 and 30s is required; the DILET 11-M which also offers an on-delay function, but has ten timing ranges covering 0.5 seconds to 60 hours; and the DILET 70 multi-function relay which offers a choice of eight timing functions as well as the option of adjusting the setting with a remote potentiometer.

DILET timers can be supplied in universal versions for use with AC and DC supplies anywhere in the range 24V to 240V, and for 400V AC operation.

For applications where maximum versatility is required from a compact timing relay, Moeller Electric offers the ETR4 range. Just 22.5mm wide, these DIN-rail mounting units cover times of 0.05s to 100h in ten ranges, and offer a choice of different timing functions. The range offers a basic on-delayed timer, a star-delta timing relay and two multi-function relays, ETR4-69 and ETR4-70 offering eight timing functions. The ETR4-69 has a single changeover output contact, while the ETR4-70 has two changeover contacts and also allows the connection of a potentiometer for remote adjustment.

Both the ETR4-69 and ETR4-70 have an opto-isolated input to allow timing to be initiated from almost any kind of external circuit, and both incorporate LEDs that give a clear indication of current status.

Moeller Electric’s ultra-compact ETR2 timing relays have been specifically designed for use in distribution boards, and are the same size as most miniature circuit breakers. In spite of their small dimensions, they offer a timing range from 0.05s to 100h, and are available in six different versions, including a multi-function model. All ETR2 relays are suitable for use with AC and DC supplies in the range 24V to 240V.
