Passive harmonic filters are an excellent tool for improving the compatibility of motor drives with the public power grid. Schaffner extends the popular ECOsine™ product range with filters for 690V systems, supporting a straightforward upgrade from standard motor drives to «low harmonic drives».
With the extension of the ECOsine™ product family, Schaffner, the international leader in the fields of electromagnetic compatibility and power quality, is raising the bar for harmonic mitigation solutions anew. The new passive 690V harmonic filters are an ideal solution for 3-phase equipment with 6-pulse front-end rectifiers, like e.g. variable speed drives or battery chargers.
Frequency inverters for energy efficiency and speed control of electric motors can, in combination with ECOsine™ filters, be utilized as low harmonic drives, causing minimum system perturbation. As a result of the significant reduction in total harmonic current distortion (THID) to typically 5%, ECOsine™ filters can uniquely guarantee compliance with the toughest requirements of IEEE-519 and other stringent international power quality standards. Drive and filter combined allow for unconditional use without the need for a costly power quality analysis in each case. The electrical infrastructure is reliably unburdened, transformers are utilized much more effectively, and the failure rate of neighboring electrical consumers is reduced.
The new ECOsine™ filters FN341xHV are rated for 690VAC/50Hz grids like those often used in chemical plants, in oil and gas exploration, or in heavy industry. The filters are available as a standard for diode rectifiers (FN3410HV) and upon request for thyristor rectifiers (FN3411HV). They come in common steps of power rating from 7.5 to 250kW. The compact filters are designed with IP20 rated enclosures, suitable for cabinet integration or for wall mounting in electrical utility rooms.

Barely one year after the introduction of ECOsine™ passive harmonic filters, Schaffner presents the digital solution for the efficient reduction of system perturbations: ECOsine™ Active. Latest generation electronics enable an intelligent and adaptive compensation of harmonic currents with a response time of less than 300 microseconds.
The use of ECOsine™ Active supports the owner in complying with the stringent international harmonics standards as well as with local utility codes. At the same time the electrical infrastructure is unburdened, a potential overheating of transformers, motors, cables etc. is prevented, and the pre-mature wear of electrical equipment is reduced. The improved Power Quality minimizes the risk of downtimes and process interruptions, saves energy and money.
Besides the global or selective mitigation of harmonic currents up to the 50th order ECOsine™ Active is able to perform power factor correction in a targeted manner. In highly dynamic processes like they are found in welding robots, for example, ECOsine™ Active provides the required reactive power within microseconds, faster than traditional automatic cap banks.
ECOsine™ Active is easy to install and intuitive to operate. The compact package of ECOsine™ Active makes its use possible even when space is at a premium. The 50 and 100 Amp filters in IP20 design are ideal for panel integration, so they can, for example, be installed right by the non-linear load. The IP54 rating of the 300A unit provides protection against dust and environmental influences, perfect for harsh industrial applications.
ECOsine™ Active is available in 3-phase/3-wire as well as 3-phase/4-wire configuration for 480V and 400V grids respectively and with rated compensation currents of 30 to 300A. All 3-wire filters are UL listed and therefore ready for the North American market. Building technology and HVAC installations, heavy industry, data and banking centers, UPSs, water/wastewater treatment facilities, or welding equipment can equally benefit from the many advantages of ECOsine™ Active.

UP1 Undervoltage Release Switch for Operators Safety
The new UP1 undervoltage switch monitors the supply voltage and actuates a trip release when there is an intense drop in voltage or when the supply voltage is interrupted. As soon as the supply voltage returns in full, the machine or equipment does not automatically restart in an uncontrolled manner, but must be consciously switched on again. Using this function, dangerous situations for operating personnel as well as for the surroundings of the device itself can be prevented.
The UP1 is a 2-pole circuit breaker with additional undervoltage monitoring actuates a trip re-lease with a loss of voltage or an intense voltage drop. The breaker is available with rocker actuation for snap-in mounting or with push-button actuation for both snap-in mounting as well as screw fitting. Protection covers against the ingress of dust and spray water make the use of the breaker in harsh environments such as wood-, masonry- or metal-workings possible.
The requirement for the use of undervoltage protection is in existence for applications such as gardening equipment, gardening shredders, floor cleaning and sanding devices, electrical tools such as circular saws, band saws, grinding machines and drills. Further examples are fuel pumps, coffee-milling devices, fruit juice squeezing machines and fruit juice centrifuges.
The UP1 undervoltage circuit breaker is configured differently in its hardware for various net-work supply voltages und must be therefore ordered for the appropriate supply voltage. Rated switching category is AC-1 16A / AC-3 14.5A @ AC 240 V. The breakers are approved to IEC 60947, UL 508, CSA 22.2 No.14-95 and also contain a horsepower rating.
Technical Characteristics:
- 2-pole switch
- Undervoltage trip release with restart prevention
- Available with rocker or push-button actuation
- Dust and jetting water protection to IP 65
- VDE & cURus approvals for rated currents AC-1 16A / AC-3 14.5A @ AC 240V

V-Lock Cord Retaining System
This V-Lock system by Schurter is an attractive and simple solution to prevent an unintentional unplugging. Various different connectors, Power Entry Modules and several country-specific power cables are available with this option.
.
The V-Lock locking system can be used for 10A and 16A power inlets and connectors according to IEC 60320. This system works in such a way that there is a pin in the socket, interlocking with a notch in the plug and thus prevents an unintentional pullout of the power cable. The advantage of this system is that there is no need for a specific socket system or retaining device that has to be adapted and built-in.
The locking is released by pressing on the releasing lever. This lever is easily detected by its bright yellow colour and thus distinguishes this system from existing power cable connections. The extraction force is a minimum of 200 N. Typical applications are in medical appliances,
analysis and laboratory instruments, Telecom and IT- devices, power distribution or radio and TV-studios.
.
USP's: - prevents unintentional disconnection
- increased safety and reliablility
- most cost effective cord retaining solution on market
- attractive design
- easy to use
The following connector types can be manufactured with the V-Lock option in series:
6010, 6061, GSP1, GSP2, DF11, 6600-3, 6600-4, 6610, 4797

Finder has announced additions to its 18 Series of PIR motion detectors supporting a variety of interior energy saving schemes. The compact 18.21 and 18.31 variants will meet the needs of higher ceiling, higher load switching applications and those requiring direct interface to a PLC or BMS.
Recess mounted, the flush fitting 18.31 suits suspended or plasterboard ceilings while the 18.21 is a low profile PIR for hard surface mounting. Providing a 10 amp rated normally open volt free output, the detectors will switch loads at any voltage and are not restricted to 230VAC mains tasks. 24V ac/dc supply versions are also available for applications without a mains supply or where safe, low voltage operation is required.
With a 110º wide sensing angle and a reach of 2.8m, the 18.21-0300 and 18.31-0300 PIRs will handle all types of regular ceiling height applications. For high bay or extended ceiling height duties, the 18.31-0031 PIR variant offers a much longer sensing range of up to 8m.
The Finder PIRs also offer an adjustable light threshold setting allowing operation to be varied according to ambient light conditions. In addition, an enhanced light-on time adjustment of up to 35 minutes makes the PIRs well suited to HID lamp applications, which for reasons of preserving lamp life, place a restriction on the number of starts per hour.
