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.

Schurter presents its new standard DC filter series FMER SOL suited for use on the DC side of the inverter in photovoltaic systems and other DC systems.

Modern solar inverters, that use MPP (maximum power point) trackers, generate disturbances into both the grid’s AC power line, as well as the DC side of the solar module. An AC filter is normally used on the grid’s AC power line, but the noise generated on the DC side tends to be overlooked.  EMC standards EN 61000-6-3 and EN55014-1, however, also put limits on the noise generated from lines not connected to the grid, such as for example the line to the solar panels. Meeting these limits can be achieved by using a DC filter on the DC side of the inverter.

Large solar inverters installed in electrical installations will generally require a cooling system. Components which provide high temperature resistance simplify the system and reduce the energy needed to cool. The FMER SOL filters are designed for rated currents from 25A to 1500A at 55°C ambient temperature, and voltages up to 1200VDC.  The filters are cURus and ENEC approved up to 75°C ambient temperature, with corresponding reduced rated currents.

The FMER SOL DC filters are designed with screw clamps for types up to 150A and copper bars for types upwards of 250A. Other types of connections, such as wires or copper bars <250A, are available on request.  Small adjustments can also be made to the electrical circuit or to the filter housing on request.

MICRO SWITCH™ BX2 Series Delivers Corrosion Resistance and Provides Both Cost and Time Savings to the End User

Honeywell’s MICRO SWITCH™ BX Hazardous Area Limit Switch Series now contains the MICRO SWITCH™ BX2 Series, complete with stainless steel, corrosion-resistant housing.

The MICRO SWITCH™ BX2 Series’ stainless steel housing provides enhanced corrosion resistance in applications exposed to aggressive, caustic agents often found in chemical processing plants, off-shore/near-shore sites, and other hazardous areas.

Honeywell Sensing and Control developed the stainless steel BX2 Series in response to significant customer demand. This new series can provide corrosion resistance up to four times longer than standard housing switches. It can also save up to four-weeks of down time when replacing rusty, unsafe switches.

Explosion-proof and weather sealed, MICRO SWITCH™ BX2 Series switches have global ATEX and IEC Ex approvals. These switches can withstand the pressure of an internal explosion and IP67 and NEMA (1, 3, 4, 6, 7, 9, 13) ratings ensure the BX2 can survive in outdoor operations for an extended period of time.

To meet customer requirements for design flexibility, the BX2 Series is available with a broad range of sizes, orientations, actuators, and electrical load options. Potential applications are many, including control valves and actuators, offshore drilling, gas recovery units, petrochemical plants, grain elevators, waste treatment, paint booths, mining conveyors, pulp and paper handling, and hazardous waste handling.

Finder has introduced a pair of solid state relays for silent, high-speed switching of single and 3-phase loads rated at up to 5A.  The 77 Series relays’ 300A peak current handling capability makes them particularly suitable for use with high inrush current loads, including electronic starters and igniters for fluorescent and gas discharge lamps.

Two 77 Series relay variants are available:  ‘zero-crossover’, minimising voltage and current stresses to improve reliability and greatly reduce EMI, and ‘instant switching’, ensuring a consistent time between relay input and output, of importance where simultaneous switching is desirable as in 3-phase switching.

The relays have a single AC output and can be specified with either AC or AC/DC control inputs for added flexibility.  5kV insulation between input and output assures a high level of application safety and security.  Provided in a compact 17.5mm wide housing for 35mm rail mounting, the 77 Series also features an LED operational status indicator and an integral heat sink.

The solid state relay’s spark- and bounce-free switching characteristics ensure a virtually infinite electrical life, of particular benefit in high-speed, repetitive applications and in domestic and office environments, where electrical interference needs to be kept to the absolute minimum.
