Cabinet Helps Alleviate Temperature Concerns When Installing Control Panels
STI’s new STI-7550AH protective cabinet allows a fire alarm control panel to be mounted in temperatures exceeding normal parameters. The extra large, tough, see-through polycarbonate enclosure offers protection against vandalism as well as dirt, dust and grime.
The AC/heater unit allows sensitive devices to be installed in areas suffering from damaging conditions, such as outside of factories and warehouses or locations that are dirty or experience high humidity. The enclosure can also eliminate the expense of air conditioning or heating an entire warehouse or an unmanned warehouse.
To help sustain a uniform temperature inside the enclosure, the AC/heating unit cycles as required and a fan runs continuously. The AC/heater contains an integral power supply and built-in condensate removal system. The unit does not require a compressor, fluorocarbons or filters.
The STI-7550AH is self-contained and allows for optimal central location of the control panel. This will reduce expensive long wiring runs from an inefficiently placed control panels and eliminate the need to wire to an isolated storage room. Installers will save on equipment, wiring costs and even the horror of constructing a special room specifically for the unit.
New Shielding Technology for Space Constrained Applications
As circuit board footprints decrease and chip speeds continue to increase, efficient board layout and proper EMI shielding become major engineering concerns. Several factors including shield space, weight and cost are under ever increasing scrutiny. To satisfy these demands, Leader Tech now offers a multi-cavity version of its standard CBS product line.
The company’s multi-cavity CBS products effectively combine multiple circuit board shields under the same footprint reducing space, weight, assembly cost and time-to-market. Leader Tech’s multi-cavity CBS products use standardized manufacturing methods to create shielding solutions with minimal nonrecurring engineering charges (NRE) and virtually limitless customization options.
New Circular Wire Rope Isolators from AAC Feature a Low Profile for Compact Military and Industrial Applications
The new series of 18 compact, low profile circular wire rope isolators from Advanced Antivibration Components (AAC) feature multiaxial shock and vibration protection, corrosion-resistance and maintenance-free operation. The cable itself is made from stainless steel and the mounting plates are made of aluminum. These mounts, identified as V10Z69 series is stocked in 1/16, 3/32, 1/8, 3/16 and ¼ inch diameter cable.
New CE Compliant Cabinet Coolers For Electrical Enclosures
EXAIR’s CE compliant Cabinet Coolers are a new low cost way to purge and cool electrical control panels. The cold air is circulated through the enclosure to eliminate heat damage and control shutdown. Independent laboratory testing certifies that Cabinet Coolers meet the appropriate CE safety requirements that now make them suitable for a wide range of enclosure cooling applications.
The compact Cabinet Coolers can be installed in minutes through a standard electrical knockout hole. They convert an ordinary supply of compressed air to cold, 20°F air without refrigerants or CFC’s. Cabinet Cooler Systems include a compressed air filter to assure no moisture or dust is introduced inside the panel. Optional thermostat control minimizes compressed air use. Cooling capacities up to 5,600 Btu/hr. are available. Cabinet Coolers are UL Listed and maintain the NEMA 12, 4, and 4X rating of the electrical enclosure. There are no moving parts to wear out and no maintenance is required.
New Circuit Breakers Keep Systems Running
Phoenix Contact has introduced a new range of circuit breakers that combine the advantages of fuse terminal blocks with the benefits of thermal-magnetic circuit breakers. The UT 6-TMC M series is a resettable, single-pole circuit breaker with screw connection.
Tripped circuit breakers on the TMC are clearly indicated and can be easily reset with the press of a button. The series is available in 11 graded steps for nominal currents from 0.5 to 16 A. Two bridge shafts simplify distribution.
Measuring 12.3 mm wide, the UT 6-TMC M circuit breakers occupy 30 percent less space than conventional 17.5 mm circuit breakers. The series is part of Phoenix Contact’s ClipLine Complete system, which features standardized push-in bridging, marking and testing accessories for all connection technologies. |
