Crouzet Timers

crouzet1

A timer is a simple automation component which is used to manage actions over a period of time or control how long actions last.  The timer is a control device which triggers an action according to a time and a function.  After a predefined time has elapsed, the timer closes or opens one or more contacts. Timing cycles, whether single shot or repetitive, are started by latching inputs or pulsed inputs, allowing a wide variety of functions to be created.

Timers can be found in electrical cabinets associated with other automation functions for the following markets:

• Food industry
• Industrial automation systems
• Lighting
• Building equipment
• HVAC
• Small or large industrial machines

Schurter AEO 10.3×38 Fuse

Schurter Logo1.jpg

High Performance Fuse For Automotive Applications
• Very high rated current up to 50 A
• Safely interrupting 1000 VDC
• Versatile mounting options

With the AEO 10.3×38, SCHURTER launches a high-performance fuse for particularly high voltages up to 1000 VDC and currents up to 50 A, which is particularly suitable for automotive applications.

High voltages and high currents occur in electric vehicles in numerous places. Their battery packs with several thousand rechargeable cells store enormous amounts of energy. This in order to meet customer requirements concerning driving performance and range by still providing the shortest possible recharging times. To safeguard this level of power, you need highly reliable high power fuses. Such fuses are required, for example, in the BMS (Battery Management System), for on-board and off-board chargers, DC-DC converters and other systems exposed to high voltages.

Welding Is More Reliable
A weak point of every fuse is the connection between the melting wire and the contact cap. This connection is usually done by a solder joint. In the fuse production process, however, this technology brings quite many difficulties. Creating the connection by welding increases the reliability by far. SCHURTER uses a new, patented process which guarantees highest reliability.

Versatile Mounting Options
The new fuses of the AEO series offer a multitude of possible mounting options. In addition to the cartridge fuse, which requires a fuse clip (recommended model: SCHURTER CSO) and the classic mounting directly on a printed circuit board, screwable version for surface mounting or even axial mounting are available.

Applications Automotive:
DC/DC Converter, On Board Charger, Battery Management System, PTC-Heater and Houshold Charging Stations.

Schurter NEMA Receptacles 5-15R

Schurter Logo1.jpg

Convenience Outlets Redesigned
• NR010 – IDC for efficient wiring
• NR020 – The classic with improved temperature rating
• NR021 – Tamper Resistant

Schurter’s latest series of appliance outlets NR020 and NR021 combine classic features with new ones to meet increased fire protection and safety standards according to UL 498 Tamper Resistant, as well as facilitating compliance of receptacles used in Household and Commercial Furniture and Furniture Power Distribution Units (FPDUs), according to UL 962 and UL 962A. Higher temperature ratings and added configurations for series NR010 and NR020 respond to power demands facing Datacom infrastructures today.

Tamper Resistant Receptacles – TRR The concept of tamper-resistant receptacles is not a recent development; these devices have been a standard product offering of wiring device manufacturers for many years. The devices are designed to protect individuals (primarily children) from accidental shock resulting from the insertion of foreign objects. The US National Electric Code NEC® Article 406.12 states that all 15- and 20-ampere, 125- and 250-Volt nonlocking-type receptacles installed in dwelling units must be Tamper Resistant. In 2017, changes to the Code expanded on these requirements and locations. Previously, tamper-resistant receptacles were required in dwelling units, guest rooms and guest suites of hotels and motels, and in child care facilities. The expanded code brings these safety devices to preschools and elementary education facilities; business offices, corridors, waiting rooms and the like in clinics, medical and dental offices and outpatient facilities; to assembly occupancies such as places of awaiting transportation, gymnasiums, skating rinks, auditoriums; and to dormitories. These expanded locations are areas that small children frequently occupy.

Tamper resistant receptacles feature a UL recognized safety shutter system that prevents the insertion of foreign objects into a receptacle. The safety shutters will only open upon simultaneous insertion of two plug blades. Additional tests including Probe Test, Impact Test, Mechanical Endurance Test and Dielectric Voltage Withstand Test for Tamper Resistant Receptacles TRR are included in UL 498. After passing all the above performance tests, tamper-resistant receptacles must have either the words “Tamper Resistant” or the letters “TR” (minimum 3/16 inches high) on the device as a clear indication that this is a tamper-resistant receptacle.

Schurter’s NR021 NEMA 5-15R Tamper Resistant series meets the expanded code requirements according to UL 498. Additionally, with the option of an added insulated wall between the L, N terminals, compliance with the Spill Test, outlined in UL 962 Sec. 62, is more cost effective and efficient for manufacturers of Household and Commercial Furniture and Furniture Power Distribution Units (FPDUs).

Higher Temperature Rated Receptacles Packing density of equipment for data communication and storage continues to be regularly revolutionized with the surge of usage and functionality. Increasing ambient temperatures go hand in hand with these advancements, as demand trickles down to the smallest components to keep pace with emerging needs of the appliance manufacturers. The NR010 and NR020 series have an operating temperature range of -25 ˚C to 150 ˚C in response to the power needs of the Datacom industry. In addition, the NR010 with IDC terminals provides a version with an independent L terminal. The neutral and ground terminals can still be bussed, while the line terminal can be used for maximum load according to UL rating 15 A, 125 V. It also extends the capability of adding functionality to each outlet individually.

Crouzet Launches New Compact Power Supplies

crouzet1

Crouzet, global supplier of electronic and electromechanics components, has recently released a new line of compact power supplies that offer greater efficiency in a smaller size. The new range of power supplies feature simplified wiring and are perfectly adapted to fit existing Crouzet products.

Each power supply in Crouzet’s new range is 18 mm (1module) thinner than its predecessor. This efficient use of space allows industries to save valuable space. Miniaturization of products is an important trend in the industrial world, with many businesses looking to cut down on the amount of space that their products take up. There are several options in the new Crouzet range with power values of 10 W, 30 W, and 60 W. For the first time, Crouzet has added a new 100 W power supply to its compact line. Crouzet’s power supplies feature simplified wiring, which makes setting up power supplies easier and more straightforward than ever before.

Efficient Operation of New Power Supplies Saves Energy
The new generation of compact power supplies offers improvements in efficiency of up to 90%. They can operate at an increased temperature range of -20 °C to +70 °C. These DIN Rail mount power supplies are therefore suitable for use in a wide range of energy-intensive situations, including HVAC, greenhouse environments, and hydraulic solar heating. They all offer improved performance compared to older models of power supplies.

As well as being energy efficient, Crouzet’s new power supplies are also incredibly safe. They have double insulation and a safety Class II input, which means that no connection to earth is required. This combination of efficiency, performance and safety makes the new power supplies the ideal choice for many industry applications, including renewable energy, access control, compact industrial machines, and building equipment.

Standalone Power Supplies Offer Compatibility With Many Crouzet Products
Power supplies are no longer simply accessories for Crouzet logic controllers. They now exist as standalone products, with their own features and benefits that can offer significant advantages to businesses. All logical controllers and control products need a reliable power supply to function, and the new Crouzet supplies are an excellent choice. The new power supplies are compatible with Crouzet 24 VDC products including HMI, nano-PLCs, tele-controllers, timers, logic controllers, and many more products.
