Given the high levels of integration in electronic systems, the demand for electrical components for use in higher temperature environments is continually increasing. This is where the new C22F appliance inlet and filter fills a gap. The first product of its type on the market performs exceptionally well in applications with higher ambient temperatures.

The new C22F filter series combines an IEC C22 high temperature appliance connector with a high quality power-line filter. The combined inlet and filter are especially suited for use in applications with nominal currents up to 16A at 75°C ambient and 20A at 65°C ambient. The unique design provides higher temperature ratings over comparable filtered inlets, while maintaining a similar compact size.

The combination power entry module integrates the EMC filter directly at the line input, providing an optimal effect on electromagnetic compatibility. The broad metal flange features a large amount of contact area, which further optimizes filtering and shielding effects. Wiring is done using quick-connect or solder terminals.

The standard C20F and new C22F series are designed for operating currents up to 16A at 250 VAC according to IEC standards and 20A at 125/250 VAC according to UL standards. They are ENEC and cURus approved. The two series are available in standard and medical versions suitable for applications according to IEC 60950, and medical applications according to IEC 60601-1. Such applications include power distribution units, servers, medical heating appliances and imaging systems.

- For high ambient temperatures
- Nominal current: up to 16A (ENEC/UL/CSA) at 75°C and 20A (UL/CSA) at 65°C ambient temperatures
- Version available with extra large X capacitor of 330 nF
- Filters available in standard and medical versions

Hylec-APL has introduced a new comprehensive range of Steatite ceramic terminal blocks which are ideal for wire termination in demanding high temperature applications.

The Steatite ceramic terminal blocks have several characteristics which make them advantageous over existing porcelain ceramic products. These include higher density, better bending/compression strength, greater elasticity, higher dielectric strength and being non-flammable and temperature resistant with dimensional stability up to 1,000˚C.

*  The terminal blocks are suitable for use in applications with continuous temperatures of up to 350˚C.
*  Range is available with two or three poles and in a choice of sizes.
*  Steatite terminal blocks include screw mounting holes which are M3, M3.5 or M4 in size.
*  Steatite, or soapstone, can be easily shaped and its electrical characteristics make it ideal as an insulator or housing for electrical components.
*  The range complements Hylec’s existing line of polyamide and polypropylene products.

Finder’s 77 Series “single pole” solid state relays are now available in eight new versions, with a 30A current rating to complement the existing 5A models.

With distinct models for zero-voltage and instantaneous switch-on, the former is particularly suited for lighting control where zero-voltage switching can significantly reduce high inrush currents. Instantaneous switch-on provides near instant switching for high speed operation and simultaneous switching in multi-phase circuits, such as three phase motors.

The very high inrush current capability of 520A (10ms) ensures reliability over a long life in a wide range of applications, particularly the switching of lighting where power factor compensation and electronic ballasts have historically been problematic – but it is also ideal for the control of heating, solenoids and motors.

In 22.5mm housing incorporating the heat sink and designed for 35mm rail mounting, the relays are ideal for use in control panels and cabinets in industrial and commercial applications.

Capable of switching single phase motors up to 2.5kW or lamp loads up to 6000W, and with the benefit of silent, high speed switching, they lend themselves to use in a host of environments. Input voltages of 230Vac and 24Vdc.
