Panasonic's new latching DW relay

 The DW relay was developed especially for digital, electronic smart meters. To save energy, a latching relay is necessary. The DW relay fulfills all demands of this market.

Under the motto "eco ideas", Panasonic hence contributes to the development of efficient, energy-saving smart meters. Besides the market for smart meters, the DW relay can be used in many other applications, especially to switch heating breakers.

Its compact design (24mm x 10mm x 18.8mm (LxWxH)) and low coil power dissipation of 200mW for the 1 coil latching type or 400mW for the 2 coil latching type make this relay extremely attractive for the white goods market, e.g. for use in washing machines, dishwashers and driers, especially to reduce stand-by current consumption. Particularly for this market segment, the DW relay is not only available in an LCP housing (for reflow soldering) but also in PBT, which fulfills the VDE standard EN60335 (glow wire test, creepage resistance).

In principle, the DW relay can be used in the entire "eco market" when power of up to 8A/250V AC must be switched reliably, expanding the already impressive portfolio of latching power relays from Panasonic. Above all for battery-driven applications, the latching DW relay extends the period of use considerably.

Advantageous when designing the DW relay in an application are its 6mm creepage and clearance distance between contact and coil and its impressive breakdown voltage of 6kV between contact and coil. The surge withstand voltage here is a remarkable 12kV.

Samples of the DW relay are available upon request.
