Panasonic Electric Works DZ-S Power Relays

DZ-S series power relays

Panasonic's DZ-S relay has been specially developed for the switching of the main power supply from the energy supplier to the consumer, one of the main functions in smart meters.

In addition to smart meters, this small-sized relay is ideal for any kind of application where currents up to 90A have to be switched, such as building and industrial automation markets. 

As proven by the conformity to the IEC 62055-31 UC3 standard, the newly developed relay has no problem handling short circuits of up to 3000A. Moreover, this latching type relay is helping to save energy for the whole application. Its compact design (30mm x 38.5mm x 17.5mm (LxWxH)) and low coil power dissipation of 1.5W for the 1-coil latching type or 3W for the 2-coil latching type make this relay extremely attractive for all applications calling for energy efficiency. Here, the reduction of stand-by current consumption is paramount.

In principle, the DZ-S relay can be used in all applications which require a normally open (N.O.) contact to switch loads of up to 90A and 250V AC reliably, thus complementing Panasonic's existing portfolio of latching type power relays. So for applications in smart homes with smart meters and time switches, this relay offers added value for the user.

Different kinds of terminal arrangements can be provided, depending on the layout of the circuit board as well as on the mounting method, Other prominent features of the coil latching relay are a high breakdown voltage of 4kV between coil/contact and a surge breakdown voltage of 12kV.
