Finder Relays Handle Rigours of Photovoltaic (PV) Applications

February 16, 2011

Finder.jpg

Finder has extended its relay range with versions designed to suit photovoltaic (PV) inverters, domestic appliances and other equipment needing reinforced insulation, high ambient temperature handling and full disconnection contacts.  The latest product introductions comprise the 45.31 16A rated mini PCB relay and 3 special variants of the 66 Series 30A rated power relays.

With an extended 3mm contact gap, the single pole NO 45.31 relay meets the requirements of the EN60730-1 standard for household use and is rated for operation at an ambient temperature up to 105ºC.  It has a high sensitivity 24V DC coil rated at 360mW.  In common with the 66 Series specials, the 45.31 has been designed with an 8mm clearance and creepage distance, ensuring safe separation of supply and output, and reinforced insulation between coil and contacts, meeting the requirements of EN60335-1 (VDE0700).

The 2 pole NO (DPST-NO) 66.22-x600, 66.22-x600S and 66.82-x600 30 amp power relays ensure a contact gap separation of 1.5mm, fully meeting the requirements of the VDE0126-1-1 standard for PV inverter applications.  In addition, the 600S variant provides a 5mm airgap between relay base and PCB for extra cooling particularly in systems where forced air cooling is employed as with many PV inverters.

For added flexibility, the 66 Series relays provide the options of PCB and flange mounting and Faston 250 terminations.  A 35mm rail mounting adaptor is also available.  A wide range of coil voltages is offered, spanning from 6V through to 125VDC.

February 10, 2011

K&N Logo B.jpg

A growing requirement for DC switch disconnectors for solar photovoltaic (PV) power supply systems has motivated Kraus & Naimer to introduce a brand new range of disconnectors specifically designed for this particular DC application.

With rated operational currents from 16 amps to 64 amps and voltages from 450 to 800 using a utilization category of DC-22A, a solution for most isolator applications within the solar photovoltaic market can be found.

                                                                                                                                                                        

Available in a totally insulated enclosure with the option of a red/yellow or grey /black padlockable handle and with a degree of protection to IP 66/67 they can be installed in the most arduous of environments.

To complement this series a complete range of AC switch disconnectors is also available in totally insulated enclosures, this enables the contractor to obtain his switch disconnector requirements for the entire installation from one source.

A new up to date catalogue giving part numbers and technical details is available on request.
