Celduc's updated program of solid state relays can be divided into three groups:
- random or direct switching for e.g. motors
- zero cross or zero crossing switching, with integrated protections and thus suitable for most loads
- zero cross or zero-cross switching, optimized for ohmic loads, such as heating elements.
These relays are supplied in a slim sightpac housing only 45mm wide x 100 x 48mm. Here the maximum current is 20A at 640Vac.
For applications with higher currents from 24 to 85A at 600Vac, the SSR is housed in the flat cell3pac housing of 77 x 100 x 35mm housing. This has advantages especially in versions with forced cooling, where then the construction height is quite low compared to other providers. Connections can be made with spring pressure terminals or screw terminals.
In addition to solid state relays with an on/off function up to 125A, Celduc also offers proportional relays that emit sinuses with either phase cut or a pulse train and can thus control heating elements, among other things.
And especially for motor controls, three-phase reversing relays are also available.
Celduc's relays are optionally equipped with a substructure heat sink, depending on the duty cycle, duty cycle and power demand. We can calculate this for you.
