Satronix
  Relays : normal Open TYPE 1..., normal Open TYPE 2..., 3 - Phase TYPE...
   
  Solid State Relays
 
3 - Phase TYPE Optically Isolated
  Switches 10 to 40A Loads
 

Features:

  • Available are economical photocoupler isolation which can be connected directly to IC logic circuits such as DTL, TTL, CMOS etc.
  • Zero voltage turn-on; zero current turn-off
  • Dielectric strength (Input & Output to Case) 2500 VAC
  • No noise feedback from output to input circuits
  • No noise due to load current switching at near zero point.
  • Faster switching response.
  • Requires minimum actuation power.

Note:-

  1. Rating is based on a single mounted unit in free air flow. Closely packed units will result in restricted air flow and careful consideration of the ambient temperature will be necessary.
  2. For additional transient over - voltage protection, use metal oxide varistors; and for current protection, use semiconductor fuses.
  3. For load current > 3 Amps external heat sink has to be used. (*Refer to Thermal Derating Curve).
