Description

Solid State Relays

Using solid state relays, it is possible to achieve a very smooth power flow to the load. Switching cycles as low as 1 second are normal using these devices. When mounted correctly with heat transfer paste on a correctly sized heat sink, they will switch reliably for many years. Please seek advice if using close to maximum current rating. A red LED shows when power is on (where fitted).

Fan cooling is recommended for applications above 40 amps continuous

  • Zero cross switching
  • Internal RC snubber
  • Input / output  optical isolation 600V
  • AC-90 to 280V rating at each current capacity
  • 3-32 V DC trigger voltage or 90-280V AC according to model
  • Trigger current draw 10-20mA depending on voltage for DC  2-5mA for AC
  • Turn on voltage 3VDC  or 90 VAC
  • Turn off voltage 1 VDC or 10 VAC
