Connection Diagrams of SSR

SSR or Solid State Relay or Electronic Relay

Connection Diagram of AC Control SSR

This is a Thyristor Based Normally Open 230V Switch that can be turned on / off at a fast rate. This switches at Zero Crossover .Built In Snubber reduces EMI and protects the SSR. USE SAME PHASE FOR I/P & O/P.

• No moving parts hence no wear and tear.
• Dissipates Heat when in On Condition.
• Use adequate Heat Sink or SSR will fail. ( 10g / Amp)
• Dissipation is 1.5 Watts per Amp thru Load.
• Input to Output is optically isolated 2kV.
• This one is AC 230V Control AC 230V N.O. Output.
• Off state snubber Leakage is around 5 mA.

Notes -

The Termination's of High Current Lines going to Load must be very tight and crimped. Loose contacts will Spark and cause Fire.

Fuse Rating of HRC Fuse - High Rupture Capacity (HRC) Fuse is Safe and Reliable. 5kW Heater at 230V is 5,000 / 230 in Amps of Fuse Rating.

Connection Diagram of SSR DC 3-30 Control / 230V AC N.O.

Use 12V DC for Best Results. This one is DC 3-30 Control AC 230V N.O. Output. Rest same as above.

Connection Diagram of DC PCB SSR

Diagram of SSR 5000 DC 3-30 Control / 230V AC N.O  3A.

This is a Thyristor Based Normally Open 230V Switch that can be turned on / off at a fast rate. This switches at Zero Crossover . Use 5V DC for Best Results.

• No moving parts hence no wear and tear.
• Dissipates Heat when in On Condition 5 Watts @ 3 Amps.
• Mount with adequate Air Ventilation for 3 Amps.
• Dissipation is 1.4 Watts per Amp thru Load.
• Input to Output is optically isolated 1kV.
• This one is DC 3-30 Control AC 230V N.O. Output.
• Off state snubber Leakage is around 1 mA.

Notes -

The Termination's of High Current Lines going to Load must be very tight and crimped. Loose contacts will Spark and cause Fire.

Fast Blow Fuse is to be used. Use a 2 Amps Fuse with Holder in the Hot Line
