Connection Diagram of DC PCB SSR

This is an Application note i used to give with my ssr – app012.pdf – Ananth

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.

PCB SSR Wiring

  • 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.

Dual-Low-Noise-JFET-Opamp-TL072-TI

Dual-Low-Noise-JFET-Opamp-TL072-TI

The JFET-input operational amplifiers in the TL07x series are designed as low-noise versions of the TL08x series amplifiers with low input bias and offset currents and fast slew rate. The low harmonic distortion and low noise make the TL07x series ideally suited for high-fidelity and audio preamplifier applications. Each amplifier features JFET inputs (for high input impedance) coupled with bipolar output stages integrated on a single monolithic chip.

  • Low Power Consumption
  • Low Input Bias and Offset Currents
  • Low Noise
  • High Input Impedance JFET Input Stage
  • High Slew Rate – 13 V/┬Ás Typ
  • Common-Mode Input Voltage Range Includes VCC+
