  • SCR triggering with controlled gate pulses.
  • Change of firing angle in response to the change in reference voltage
  • Functioning of Signal Conditioner and Pulse Generator IC TCA-785.


Features:
The board consists of the following built in parts:
01. + 15V, +10V D.C. at 50mA, IC Regulated Power Supply internally connected.
02. + 5V D.C. at 50mA, IC Regulated Power Supply Isolated.
03. Synchronising Signal.
04. 24V at 300mAA.C. supply.
05. Signal Conditioner and Pulse Generator IC TCA-785.
06. Op to Coupler.
07. SCR 100V/1Amp.
08. Transistor BC-107.
09. Adequate no. of other Electronic Components.
10. Mains ON/OFF switch, Fuse and Jewel light.

  • The unit is operative on 230V ±10% at 50Hz A.C. Mains.
  • Adequate no. of patch cords stackable 4 mm spring loaded plug length ½ metre.
  • Good Quality, reliable terminal/sockets are provided at appropriate places on panel for connections/observation of waveforms.
