This is a general-purpose power circuit development panel. This consists of six numbers of thyristors and three numbers of power diodes. Using these devices, one can assemble any combination of SCR power circuits. This unit requires an external SCR trigger circuit with proper conditioning for gate firing. This unit has three fuse holders. The AC power required for enabling the power devices must be routed through fuses as a protective measure for the circuit board components. NOTE: The circuit developer must take adequate precautions while handling this board, as high voltages do exist when high voltage AC power is connected to this device circuit panel. For safety of the operator, it is necessary to have an external circuit breaker as part of AC power inlet connections. Specifications: - Thyristors used : 6 Nos.
- Power diodes : 3 Nos.
- Fuse protection : on 3 lines
- Terminals : 4mm colored terminals for each device
- Patch cords : 4mm banana patch cords required.
