Product Code : SCL-EELE-12827
Indian Lab Suppliers supplies the Single Phase Controlled Rectifier with Cosine Firing Scheme (Product ID: 12827) as part of its electronics engineering lab equipment range. It is a trainer for single-phase controlled rectifiers fired by the cosine-wave (cosine crossing) method.
Quick Answer
In the cosine scheme the firing instant is set where a cosine reference meets the control voltage, which makes the average DC output vary linearly with the control input. The board applies this to a four-SCR assembly (400 V / 2 A each) with gradual firing control up to 180°, and students wire half-wave, full-wave mid-point and fully controlled bridge rectifiers in common-anode, common-cathode and asymmetrical forms. Built-in 0-15 V and 18 V-0-18 V AC sources, nine test points and 2 mm sockets are fitted. It runs on 220 V or 110 V, 50/60 Hz.
