SCR And AC Phase Control
Product Code : JA-PET-1415
The SCR and AC phase control trainer is a power electronics board for studying how SCRs are triggered and used to control AC power, from simple resistance triggering to UJT trigger circuits with ramp and pedestal control. It carries three SCRs for half-wave and inverse-parallel full-wave circuits, a bridge rectifier with zener regulator, a UJT 2N2646, a 1:1:1 pulse transformer and potentiometers for the ramp and pedestal settings. It runs on 230 V AC mains (SKU JA-PET-1415).
