Control unit six pulse, digital

735135

Description

Trigger pulse generator with analogue and digital interface (8 bit) for connection to personal computer with CASSY interface in line-commutated, single-phase and three-phase rectifier and inverter circuits, as well as in AC and three-phase controllers. The control unit is adapted to the converter circuit using several switches with the following options:

Single pulse or pulse train operation possible
Secondary pulse can be switched off (after 60°)
Phase shift can be set for various natural
commutating points: 0°, 30°, 60°

Reliable gate triggering of the valves is guaranteed for even small loads thanks to powerful gate trigger pulses and large voltage-time areas (500 µVs) of the trigger pulse. Rotating field monitoring:

Green LED when rotating field is clockwise
Red LED when rotating field is anti-clockwise
or for phase failure.
