Thyristor unit
for analogue control
mounted on rail to EN 50 022 or wall-mounted
Brief description
Thyristor units are used in all applications where larger resistive and inductive loads have
to be switched, for example in industrial furnaces and in plastics processing. The thyristor
unit consists of two thyristors connected in inverse parallel, the isolated heat sink and the
control electronics. Thyristor units up to 50A load current can either be snapped onto a
35 mm rail or wall-mounted using a mounting plate. Units from 75A load current can only
be wall-mounted. Depending on the settings of the internal switches, the thyristor units
operate either in phase-angle mode with adjustable current limiting, or in burst-firing
mode. In burst-firing operation, the start of the first half-wave can be partly cut back to
permit operation on transformer loads. A subsidiary control, which can be selected as U
2 ,
P or I 2 , ensures that fluctuations in the supply voltage do not affect the control loop during
the process. The control range can be restricted by attenuating the input signal, and a
base load can be set using an external potentiometer. An economy circuit can be used on
multi-phase loads in burst-firing operation. In phase-angle operation, the phase angle set
by the controller is approached slowly, starting from 180 degrees, in order to avoid high
inrush currents (soft start). The thyristor units conform to VDE 0160 5.5.1.3 (5/88) and VDE
0106 Part 100 (3/83). The unit has to be grounded in accordance with the requirements of
the local power supply authority.
