SWITCHING UNIT TSE

SWITCHING UNIT TSE

• The TSE thyristor switching units are used to switch the load circuits (infrared heaters) and are available in two power stages:
• TSE 40 A, max. 40 A = 9.2 kW at 230 V
  TSE 20 A, max. 20 A = 4.6 kW at 230 V
• TSE thyristor switching units are supplied complete with heat sink and mounting clips for 35-mm standard rails. They are not subjected to any contact wear and therefore do not cause any switching noises. They are easy to install and their service life is virtually unlimited.
• The loads are switched on at voltage zero and switched off at current zero. This means there is no system perturbation.
• The permissible voltage is 24 – 265 V for TSE 20 A and 42 – 660 V for TSE 40 A. A thyristor switching unit must be provided for each phase of a multi-phase connection to a 230/400 V alternating current mains.
• The thyristor switching units must be protected against short circuits with super-agile fuses.
• Transformers cannot be switched due to the Rush Effect.
• Further information and safety information are given in the TSE operating instruction.
