Data Sheet
Description
Single-phase electronic load relays are used in AC voltage
networks wherever silent switching, high switching
frequencies, and virtually unlimited service life are required.
The rugged power semiconductors switch at the zero
voltage crossing and thus do not generate any additional
high-frequency disturbing pulses.
The modules are resistant to shock loads and vibrations –
even use in aggressive, polluted environments does not
present a problem. Common areas of application are:
– Production machines
– Temperature controllers
– Conveying systems
– Light and lighting systems
Make sure you always use the latest documentation.
