Phoenix contact manufactures single-phase electronic load relays model elr 1/25-240 and elr 1/35-600 which can be used in ac voltage networks wherever silent switching, high switching frequencies and unlimited mechanical life is required. These single-phase electronic load relays are available with robust power semi-conductors switch in zero-voltage crossing which help in producing no additional high-frequency interferences. These single phase electronic load relays model elr 1/25-240 and elr 1/35-600 are insensitive to shock loads and vibrations and use in aggressive, polluted environments is unproblematic. These electronic road relays are applicable in production machines, temperature controllers, conveyor equipment and light and lighting systems.
