The S2EX-Z-24-3 with Converter is a power supply isolator and repeater manufactured by LABOR-ASTER. It has a DIN rail mounting system and an extended temperature range of -30°C to +70°C. It has a 24VAC/DC input voltage and 24VDC output voltage, providing isolated power supply for fieldbus devices with up to 24V DC power supply. It also has a built-in surge protection that can protect communication network from external transients. Moreover, it has a double-sided isolation, which prevents the common-mode pulsations from being transferred from the power unit to the communication network. Finally, the converters feature surge protection, interference protection and EMC suppression.
