ASM Series • Current Sensor for 50/60 Hz
ASM Series current sensors operate as the sealed secondary of a current transformer while the conductor
carrying the current to be measured functions as a one turn primary. Measurement accuracy can be
improved by increasing the number of primary turns. Applications include detection of branch circuit
overload and load drop or shutdown.
Features
• Fully encapsulated for optimal PC board mtg.
• Mains frequency of 50/60 Hz
• Primary current ratings from 1 to 100 Amps
• Primary to secondary isolated to 2500 V AC
• Operating temperature range: -40° C to +120°C
