AN3 3 Phase Current Transformer : 100A fully encapsulated unit for Industrial & distribution applications.
Cost-efective rugged design, complete with 2.5M lead
ASM Series 50/60Hz 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.
AC Series Low Cost 50/60Hz Current Transformers for applications such as Sensing Overload Current, Ground fault detection
, Metering, Analog to Digital Circuits.
FSD Series 5A Tape Wound Current Transformers suitable for measuring AC currents from 60A to 2500A with 5A secondary windings.
Accuracy Class 3, Rated system voltage 0.72kV, Conforms to IEC44-1 (EN60044-1)
Cost effective solution where conventional busbar mount types are not suitable.
Rugged construction, unaffected by vibration, supplied with 3 Metre long flying leads for versatility of mounting location.
Applications include : Current monitoring in Generators, Switchgear, Distribution & Control panels
AS Series Current Sensors are designed as a low cost method of controlling,
monitoring or measuring AC currents at frequencies from 20kHz to 200kHz.
The sensors serve as feedback elements between the output and pulse control circuitry providing
accurate regulation of switch mode power supplies.
