The AEM33 is suitable for use with current transformers (CTs) with 5A secondary output. Metering
quality CTs of Class 1 accuracy with a minimum rating of 2.5VA are recommended.
Connections should be made according to the diagrams below.
CAUTION: The instrument is internally fused at 250V 100mA. External fusing is required if
the supply voltage exceeds 250V.
