• If you impact the core contact surface, internal core material could be damaged. • Additionally, CTs are deliverable with customized output lead cable.

JS series of split-core current transformer offers XXXmA at secondary from sensed primary current for metering application. Without using secondary CT inside of meter, it enables one meter to be adopted for various current rating by only changing primary CT so it makes compact meter design and reduces developing cost. Also, over-voltage protection circuit is included to offer safe, fast and cost effective installation. Especially JS10FL can be installed at secondary of 5A output primary CT to compare meter's accuracy.

HOW TO USE

SPLIT-CORE CURRENT TRANSFORMER

JSXXSL-XXX/XXXmA series

• Core contact surface is waterproofed, however if it gets rusty, you could reuse after removing rusts with spraying WD-40 or CRC5-56 on the rusted side. • Do not use any other chemicals except WD-40 or CRC5-56 on housing or any parts.• Customizing out put lead wire

JS series of split-core current transformer offers XXXmA at secondary from sensed primary current for metering application. Without using secondary CT inside of meter, it enables one meter to be adopted for various current rating by only changing primary CT so it makes compact meter design and reduces developing cost. Also, over-voltage protection circuit is included to offer safe, fast and cost effective installation.
