The J&D JM21N-1A series of split-core current transformers offer 1A at secondary from sensed primary current
- Without using a secondary CT inside of meter, users directly connect JM21x series to a meter for high accuracy metering application
- It enables one meter to be adopted for various current ratings by only changing the primary CT so it makes a compact meter design and reduces development costs
- Also, over-voltage protection circuit is included to offer safe, fast and cost effective installation
- APPLICATIONS
- Power meter
- Switch-gear
- Distributed measurement systems
- General sets
- Control panels
- BENEFITS
- Small-size, light-weight
- Simple installation
- Over-voltage protection circuit is installed
- FEATURES
- Steel spring plate, output-terminal, secure locking hinge, one-touch structure is easy to install into existing equipment such as a power distribution board
