Current Transformers
Current Transformers
Outline
NEC TOKIN current transformers are AC sensing
elements that are suitable for current controll and
overcurrent protection.
Features
• Compact, inexpensive, with high output voltages
• Broad-frequency bandwidths (50 Hz to 100 kHz)
• Easy mounting on printed circuit boards
• Use flame-retardant materials (UL94V-0 class)
Applications
• Electromagnetic cooking appliances, microwave ovens,
airconditioners and other home appliances
• Current regulation in office automation and industrial
equipment
• High-frequency switching power supplies
