DESCRIPTION

The LO-HF4002 current sense transformers are designed to monitor AC currents. They can be used for
high frequency current sensing, for example in switched-mode power supplies, motor control and electronic lighting ballasts.

 

FEATURES

• RoHS compliant
• 50, 100, 200 & 300 Turn variants
• Primary current up to 40A
• 20kHz-200kHz frequency range

TECHNICAL NOTES
ISOLATION VOLTAGE
All LO-HF4002current sense transformers are tested at 500Vdc for a minimum of 1 second during our standard test procedure.
In addition, as part of our qualification process carried out prior to product launch, the LO-HF4002 demonstrated no isolation breakdown at 10kVdc or 6kVac with a bare conductor as the primary winding. Whilst this does not imply these parts are designed for environments where such high voltages may be present, it does demonstrate the level of isolation voltage these products are able to withstand. Full mains safety isolation can be achieved with appropriately insulated wire on the primary winding.
