LAN transformer

In the fields of professional audio, video transmission, and stage lighting control, a seemingly minor connectivity issue can bring a meticulously planned performance or important event to a standstill. Vibration, frequent plugging and unplugging, and com

1、 Device Introduction A current transformer (CT) is a device used to measure and protect the current in a circuit. It converts high current into low current through the principle of electromagnetic induction for the purpose of measuring and protecting ci

VOOHU Electronics has launched a single-pair Ethernet (SPE) solution based on the JLSEMI JL31X1.This solution is used for single-pair twisted-pair communication, supporting RMII 100Mbps/GMII 1Gbps data rates and conforming to IEEE 802.3. This design imple

In PoE power system design, the selection of PSE and PD controllers often draws the most attention. However, in real engineering, whether the matching between the power transformer and the LAN Transformer is appropriate directly determines power supply ef
