High Isolation Ethernet Magnetic Transformers

Pulse Electronics High Isolation Ethernet Magnetic Transformers meet IEEE 802.3 specifications and feature a compact footprint for use in space-restrictive appliances. These transformers offer high isolation for robust applications that require more isolation than traditional LAN applications. They provide safety isolation of up to 6kV and are ideal for both industrial and medical applications. The transformers come with multiple options for working voltages, isolation voltages, and surge/impulse. Pulse Electronics High Isolation Ethernet Magnetic Transformers also meet functional, basic, supplementary, and reinforced insulation requirements. Typical applications include 2-phase and 3-phase electricity meters, battery management solutions, AC motor drives, MRI machines, CPAP machines, and dialysis equipment.
