We offer a full standard line of epoxy cast isolation transformers with standard primary voltages ranging from 120 v to 240 v isolation voltages of 30 kvdc or 50 vkdc standard va ratings from 100 va to 1000 va and capacitance from 70 pf to 140 pf.
High isolation voltage ethernet transformer.
An isolation transformer is a transformer used to transfer electrical power from a source of alternating current ac power to some equipment or device while isolating the powered device from the power source usually for safety reasons.
No conductive path is present between source and load this isolation is used to protect against electric.
Isolation transformers provide galvanic isolation.
The transformer isolation and the termination network provide protection against common mode surges.
Poe operates in the lower voltage telecom range generally in the 36 57 v range but up to 73 v typically over category 5 cat 5 ethernet cables.
They have been certified by ul to comply with ul60950 1 2 edition by can csa c22 2 no.
60950 1 07 2 edition and by tuv to comply with en61558 1 and en61558 2 16 with reinforced insulation.
Available in multiple package speed and poe rating options.

High isolation ethernet transformers for pulse electronics networking introduces a new series of high isolation ethernet transformers specifically designed to meet the stringent requirements of medical and industrial applications where equipment functionality and safety are key.
This gives poe a safety advantage over standard line voltage 110 220 v power outlets.
10base t and 100base tx use two of the pairs one transmit and one receive pair while 1000base t requires all four pairs both transmitting.
Pulse s switch mode high isolation transformers are rohs compliant and meet standard eia481 requirements.
In reality many commercially available transformers will actually standoff transient voltages in the 4 8kv range before the isolation is breached.
As we noted transformers in ethernet applications have a minimum isolation voltage of 2 1kv.
4000vrms isolation voltage is guaranteed to.
