Customer demand
|
|
|
To supply our sensitive electronics the transformer may by no means transmit mains disturbances. The power supply voltage has to consist of four galvanically isolated circuits. A choke with high inductance is supposed to increase the interference immunity even more. For an easy wiring it would be preferred, if the transformer had terminals.

Solution
|
|
|
We build a toroidal isolating transformer conform to EN 61558 2-4 with very low standby current. The toroidal transformer has one primary and one secondary screen. Both screens are isolated from each other with a 5 kV separation. Transformer, choke and terminals are held together by a mounting panel. To avoid heat accumulation a central hole for ventilation is available.
