Introduction de produit

The isolation transformer uses separate primary and secondary windings on a laminated magnetic core. Encapsulated or varnish-impregnated coils resist moisture and vibration, and an optional copper electrostatic shield is bonded to earth between windings to attenuate common-mode noise. The assembly is housed in a non-ventilated or guarded enclosure with clearly separated input and output terminals.

Key Features

Physically separate windings prevent a direct conductive path between input and output.

Encapsulated coils support consistent insulation and lower audible vibration.

An interwinding shield diverts coupled high-frequency noise to protective earth.

Finger-safe terminal blocks organize primary taps and secondary connections.

Rubber isolation mounts reduce mechanical hum transmitted to the floor or wall.

Préoccupations du client produit

Sensitive equipment can be affected by ground noise, voltage mismatch and transformer hum even when the nominal supply remains available.

Common-mode electrical noise enters instrument reference circuits.Galvanic separation and an optional grounded shield reduce capacitive noise transfer.

A transformer enclosure transmits audible hum into a quiet laboratory.A welded core, coil impregnation and resilient mounting pads limit vibration.

Exposed terminal studs create accidental-contact risk.A guarded wiring compartment uses labeled finger-safe connectors.

Dust enters an open ventilated enclosure near a clean process.An encapsulated non-ventilated configuration closes the core and coil from room air.
