Design
The WS4 series 4W audio distribution transformers are designed for the speaker side of a voltage speaker distribution system.

Continuous Use Design
This series is designed to operate continuously.

Primary (Input)
Designed for a 25V, 70V, 100V, or 140V speaker distribution line.

Secondary (Output)
Designed for a 4 or 8 Ohms speaker.

Magnet Wire
All units are wound with the finest virgin copper magnet wire. All windings use heavy insulated wire to provide excellent manufacturing yield, lower customer cost and superior life.

The Core
EDCOR uses the finest M6 line grain oriented steel cores. Each unit is hand stacked to assure at least 92% stack.

The Bobbin
Injection molded Nylon 6/6 with the addition of 30%-35% glass fibers. The addition of glass fibers allows a higher heat deflection temperature and it brings the material to a class HB UL temperature classification.

Termination
The terminations are 0.187" (3/16") spade terminals. These terminals can be connected with 0.187" (3/16") quick disconnects or can be soldered to.

Mounting
This unit comes with steel zinc plated channel/frame for mounting with the use of two screws. See dimensional drawing.
