Transformer Rectifier

The transformer rectifier works to provide power to the magnet at the correct Amps. This is dependent on magnet design, input voltage, and ambient temperature.

Additional Features:

The tank is a fully welded steel enclosure to IP65, and has a bolted lid for easy access to oil and components. For easy oil changes, the oil level gauge is fitted to the front of the tank and a drain plug is provided.
The terminal chamber on the front of the tank houses incoming AC and outgoing DC terminals. Taps are located inside the chamber, allowing outgoing DC voltage to be changed.
Double wound transformer to BS EN 60076.
The silicone diode, full wave bridge connected rectifier is stack mounted on an aluminum heat sink to BS 4417 ABCD.
Diode protection is equipped with fast-acting semi-conductor fuses. The surge suppression is fitted to protect diodes against surges from the magnet coil following switch off.
Steel is finished with one coat of primer and two coats of RAL high performance alkyd enamel.

Description

Optional Extras:

Starter box that features a start/stop button, a lockable isolator, and a current sensing relay to detect magnet low power and overloads, with terminals provided for remote access.
To prevent side spillage, 150mm high spillage rings can be fitted to the end flanges. These rings are fabricated in sections, allowing easy replacement if damaged.
Drum can be mounted onto a base frame and supplied complete with geared motor, chain dive, and guard.
To reduce downtime, a split platewheel can be provided for easy replacement. Platewheel may be ANSI if required.

Applications:

Electro Drum Magnets are widely used in the recycling industry, especially in environments that are particularly difficult and arduous. Some examples include:
Automobile and vehicle recycling and recovery facilities
Municipal waste and recycling facilities
Steelworks recovery facilities
