Rectifier Units

The wealth of experience and knowledge of Admagnetics highly experienced designers and our flexible manufacturing abilities enable us to offer our customer base solutions to their Rectifier applications.

24 Volt Tail Lift Transformer Rectifier Range

When lorries are standing at a loading bay it is common practice for the bay operator to provide shore-based transformer rectifier units to power the tail lift and similar equipment mounted in the lorry.

This has a significant environmental impact as the lorry’s engine can be switched off for the duration that the lorry is at the loading bay.

Our Tail Lift Transformer range is offered in several forms such as floor standing, wall mounted, single or galvanically isolated, dual output power supplies to supply one or two bays. Ranges of 24V DC and up to 300A are available. Our product range is fully able to be customised to meet whatever requirements you may have.

Bulk Or Fixed Voltage DC Output

When a single fixed voltage output is required diode type rectifier equipment is often employed.

Typically such a unit comprises a rectifier transformer and a diode rectifier, with the precise arrangement being dictated by the required capacities of the unit.

A low-voltage/high-current unit may employ a hexaphase connection with single way diode assemblies, while a high-voltage/low-current unit may require series connected full-wave bridge rectifiers that may be fed from one or two transformers depending on requirements. Two, six and twelve pulse arrangements can be offered.

Variable DC Output

If you need a variable DC Voltage source then the simple addition of a variac or voltage regulating transformer to a fixed voltage unit would provide it.

Variacs and voltage regulating transformers have advantages such as maintaining a high power factor across the full range of voltage adjustment and they experience maximum output voltage ripple only at maximum output voltage. At all other levels of voltage, the output voltage ripple is reduced on a pro-rata basis.

The disadvantage of variac and voltage regulating transformers is that in comparison with semiconductors their speed of response is comparatively slow. Where fast control is required then a phase angle controlled thyristor full wave bridge rectifier should be employed.
