Bulk Or Fixed Voltage DC Output

Power Rectifier Unit

Where 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.

  • Double Wound Transformers
  • Silicon Diode Rectifiers
  • Analogue or Digital Panel Meters
  • Isolators, MCB’s, Fuses as required
  • Sheet Metal Enclosures
  • Variable Voltage Options

Variable DC Output

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 such a variable DC source.

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.

Special Application Rectifiers – 24 Volt Tail Lift Transformer Rectifier

Tail Lift Power Supply Unit (PSU)

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.

The units are offered in several forms such as floor standing, wall mounting, single and galvanically isolated dual output power supplies to supply one or two docks or bays. The product range is fully customisable to meet whatever requirements the client may have.

Ratings of 24 Volts DC and up to 300Amps per output are available.

Whatever specific needs you may have Admagnetics will be pleased to discuss your requirements with you.
