DTHB04404S Drive Isolation Transformer Three Phase 60 Hz 575 Delta Primary Volts 460Y/266 Secondary Volts

DTHB04404S575 Delta Primary Volts - 460Y/266 Secondary Volts - All Acme Drive Isolation Transformers (DITs) above 7.5kVA are wound with strip windings to ensure the lowest possible eddy current losses. A three leg wound core is used by all our DITs. This exceptional design has very low losses and silent operation. Both these features combine to significantly reduce losses and operation costs when compared with other kinds of constructions. All Acme DITs including the 220kVA and up to have copper terminations. The transition from aluminum strip coil conductors to copper conclusions is actioned by a bonding procedure known as "Koldwelding" This process was used by Acme for over 25 years to supply a trouble-free, permanent bonding of both metals.Type 2 Enclosure without weather shield.3-Phase 60 Hertz180°C and 220°C insulating material systemsAcme’s reinforced center assemblies accentuate quiet operationNominally 6% impedanceDesigned for use with DC drives, flexible frequency or ACTotal capability taps are featured on all units. On 27 through 660 kVA units, taps are 2-2 1/2% ANFC and 2-2 1/2% BNFC.All drive systems that are standard are covered by complete range of kVA evaluationsAmple wiring compartment for easy cable entryOptional wall mounting brackets for certain sizesAnxiety alleviation: Acme uses strip conductors (above 7.5 kVA) instead of wire for a DIT string that readily accommodates the acute electric and mechanical stresses found in today’s AC & DC motor drives. The inherent outstanding line isolation of these transformers is further improved with the extra protection of Acme’s Electrostatic Shield — .Lower declines: The harmonic currents generated by AC & DC drives increase eddy current losses (heat) in transformer windings. The thicker the greater the reductions, the winding conductor. Acme uses one turn per layer of thin strip conductor which supplies lower eddy current losses than similar wire wound units. Declines that are lower = cooler operation and l
