Introduction

Single phase transformers

TEI Type

Single phase transformers from the TEI type are used on energy systems either as security - isolation type transformer or step up - down transformer, in machine control panels, automation panels and etc. Depending on such factors as the specific transformer type, number of windings, core type, output voltage, etc., AST Engineering can provide Single phase transformers for a wide range of requirements.

IEC standard 61558
Rated power 30 - 2500VA
Rated input voltage < 500V
Rated output voltage < 500V
Frequency 50/60Hz
Insulation class F /155 degree Celsius/
Protection grade IP00

TUI Type

Single phase transformers from the TUI Type are commonly used for building into installations and industrial or power engineering devices, like isolating transformers for the supply of medical locations of group II and intended to create an IT system. The transformers are made with Class I or Class II insulation and maximum ambient temperature 40 degree Celsius.

IEC standard 61558
Rated power 0.5 - 40kVA
Rated input voltage < 1000V
Rated output voltage < 500V
Frequency 50/60Hz
Insulation class F /155 degree Celsius/
Protection grade IP00

TZM Type

Encased protective single phase transformers from the TZM type are suited mainly for applications requiring protection against electric shock and high IP grade. TZM is a stationary version, free-standing or wall mounted. The transformers are made with Class II insulation, maximum ambient temperature 40 degree Celsius.

IEC standard 61558
Rated power 50 - 600VA
Rated input voltage < 500V
Rated output voltage < 500V
Frequency 50/60Hz
Insulation class F /155 degree Celsius/
Protection grade IP20-IP65

TA Type

C core/C-core/ transformers from the TA type are wound from cold rolled grain oriented (CRGO) silicon steel used for building into audio devices. Characteristic: Low magnetic loss, low noise, Low cubage, lightweight, high efficiency and etc.

IEC standard 61558
Rated power 10 - 2500VA
Rated input voltage < 1000V
Rated output voltage < 500V
Frequency 50/60Hz
Insulation class F /155 degree Celsius/
Protection grade IP00

TCVM Type

Single phase high voltage transformers from the TCVM type are applied in medical equipment with high potential, negative potential therapeutic apparatus, high voltage ion therapy machines, massage chairs and other medical equipment.

IEC standard 61558
Rated power 10 - 2500VA
Frequency 50/60Hz
Insulation class H /180 degree Celsius/
Protection grade IP00
