Product catalog summary
Overview: The document discusses the TK5IN series of single-phase isolation transformers by POLYLUX, designed to address issues in installations lacking a neutral line. These transformers are particularly useful for residential equipment like EV chargers, aerothermal systems, boilers, and biomass equipment.
Specifications: The TK5IN series features low inrush current (<=5In), high performance (>95%), low losses, and quiet operation (<40dB). They are available in power ratings from 2 kVA to 40 kVA and come with various protection ratings (IP00, IP23, IP54/65) and IK ratings (IK08, IK10).
Applications: These transformers are used to create a neutral line in installations, converting two-phase systems to single-phase systems. They improve power supply quality and ensure equipment warranties are maintained.
Manufacturing Characteristics: The transformers are housed in metal boxes with high corrosion resistance, painted with RAL7035 polyester resin. They include lifting elements and detachable covers for easy installation and maintenance.
Technical Features: The transformers operate at standard voltages of 230V input and output, with a frequency range of 50-60 Hz. They are designed for continuous operation and feature natural cooling. The insulation classes vary based on power rating, with Class F for lower ratings and Class H for higher ratings.
Performance and Protection: The transformers include input protections with B or C curves and rated current. They are tested to comply with IEC/EN standards and feature anti-flash varnishing for enhanced insulation and noise reduction.
Additional Features: Options for customization include different IP and IK ratings, cooling methods, and additional protective measures like anti-condensation systems and temperature control. The transformers are certified by CE, DNV-GL, BV, and UL.
Conclusion: The TK5IN series by POLYLUX offers a reliable solution for installations requiring a neutral line, ensuring optimal performance and protection for residential electronic equipment.

Low inrush current transformers (-2

Single-phase isolation transformers with low inrush current (<=5In) Our homes are equipped with energy-saving installations increasingly. Despite the fact that, according to the regulations, three-phase installations should have 400V with neutral and single-phase installations should have 230V F+N, in some areas we find three-phase or single-phase installations without neutral (two-phase installations). The problem that arises because of these installations is that the SATs warn that, if the power supply is not carried out correctly via the neutral, equipment such as EV chargers, aerothermics,...

Single-phase transformers TK5IN SERIES Isolation · Input 230 V · Output 230 V Manufacturing characteristics The TK5IN transformers are mainly used to isolate circuits and increase or reduce the output voltage if this is requested as a special assembly. They are also used to change the installation neutral system for changing from a twophase (PH + PH) to a single-phase network (PH + N) (this case means creating an artificial neural) or vice versa. In installations with a certain amount of electrical noise, the TK5IN series helps improve the electrical network quality in secondary. For example:...
