Single-phase isolation transformers with low inrush (<=5In)
Advantages
Dry type transformer.
Efficiency higher than 95%.
Low losses, reducing the consumption of the installation.
Low noise < 40Db
Low connection peak between 3 and 5In, for B or C curve input protection and at its rated current.
Maximum overload 200% 2 seconds.
Finished in anti-flash varnish, by immersion offering:
- Protection against corrosive environments.
- Increased electrical insulation.
- High compacting power.
- Reduction of the noise level.
- Increased product life.
Safety class I.
IP-65 up to 16 kVA and IP-54 as from 20 kVA (for IP-65 degree consult us), metal enclosure painted with polyester resin RAL 7035 (cat. C4 ISO 12994-2).
Includes cable glands and silent-blocks.
Possibility of customized manufacture if different specifications than standard are suitable.
Applications
- TK5IN transformers are used when galvanic isolation is required in single-phase installations.
- They can be used to switch from Phase-Phase to Phase-Neutral.
- To disconnect the neutral from earth in those installations with grounded Phase-Neutral.
- In installations where we have loads that in normal operation have a high level of earth leakage, the TK5IN transformers can isolate them, thus avoiding the untimely jump of the differential.
- In installations where there may be small voltage peaks or electrical noise, TK5IN transformers help to improve the quality of the signal that feeds the loads.
- In outdoor installations where weather conditions are adverse, the TK5INZ version with IP-54/65 outdoor use offers an optimum solution.
Available accessories
- PT100 sensors.
- Bimetal sensors.
- PTC sensors.
- Temperatura control unit.
- Metal enclosure painted with polyester resin RAL 7035 (cat. C5 ISO 12994-2).
