IT (RS, ARM, ARM2) high attenuation isolation transformers for telecom sites
Country: Italy · Model: IT (RS, ARM, ARM2)
IT isolation transformers of the RS, ARM and ARM2 series are made to power telephone exchanges, FM/TV repeaters and other telecom sites. They are high attenuation units made in Italy. They weaken common-mode noise and lightning overvoltages arriving from the mains.
- Series
- RS – with overvoltage protection; ARM – high impulse insulation; ARM2 – class II
- Construction

Description
The winding is concentric and recessed, and the output impedance is low. This construction gives high attenuation of common-mode noise and lightning overvoltages, so the sensitive equipment of the station does not receive pulses from the supply line. The RS series carries overvoltage protection. ARM stands out by its high impulse insulation between the mains and the load, and ARM2 is built to class II. The transformers belong to the Power Quality line and are made for telecommunication sites, where a supply interruption or an equipment fault is costly.
How to choose
The choice starts with the series. Take RS where lightning and switching overvoltages occur at the input, ARM where high impulse insulation between mains and load is needed, and ARM2 where a class II design is required. Power rating is not given in the description, so confirm it with the manager. For a general industrial load rather than a telecom one, look at the ITT dry isolation transformers for 1–1600 kVA with a K-factor from 4 to 50.

FAQ
Which sites are the IT transformers of the RS, ARM and ARM2 series meant for?
They power telephone exchanges, FM/TV repeaters and other telecom sites that need a clean supply free of noise.
What does high attenuation mean in an isolation transformer?
The transformer weakens common-mode noise and lightning overvoltages coming from the mains. The recessed concentric winding and the low output impedance serve this purpose.
How do the RS, ARM and ARM2 series differ?
RS has overvoltage protection, ARM stands out by high impulse insulation and ARM2 is built to class II. The series is chosen by the insulation and protection requirements of the site.
Where are the IT isolation transformers for telecom made?
They are made in Italy. The transformers belong to the Power Quality line, meaning equipment for supply quality.
Which transformer suits an industrial load instead of a telecom site?
Look at the ITT low voltage dry isolation transformers for 1–1600 kVA, whose windings are made of aluminium or copper.
