Description
ЛАТР is an adjustable autotransformer. It connects to a 220 V supply and changes output voltage smoothly within 0–250 V. Used for commissioning and testing electrical equipment in laboratories and training classrooms, to apply or gradually raise a set voltage. ЛАТР-2,5 is rated for a nominal load current of 10 A, no-load current is up to 0.5 A. Operating mode is continuous, working position is any. Operation is allowed up to 2000 m, with current reduced by 2.5 % for every 500 m. There is no galvanic isolation between supply and load, which is taken into account when choosing a test circuit. The designation varies: ЛАТР-2,5, ЛАТР 2,5, ЛАТР-2.5, LATR-2,5, and also ЛАТР-1,25, ЛАТР 1,25. These are the same devices.
How to choose
Choose by load power. For currents up to 10 A use ЛАТР-2,5; for a smaller load, ЛАТР-1,25 is enough. Check the model permissible current and operating conditions against the passport. Ask a USK ENERGY manager about version, kit and verification.

FAQ
Are ЛАТР-2,5 and LATR-2.5 the same?
Yes. ЛАТР-2,5 is the correct spelling in Cyrillic. Variants ЛАТР 2,5, ЛАТР-2.5 and LATR-2,5 are common, but they name one autotransformer. The same applies to ЛАТР-1,25.
What voltage does ЛАТР provide?
Primary voltage 220 V, output voltage is smoothly adjustable within 0–250 V.
What current can ЛАТР-2,5 withstand?
Nominal load current 10 A, no-load current up to 0.5 A.
Can ЛАТР be used in any position?
Yes. Operating mode is continuous, working position is any.
How does altitude affect it?
Operation is allowed up to 2000 m, with current reduced by 2.5 % for every 500 m.
