LATR-1,25 and LATR-2,5 autotransformers "I" with the digital indicator
LATR autotransformers (laboratory autotransformers) single-phase, it is intended for smooth regulation of tension of alternating current of the frequency of 50 Hz or 60 Hz during various electrotechnical works.
Operation of autotransformers is allowed with a height above sea level to 2000 meters. At operation of autotransformers at the height over 1000 m the rated current of loading has to be reduced by 2,5% for each 500 meters of height.
The rated primary voltage of LATR autotransformers - 220 Century.
Regulation limits - 0-250 Century.
Maximum current of loading of autotransformers:
- LATR-1,25 - 5 AND;
- LATR-2,5 - 10 AND.
Idling current with a rated primary voltage - no more than 0,5 And.
Autotransformer efficiency - not less than 94%.
LATR autotransformers have to be reliably grounded.
Operation with the removed cover is forbidden.
LATRY treat devices, unstable short circuit therefore they need to be included in a network which is protected by fuses with current of the fusible insert which is not exceeding respectively 10 And for LATR-1,25 and 20 And for LATR-2,5.
Overall dimensions, mm:
LATR-1,25 - 235 x 130 x 200;
LATR-2,5 - 235 x 145 x 200.
LATR-1,25 - 6,0;
LATR-2,5 - 8,0.
Position of the LATR autotransformer at operation - any, an operating mode - long.
