## Description

Measuring range: 0 - 270 volts 3 Amperes For Mounting on table top products, high voltage tester etc. DENKO Variable Auto Transformer is meant to operate from a input voltage of 240 V and can provide the output from 260 V to 270 V by simple transformer action. If operated below 240 V, let say 200V then output voltage capacity will also decrease to 230V to 240V. If operated at 220V then output voltage capacity will decrease to 245V to 255V. Therefore, check your input voltage to get better output voltage.

Review: copper wire used - good product
Review: High price - Product quality is not better than average, finishing is below average, connection diagram is messy, only aliens can understand their diagram, very simple phase, neutral, input, output should be stated corresponding A, B, C, D, which is printed on variac, but they have confused it in diagram, even 5th class guy can make clear diagram than denko diagram. Hope they will improve their diagram which can understand by layman's.

### ⭐⭐⭐ Not so happy with the product for two main reasons.
*by P***R on 4 November 2022*

Not so happy with the product for two main reasons. Firstly the connection diagram and corresponding marking on plate is very very confusing to a new person and for wrong connection there is possibility of burning of the transformer. Secondly the wiper is not smooth on the surface of auto transformer as some coils are overlapped causing hindrance to smooth movement of wiper. I was in favour of returning the product but compromised with this drawback to avoid hassles of return as the product is very heavy in weight.
