It operates on a 240V input with the ability to provide up to 12% above line voltage, ensuring versatile power control with minimal waveform distortion. Backed by a 1-year manufacturer warranty, it’s engineered for professionals needing reliable, adjustable voltage in industrial and scientific settings. ## Description Measuring range: 0 - 270 volts 8 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: Good except few minor... - Accuracy is little off and having a physical switch would be better Review: Quality of work menship is bad. It developed intertirn short in the winding and burnt. - It was not a good product, it failed with in a month. The other ones of other make I bought few years are still working. ## Features - Dimmer Variable Transformers, are designed for use on top of a table. These variacs are highly efficient, with no waveform distortion. This is rated at 8A for constant current loads , Maximum capacity of 270 V. Input Voltage : 240 Volts 1 Phase A.C. 50 HZ And Output Volate : 0-270 Volts .Overall the tapping arrangement permits an output voltage of 0 to line voltage or 12% above line voltage. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0834FG5TL | | Best Sellers Rank | #28,624 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #487 in Voltage Testers | | Brand | DENKO | | Brand Name | DENKO | | Current Rating | 8 Amps | | Customer Reviews | 3.5 out of 5 stars 22 Reviews | | EU Spare Part Availability Duration | 1 Years | | Manufacturer | H.K.ENTERPRISES (DELCO) | | Maximum Frequency | 50 Hz | | Minimum Frequency | 50 Hz | | Model Number | 6395977031 | | Mounting Type | Surface Mount | | Part Number | HKVAR8AC | | Power Source | Corded Electric | | Power Source Type | Corded Electric | ## Product Details - **Brand:** DENKO - **Current Rating:** 8 Amps - **EU Spare Part Availability Duration:** 1 Years - **Mounting Type:** Surface Mount - **Power Source:** Corded Electric ## Images ![DENKO Variac/Dimmerstat/Auto transformer Single Phase 0-270V 8 Ampere closed Type with one year manufacturer warranty and 18% GST - Image 1](https://m.media-amazon.com/images/I/71MOmxTbx6L.jpg) ![DENKO Variac/Dimmerstat/Auto transformer Single Phase 0-270V 8 Ampere closed Type with one year manufacturer warranty and 18% GST - Image 2](https://m.media-amazon.com/images/I/71dKPJhwN4L.jpg) ## Questions & Answers **Q: Are spare carbon brushes available?** A: Spare carbons are usually not included with the order.
