It supports selectable input voltages of 110/120V or 220/240V and outputs 110V or 220V AC, featuring all-range fuse protection for enhanced safety. Weighing 76 pounds with a floor-mount design, it requires professional installation to ensure reliable, heavy-duty performance across diverse electrical environments. ## Description *** Item does NOT come with an Instuction Manual*** Must be installed by a Certified Electrician*** Made by one of the leading manufacturers in the industry, the Topow ST Series step up / step down voltage transformers offer you a safe, reliable, affordable and convenient solution to converting voltages from 110-120 volts up to 220-240 volts, or from 220-240 volts down to 110-120 volts for both home use and industrial applications. The ST-10.000 is rated at 10.000 watts maximum. It also uses a protective standard fuse for extra safety. The manufacturer recommends you purchase a transformer that is 25% higher than the wattage you need. You should know that you will never damage your appliance with a higher voltage transformer, however if you buy one that is not powerful enough, it will not work. Remember to leave at least a 100% slack for the transformer. Some items, such as laser printers and power tools, spike when you turn them on. For these types of situations you need to buy a transformer that is at least 3 times the item's capacity. This is a very heavy transformer, it should be handled with a hand-truck or dolly. Handles are made of plastic and should not be used to lift the item up. ## Features - Input Voltage: 110/120/220/240 Volts /AC Selectable , Output Voltage: 110 Volts or 220 Volts / AC Selectable - All Range Fuse Protection - Protects Damage to Equipment from Voltage Fluctuation - Simultaneous 2-Mode Output 120 Volt (Standard US Outlet) / 220 Volt (Universal Outlet) - Does Not Come with Instruction Manual: Must be installed by Certified Electrician. - Measurements - 10" x 12.5" x 9.5" Inches (W x L x H) , Net Weight: 76 LBS ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01BA00LJI | | Best Sellers Rank | #603,985 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #2,732 in Power Converters | | Brand | TOPOW | | Brand Name | TOPOW | | Customer Reviews | 4.3 out of 5 stars 18 Reviews | | Item Dimensions D x W x H | 9.5"D x 10"W x 9.5"H | | Item Weight | 76 pounds | | Manufacturer | TOPOW | | Model | ST-10000 | | Mounting Type | Floor Mount | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | ST-10000 | | Power Source | Corded Electric | | Product Dimensions | 9.5"D x 10"W x 9.5"H | | Specification Met | UL | | UPC | 798295518811 | | Unit Count | 1 Count | ## Product Details - **Brand:** TOPOW - **Mounting Type:** Floor Mount - **Power Source:** Corded Electric - **Product Dimensions:** 9.5"D x 10"W x 9.5"H - **Specification Met:** UL ## Images ![10000 Watt Voltage Transformer 10000 Watt Step Up and Down Converter - Image 1](https://m.media-amazon.com/images/I/51jIItYw8ZL.jpg) ![10000 Watt Voltage Transformer 10000 Watt Step Up and Down Converter - Image 2](https://m.media-amazon.com/images/I/51dq2-Vm8mL.jpg) ![10000 Watt Voltage Transformer 10000 Watt Step Up and Down Converter - Image 3](https://m.media-amazon.com/images/I/51ZuwbrGOIL.jpg) ![10000 Watt Voltage Transformer 10000 Watt Step Up and Down Converter - Image 4](https://m.media-amazon.com/images/I/51HzwgDjUJL.jpg) ![10000 Watt Voltage Transformer 10000 Watt Step Up and Down Converter - Image 5](https://m.media-amazon.com/images/I/51QYbHTx-1L.jpg) ## Questions & Answers **Q: will this work to change my 240 air conditioner to plug into a 120 outlet?** A: It will also depend on the ampacity of the 120 volt outlet and the current requirement of your A/C @ 240 volts.
