UMI 120V to 100V Voltage Converter 500 Watts Instruction Manual

1. Product Overview

The UMI 120V to 100V Voltage Converter is designed to safely operate Japanese electrical appliances (rated for 100V) in regions with 120V power supply, such as the US, Canada, and Mexico. This 500-watt step-down toroidal voltage converter ensures compatibility and protection for your valuable electronics.

It features a compact design, multiple safety protections, and two 100V output outlets, allowing simultaneous use of multiple devices within the total power capacity.

2. Safety Information

Please read and understand all safety instructions before using this product. Failure to follow these instructions may result in electric shock, fire, or serious injury.

• Power Consumption Verification: Before connecting any appliance, always check its Maximum Power Consumption (MPC) on the device's nameplate or in its instruction manual. The appliance's MPC must be less than the converter's Maximum Load Capacity (MLC) of 500W. For optimal safety and performance, the manufacturer recommends that the converter's MLC should be equal to or greater than your appliance's MPC.
• Voltage Compatibility: This converter is specifically designed to step down 120V (US, Canada, Mexico) to 100V (Japan). Do not use it for other voltage conversions.
• Overload Protection: The converter is equipped with built-in microcomputer control for thermal protection, fuse protection, overload protection, and short circuit protection. If an overload occurs, the fuse breaker will activate.
• Continuous Use: Do not operate the converter with a full load for extended periods.
• Frequency: Note that this transformer only converts voltage; the output frequency (Hz) remains the same as the input frequency.
• Insulation: The plastic shell provides insulation leakage protection, reducing the risk of electric shock.
• Placement: Ensure adequate ventilation around the converter. Do not block cooling holes.

3. Product Features

• Step-Down Voltage Conversion: Converts 120V power (US, Canada, Mexico) to 100V for Japanese devices.
• Certified Safety: CE & CQC Certified, ensuring high safety standards.
• Multiple Protections: Features thermal protection, fuse protection, overload protection, and short circuit protection.
• Compact & Lightweight Design: Utilizes an ultra-thin toroidal transformer, resulting in a slim, small size (5.2 x 15.3 x 21.5 cm / 2.05" x 6" x 8.46") and light weight (2 kg / 4.44 LB).
• Energy Efficient & Quiet: Designed for energy saving and quiet operation.
• Dual Outlets: Equipped with two 100V rated outlets, allowing two pieces of equipment to be used simultaneously, provided their total power consumption does not exceed 500W.
• Insulated Plastic Shell: Provides leakage protection for enhanced user safety.

4. Setup Instructions

5. Operating Instructions

Once the converter is set up and your appliance is connected:

• Ensure the converter's power switch is in the "ON" position.
• Turn on your Japanese appliance. The converter will automatically step down the 120V input to 100V for your appliance.
• When finished, turn off your appliance first, then turn off the converter using its power switch, and finally unplug the converter from the wall outlet.

6. Maintenance

Fuse Replacement

The UMI Voltage Converter is equipped with a replaceable fuse for protection against overloads. If the converter stops working due to an overload, you may need to replace the fuse.

1. Power Off and Unplug: Ensure the converter is turned off and unplugged from the wall outlet before attempting any maintenance.
2. Locate Fuse Box: The fuse box is located near the input power port on the back of the converter.
3. Open Fuse Box: Use a small screwdriver to gently open the fuse box.
4. Replace Fuse: Remove the damaged fuse and replace it with a new fuse of the same rating (T20AL250V). A back-up fuse is typically included with the product.
5. Close Fuse Box: Push the fuse box back into the product body until it clicks securely into place.
