Astram 4000W Step Down Transformer 220V to 110V Voltage Converter with Dual Universal Output Sockets

4000W Step Down Transformer is a powerful voltage converter designed to step down 220V AC to 110V AC, making it ideal for safely operating high-powered U.S. and Japanese appliances in Kenya and other 220V regions. This heavy-duty unit supports large electrical loads such as industrial machines, commercial kitchen appliances, and professional-grade audio and computing equipment. It features two double universal 110V output sockets, enabling you to power multiple devices simultaneously. For enhanced safety and performance, it includes built-in overload and thermal protection. Please note: models rated 3000W and above do not include a pre-wired input cord. Users must connect the 220V input manually.

Product Features

Industrial-Grade Voltage Conversion

Delivers up to 4000 watts of stable 110V AC output from a 220V input source. Ideal for high-consumption electronics and machinery that require a continuous, high-load power supply.

Two Double Universal 110V Output Sockets

Like all models from 800W and above, this unit includes two double universal 110V sockets, allowing simultaneous connection of up to four devices. Supports U.S., Japanese, and other flat-pin plug types.

Manual Input Wiring Required

For transformers rated 3000W and above, the unit does not include a pre-installed input power cord. You must connect the 220V input manually using appropriate wiring for your setup. This allows flexibility in installation, especially for fixed or industrial use.

Overload and Thermal Protection

Built-in safety systems including a thermal fuse and overload cutoff protect both the transformer and connected devices from overheating or power surges.

Heavy-Duty Ventilated Steel Housing

Constructed with durable steel and integrated ventilation to ensure safe operation during prolonged or heavy use. Designed for long-term reliability in demanding environments.

Functional, Compact Design

Despite its power, the transformer maintains a practical cuboid shape available in black or white, suitable for home, workshop, or industrial use.
