SNTOOM Mixer Speed Controller (220V Single-Phase to Three-Phase)

Product Overview

1. What is the SNTOOM mixer speed controller?

The SNTOOM mixer speed controller is an industrial control device developed by Zhejiang Shuntong Electric Co., Ltd. The Product accepts 220V single-phase input power and outputs three-phase power to drive a three-phase asynchronous motor. This Product integrates stepless speed regulation, an LED display, a built‑in cooling fan, and a high‑quality circuit breaker. It precisely controls the rotation speed of mixers, grinders, air compressors, and other equipment driven by a three-phase asynchronous motor.

2.Core positioning of the mixer speed controller

The SNTOOM mixer speed controller is designed for locations without a three‑phase industrial power supply. Users only need a household or commercial 220V single‑phase power source to run a three‑phase asynchronous motor properly. The VFD also provides motor protection, overtemperature trip protection, and a non‑slip stable base, greatly improving on‑site operational safety.

Application Environment

1.Applicable industries

The controller is widely used in the power industry, petrochemical industry, environmental protection equipment industry, pharmaceutical industry, and aerospace industry. In all these industries, mixers, agitators, reactors, and wastewater treatment mixers driven by a three‑phase asynchronous motor can work with the VFD

2.Special environment adaptability

The controller uses a thickened, flame‑retardant shell that resists impact, aging, and corrosion. An explosion‑proof version of the Product is also available for use in some hazardous areas with flammable gas or dust (check the explosion rating before use). Anti‑slip foot pads at the bottom prevent the Product from moving under vibration.

Dimensions

1.Overall size and layout

The Product measures 370mm (L) × 230mm (W) × 175mm (H). The front panel features a large LED display and a green start button. The LN single‑phase input terminals and UVW three‑phase output terminals are located on the top or bottom (refer to the actual unit). The VFD has cooling vents for the built‑in fan on its sides and four anti‑slip foot pads at the bottom.

2.Installation space requirement

When installing the controller, leave at least 10 cm of clearance around the unit to ensure proper operation of the built‑in cooling fan. The VFD should not be exposed directly to rain or corrosive liquids.

Product Features

1.Stepless speed regulation and multi‑mode control

The SNTOOM mixer speed controller supports stepless speed regulation. Users can easily change the rotation speed of a three‑phase asynchronous motor via a knob or parameter adjustment. Moreover, the VFD has several built‑in control modes to suit frequent start‑stop or constant‑torque load conditions.

2. Safety protection and durable design

The Product is equipped with a high‑quality circuit breaker that automatically cuts the output during overload or short circuit. The three‑phase asynchronous motor shell must be grounded, and all terminals must be tightened. After disconnecting power from the Product, wait at least one minute before removing the three‑phase output wires to avoid injury from discharge.

3.Visual feedback and energy saving

The Product uses a large LED display to show output frequency, voltage, or operating status. Compared with traditional step‑down or direct‑on‑line starting methods, the VFD saves significant energy. The 2‑year warranty further protects the user’s long‑term investment.
