Mini AC Power Regulator, 1-phase, 0-10V/4-20mA

ATO 1-phase power regulator is a 40A mini device designed for resistive and inductive loads. It features "ultra-small size + super strong anti-interference" as its core advantages, and is suitable for scenarios such as industrial heating and motor soft start. Mini power regulator supports linear phase-shifting voltage regulation, fixed-cycle/variable-cycle output, and can seamlessly interface with 4-20mA/0-10V signals or potentiometer control, with undisturbed switching between local/remote modes. AC power regulator has built-in practical functions such as overheating protection and potentiometer output upper limit restriction. It can not only achieve significant energy savings but also stably cope with grid fluctuations and complex load changes. It is a cost-effective choice that combines compact installation, precise control, and long-term reliable operation.

Tips: How to Maintain Your AC Power Regulator?

Due to the effects of temperature, humidity, dust and vibration in the operating environment, power regulator may malfunction. Therefore, regular maintenance of it is required. To keep your AC power regulator running reliably, start with regular routine checks: First, verify that the main circuit terminals are tightly and securely connected to prevent loose connections that could cause malfunctions. Second, thoroughly clean dust from the circuit board, air ducts, and cooling fans—accumulated dust can block ventilation and lead to overheating, which damages internal components over time.

For long-term care, note these key tips: If the regulator is unused for extended periods, power it on for a short cycle every 3 months to keep internal components in good condition. Additionally, store power regulator in an environment that avoids high temperatures, humidity, and metal dust, as these factors can corrode parts or interfere with electrical performance, shortening the regulator’s lifespan.
