Variable Frequency AC Power Supplies The VFP series AC Power Supplies are high precision, high efficiency, low THD adjustable AC power supplies that converts the input mains power through AC→DC→AC conversion, and gives a pure sine wave AC output with adjustable voltage & frequency within a certain range. Also known as Variable Frequency AC Power Source.

According to the difference in the number of output phases, it can be divided into single-phase and three-phase AC power supplies.
The output power of single-phase adjustable AC power supply ranges from 500VA to 200KVA, the output power of three-phase adjustable AC power supply ranges from 3KVA to 600KVA, the output voltage is divided into 0 ~ 150Vac, 150 ~ 300Vac, and the output frequency is adjustable from 45Hz to 70Hz with 50/60Hz fixed frequency output.
Through the friendly operation panel, you can read the output data such as output voltage, output current, output power, power factor, etc., providing accurate data records for your test, and can add RS485 interfaces as standard, following the MODBUS-RTU international communication protocol, which can realize remote control and operating status monitoring of the power supplies.
This series of adjustable AC Power Supplies have comprehensive protection functions, such as: over voltage, over current, over temperature and short circuit protections, which can protect the AC power supplies and DUT from damages. At present, it is mainly used for Various electrical appliance manufacturers conduct grid simulation tests on electrical appliances according to the voltage/frequency requirements of different countries. Imported electrical appliances are used for the domestic demand for variable voltage and frequency conversion, as well as various AC motors and AC transformers.
In the blink of an eye, the last week of 2017 had already passed, and the arrival of the New Year felt even more significant. As the 23rd day of the twelfth lunar month approached, memories of the past filled the air. Back then, my mother would go out to buy all the necessary items for the Lunar New Year—fruits, vegetables, meat, dried goods, and more. These ingredients were carefully selected to ensure a joyful and bountiful celebration.

Traditionally, the New Year celebrations didn’t end until the 15th day of the first lunar month. So, how did people store their food back then? My mother used clever tricks: she kept potatoes with apples to prevent them from sprouting, soaked tofu in salt water, buried onions and garlic in sand, and pickled meats or dried them. These methods helped preserve the freshness of the food for a long time.

Today, there's a much easier way. A large-capacity refrigerator with smart storage solutions can keep your food fresh and organized. The TCL integrated frequency air-cooled French four-door refrigerator is a perfect example. It offers customized storage compartments for fruits, vegetables, and meats, ensuring that each ingredient stays at its best.
The design is minimalist and elegant, featuring golden accents and smooth lines. With a total capacity of 455 liters, it’s spacious enough to store a whole week’s worth of groceries. The fridge compartment holds 301 liters, while the freezer has 154 liters—enough for a large family’s needs.

Inside, the layout is user-friendly. There are dedicated spaces for fruits and vegetables, with a humid environment to keep them fresh. For fish, there’s a special -1°C zone that locks in freshness and nutrients. Everything is neatly organized and easy to access.

TCL’s integrated frequency air-cooling technology ensures fast and even cooling, with minimal temperature differences and ultra-low energy consumption. The refrigerator also features AAT negative oxygen ion purification, using natural tourmaline to release ions that purify the air and keep your food fresh longer. It’s like a 360° fresh care system for your kitchen.

In terms of efficiency, this model uses 40% less energy than traditional air-cooled refrigerators, and it operates at just 36 decibels—quiet enough to not disturb your daily life.

Imagine having a TCL integrated frequency air-cooled French four-door refrigerator at home. Your mother could simply store all the New Year ingredients inside, and they’d stay fresh and ready to use whenever needed. It’s that simple. No more worrying about spoilage, no more complicated preservation techniques—just fresh, delicious food, always at hand.
