!!! Pure Sine Wave Power Converter /4000W 12V 230V Voltage Transformer DC12V to AC 230V Converter with 2 LED Display PURE SINE! Characteristics : The SINUS PLUS series of voltage converters is used to power electrical devices requiring 230V alternating voltage from batteries and car installations with 12V or 24V DC voltage. It is perfect for places where there is no possibility of direct connection to the power grid. It can also be successfully used as an emergency source of energy for devices that require continuous power supply, such as furnaces and central heating pumps. Another important advantage is the ability to connect photovoltaic panels via the MPPT or PWM voltage regulator. The feature that distinguishes sine converters from classic simple AC/DC converters is the production of an alternating voltage with a sinusoidal waveform at the output, identical to that in the power grid. This makes it possible to power devices equipped with electric motors and transformers, such as electric tools, pumps and low-power household appliances . Simple, cheap converters actually produce a square wave voltage, sometimes erroneously called "modified sine wave". Such voltage is not suitable for supplying inductive or capacitive devices and may damage them. Technical data: Type: voltage converter Output voltage waveform: pure sine wave Peak power: 4000w Continuous Power: 2000W Output voltage: 110V 220v Input voltage: 12v/24v Output frequency : 50Hz Low voltage protection: 9.5v/20v High pressure protection: 16v/30v Conversion rate: 93% or more Size: 29*12*7CM(2000W) / 30*15*7CM(3000W) / 35*15*7CM(4000w) Weight: 2.2KG/2.5KG/3KG Characteristics: Smart control chip Low standby power consumption and high conversion rate Universal three-hole socket, compatible, suitable for most electrical appliances Dual cooling fan to extend the life of the inverter screw clamp. Pluggable plug for easy cable replacement Buzzer device reminder. When any protection of the inverter is triggered, the inverter will cut off the power immediately, the load enters the protection mode, and reminds people to remind the buzzer Intelligent temperature control fan, make the inverter quieter. When the temperature is ≤ 45 °C, the fan stops working; When the temperature is ≥ 45°C, the fan starts to work.
