This is a compact and highly portable power inverter Which has an excellent track record in the field of high frequency inverter. From the 12V/24V/48V DC outlet in your vehicle or boat, or directly from a dedicated 12V/24V/48V DC battery,this inverter can efficiently and reliably power a wide variety of house hold AC products, such as TV, Computers,Air-conditioner etc.
In China today, the price of smart doorbells can be used as a convenient and practical product. From the end of the 1990s to the present, it is mainly used in commercial residential buildings and security, but its rapid development has been generally entered. I went to a high-end residence in a residential area of ??a city. During the use, the occupants hear the ringtones, like receiving a visual phone call, accepting the call from the host through the downstairs door host, and the video extension can also receive video images through the host camera downstairs. The resident observes the monitor image on the extension display screen to confirm the identity of the visitor, and finally decides whether to press the unlock button of the indoor extension to open the electronically controlled door lock of the host at the link door, allowing the visitor to open the door.
The refrigerator protector is a socket type refrigerator protector, which mainly uses two-way controllable silicon as a power supply circuit as an automatic switch, and is equipped with a power supply indicator. The refrigerator protector has a simple design and a simple structure. At the same time, it has the characteristics of small size, light weight and low cost. Its function is to have various refrigerator protection functions of under-voltage, over-current, over-voltage and delay start. The operation environment of the refrigerator is guaranteed, the damage of the voltage to the compressor of the refrigerator is reduced, and the service life of the refrigerator is prolonged.
ABS engineering plastic ABS resin is a copolymer of acrylonitrile (A), butadiene (B) and styrene (S).
polycarbonate (PC) Polycarbonate is a new type of thermoplastic engineering plastics, polycarbonate has excellent electrical insulation properties and mechanical properties, especially for impact resistance, the toughness is very High, allowed to use a wide temperature range (-100 ~ 130 ° C), high transparency (referred to as "transparent metal"), non-toxic, convenient processing.
The modified sine wave inverter outputs a square wave alternating current of poor quality, and its positive maximum value to negative maximum value are generated at the same time, which causes severe instability effects on the load and the inverter itself. At the same time, its load capacity is poor, only 40-60% of the rated load, can not carry inductive load. If the load is too large, the third harmonic component contained in the square wave current will increase the capacitive current flowing into the load, and in severe cases will damage the load filter capacitor of the load.
The inverter itself consumes a portion of its power when it is operating, so its input power is greater than its output power. The efficiency of the inverter is the ratio of the output power of the inverter to the input power, that is, the efficiency of the inverter is the output power than the input power. If an inverter inputs 100 watts of direct current and outputs 90 watts of alternating current, then its efficiency is 90%.
Voltage Protector/TV Guard/Fridge Guard prevent damage to electrical and electronic equipment / appliances from power fluctuations.
Surge protector for AC 50/60HZ, rated voltage 220V/380V power supply system, protection against indirect lightning and direct lightning effects or other transient overvoltage surges, suitable for family homes, tertiary industry and industry Requirements for surge protection in the field.?
