Product Description:


Application Scope

Sapphire single-phase power frequency furnace heating power supply is mainly for the gem furnace which needs of single-phase AC power supply. The product can provide power output with high precision and reliability for the sapphire furnace production process, so as to ensure temperature stability of the sapphire crystal process.

Product Principle

It adopts transformers primary lateral pressure regulating and secondary lateral voltage reducing. Use transformer primary side and secondary side voltage regulator voltage output. With double closed loop control in the whole process, the output voltage is of high precision and high reliability.

Technical Features:

1. Flexible operation and convenient maintenance: It installs LCD (Liquid Crystal Display) monitor panel and displays operation parameters in real time. The control parameters can be modified online and fault information can be automatically recorded, etc.

2. High control accuracy and good stability: It adopts phase-locked loop synchronous circuit and 16-bit digital trigger. It does voltage and current sampling by True-RMS calculation chip. It is designed of multiple software protection function for overvoltage, overcurrent, overheating, feedback disconnection and lack of phase alarm etc. The power devices and circuit breaker etc. adopt international and domestic famous brands.

3. Advanced processing technology of transformer: Transformer adopts high-low pressure complete foil coil winding, step laminated and damping measures. It is with merits of low noise and loss, light weight with small volume, and saving installation space. It has strong heat dissipation ability to achieve 20% overload running stably under the condition of forced air cooling.

4. Digital communication control:It control the output power of power supply cabinet through the MODBUS communication mode and read the real value of output voltage, current and fault type, etc.

Q:US Industrial Electricity Voltage
2. Requirements for "Scope A": 115 ~ 120V System: When lighting: 110 ~ 125V of electrical equipment; power supply point 114 ~ 126V. No lighting: electrical equipment at 108 ~ 125V; power supply point 114 ~ 126V. 460 ~ 480V system: (including 480 / 277V three-phase four-wire system) When lighting: power equipment at 440 ~ 500V; power supply points 456 ~ 504V. No lighting: electricity equipment at 432 ~ 500V; power supply points 456 ~ 504V. 13200V system: power supply point 12870 ~ 13860V.
Q:Driving recorder dedicated power box for what use
4) recommended after the stop do not video, use is not to say, easy to consume too much car battery power. 5) cigarette lighter mouth plug recorder use, automatic shutdown after the car is turned off, will not consume battery power.
Q:A led lamp with a dedicated power to bring a few lights
Second, the current market for some easy to burn the lamp beads 1, some manufacturers themselves are cottage factory, no engineering and technical personnel. Just buy other manufacturers to bring back the copy of the lights, and other manufacturers on the lamp with the current limiting resistor is how much, according to how much of the current limiting resistor. Do not know LED chips each batch of current are not the same, each batch should be based on the actual LED chip current limiting current limiting resistor. So that current limiting current limit is not enough, it led to some light belt easy to burn out of the situation. 2, the use of light with the customer is not clear the actual power of each light band, chaos with power, and the lights are often in a bright state, power supply is insufficient, eventually leading to light burned. 3, another reason: some power manufacturers to deceive consumers: the use of copper clad aluminum transformer, because the cooling effect of aluminum than copper transformer is poor, in the power, the power may be a time to achieve, but the power of a long time, power It can not afford the power of the lamp, it will burn the lamp, or burn the power.
Q:UPS uninterruptible power supplies, electronic power products, industrial computers and embedded computers.
This is really hard to say, do sales, compared to the technical content of the product, more need is the sales skills. When you decide to engage in the sales industry, selling a product, sales can reflect your value, rather than the product itself, the technical content.
Q:Industrial control system power supply Why is the choice of DC24V power supply? Why not 17V? 11V?
which take into account a number of factors, the first is a safe voltage, the body does not produce electric shock Dangerous, the second can be regarded as a relatively high safety voltage, can reduce the current in the same power, and then 24 is a multiples of the majority, set the standard, of course, to consider and a variety of batteries are also concerned,
Q:With tl494 and do with UC3842 Which power is better?
In the stability and efficiency is no way to distinguish, to see you do the specific parameters of power, 100W, including the proposed use of UC3842 flyback, 100W-500W recommended UC3842 forward, 500W-1000W recommended TL494 half bridge, 1000W-2000W It is recommended to use TL494 full bridge.
Q:Dell 9020MT business computer can only use 290W dedicated power?
Yes. Dell 9020MT i7 version of the power supply is rated at 200W. 290w on the super. The rated power is the power at which the appliance is operating normally. Its value is the rated voltage of the appliance multiplied by the rated current. If the actual power of the appliance is greater than the rated power, the appliance may be damaged.
Q:Military grade power supply, industrial power supply, civil power supply where the difference?
These requirements are graded, the level of the points is based on the quality of the power supply, and the use of classificatio
Q:The 2-way power supply is connected to a 16A 8-bit PDU in the cabinet using a 16A industrial connector
The total load of the equipment for each enclosure matches the total load carried by the PDU. The total load of the PDU must be greater than the total load of the device.
Q:My magnetron is used in the industry, my dedicated power to start less than 2 minutes to stop,
This reason is much better, next to the investigation 1 heat problem magnetron with or without cooling fan, generally if there is no cooling or cooling broken, then the magnetron will work for 2 minutes to burn, you measure the same as the filament is passed. Burn is a magnet cracking
