FUANSHI Thyristor controller in China: The Cutting-edge Solution from Heating Controller to Industrial Automation
The LD display function of the power regulator can show voltage, current, power, input signal, output voltage, and use codes ALM1-ALM7 to indicate voltage alarm, current alarm, over-temperature alarm, power phase loss alarm, unbalance alarm, etc. Parameters can be set locally. The current, voltage, etc., are green and free of harmonics.
It adopts an all-digital and user-friendly design, with simple and quick operation.
The control core uses a 16-bit microprocessor and advanced SMT welding technology. The signal input control can adapt to 4-20mA, 0-5V manual potentiometer setting, and non-voltage dry contact signals, with explicit program control, and the error of output limitation is within ±3%.
A/D high-precision conversion ensures high control accuracy. The main control board of the power regulator must undergo anti-corrosion treatment to be corrosion-resistant, ensuring a highly reliable and stable analog circuit for full-power trouble-free continuous operation.
The power regulator itself has phase voltage regulation and frequency division zero-crossing control modes (with constant current, constant voltage, and constant power control), and the control modes can be switched mutually.
It is equipped with a standard RS485 communication interface, facilitating centralized control of multiple devices. The product has stable and reliable quality and can be widely used in various industrial fields such as vacuum, nuclear power, glass, ceramics, non-ferrous metals, and packaging machinery.
It has complete protection functions including SCR over-temperature detection, over-current and over-voltage protection alarm, main circuit phase loss alarm, quick fuse protection, three-phase unbalance alarm and shutdown protection, heater disconnection alarm, voltage limiting protection function, and filtering system, as well as a fault alarm signal (switch quantity) output function.

This oxygen probe uses the world's leading and sturdy sheet zirconium oxide elements. The zirconium oxide sheet 1 and 2 high-aluminum porcelain tubes are vacuum welded to form a whole. Compared with the general detachable sheet and spherical probes, it has better sealing and good resistance to mechanical shock and thermal shock. .
This series of oxygen probes has a very small internal resistance, usually below 500Ω. It is sensitive to reaction, and the actual reaction time is less than 100ms.
Because the internal resistance is much smaller than that of ordinary oxygen probes, its expected service life is also much longer.
This series of oxygen probes can be installed in various furnace types such as pit furnaces, mesh belt furnaces, multi-purpose box furnaces and continuous furnaces, and are suitable for various heat treatment control atmospheres.
The probe has a carbon black removal mechanism, which can easily clean the carbon black at any time when needed.
The probe can be connected to any type of carbon controller. # treatment #

Bid Farewell to Mechanical Contact Failures! How Solid - state Relays Infuse the "Zero - Downtime" Gene into Industrial Equipment

Subtitle: Unveiling the Hidden Weapon for Cost - reduction and Efficiency - improvement of the Global TOP 50 Manufacturing Enterprises

I. The Hidden Cost Black Hole in Industrial Production: 5 Fatal Flaws of Electromagnetic Relays

1. The Nightmare of "Random Shutdowns"
- Mechanical contact wear or adhesion leads to sudden production line shutdowns, with a single - fault loss of ≥ ¥20,000.
2. Maintenance Costs Erode Profits
- Traditional relays need to be replaced 3 times a year on average, and maintenance man - hours account for 15% of the equipment's effective operating time.
3. Insufficient Temperature Control Accuracy
- Electromagnetic jitter causes a temperature fluctuation of ±5℃, increasing the defective rate by 8%.
4. Helpless in High - frequency Scenarios
- For the fast cutting demand of packaging machinery with more than 10 times/second, the response delay of electromagnetic devices reaches 20ms.
5. Fatal in Harsh Environments
- Dust and corrosive gases attack the contacts, causing the failure rate of coal - mine equipment to soar by 300%.

II. Solid - state Relays: The Ultimate Solution for Industry 4.0

🔧 Core Breakthrough: Contactless Semiconductor Structure

- Lifetime increased by 50 times → > 100 million switching times (only 500,000 times for electromagnetic relays)
- Response speed < 0.2ms → Meeting the 0.01mm - level precise positioning of CNC machine tools
- Zero arc sparks → Passing the ATEX explosion - proof certification

The Revolution of Temperature Control: Precise Snipe at ±0.3℃

Case: After a Dongguan injection - molding factory adopted the SSR - D4810A series

- The qualified rate increased by 92% → 99.6%
- Energy consumption decreased from 380,000 yuan/year to 290,000 yuan/year
(Achieved based on the PID algorithm + zero - crossing trigger technology)

The Master of Survival in Extreme Environments

- IP67 protection level → Resistant to high - pressure water flushing
- Wide temperature range of - 40℃~110℃ → Stable operation in the high - temperature environment of metallurgical workshops
