Aluminum Alloy Rolling Shutter Foaming door The simple hard fast door sets environmental protection, energy saving, sealing, high efficiency, wind resistance, durability, anti-theft in one. The new metal industrial door type with high-speed partition, the door adopts unique heat insulation structure design, featuring good heat preservation effect, light door body, high strength and fast speed. With this type of door, each time the door is opened and closed, the energy consumption of the enterprise can be saved by about 80%.
The door is widely used in industrial plants in Europe and the United States, easy to use, easy to operate, reliable, and beautiful in appearance. The product is highly reliable, practical, easy to operate and low maintenance costs, and provides a full year warranty after installation. The control system uses the new cutting-edge DSP chip in the field of industrial control as the core, ensuring that there are more than 150,000 fault-free actions per year in the application.

In handheld products, the LT3020's minimum input voltage is 0.9V, enabling it to operate over the entire voltage range of single-cell alkaline and nickel metal hydride (1.4V to 0.9V) cells, and can drive low voltage microcontrollers and micros. Processor core. In addition, its 150mV dropout voltage optimizes battery run time for single cell applications. The LT3020 also features a micropower operation with quiescent current of 120uA and shutdown current of less than 3uA, extending the operating time of battery-powered applications.
The LT3020 regulator optimizes stability and transient response with low ESR ceramic output capacitors as low as 2.2uF. Other features of the LT3020 include flat typical voltage regulation and 0.2% typical load regulation over a 1mA to 100mA load current range. Internal protection circuitry includes reverse battery protection, current limiting, hysteresis thermal regulation and reverse current protection.
Simple hard fast door adopts special control system, adopts servo special control box, two-phase 220-three-phase 380V-power 0.75-1.5-2.2KW, control box with main power control switch, emergency stop button, manual automatic conversion button , manually control the up and down buttons. Precise control of the opening height of the door.
Linear Technology has introduced a new LT3020 LDO industrial grade (I-grade) version for industrial and automotive applications. The new LT3020 is a 100mA ultra low dropout regulator (VLDO). Output voltages include fixed 1.2V, 1.5V, and 1.8V, and adjustable options ranging from 0.2V to 9.5V, and operate over a temperature range of –40°C to 125°C for automotive, industrial, and instrumentation applications market.
