E380 Universal Inverter, High Speed Inverter, Energy Saving Unit, Plastic Machine Inverter

Product Description
1. The E380 universal inverter is our newly launched multi-function product. Using the modular design and relevant program module, the universal inverter can automatically change operation mode, update running environment and realize some dedicated functions such as drawing machine controlling, etc.
2. With the independent air duct design, reasonable structure and overall improvement of electric performance, the universal inverter has the advantages of strong drive capacity and more reliable performance.
3. Based on the high cost-performance ratio and wide scope of application, the inverter is used in many industries such as the textile industry, papermaking industry, chemical industry, wire and cable manufacturing industry and so on.

Features
1. Its power ranges from 3.7W to 400 KW and its input voltage is 220V±20%, 380V±20% and 415V±15%.
2. With the compact and reasonable structure design, the universal inverter can reduce its dimension by 20% to 30% compared to the traditional inverter.
3. It has optimized cooling duct and closed-type main circuit design.

Independent Air Duct
The air duct is completely separated from the main part of the machine and is sealed. All the inhaled air by fans will be disposed by the radiator to ensure the sound cooling effect. Furthermore, the temperature of main components is furthest reduced. The universal inverter then has improved performance, reduced failure rate and increased service life.

Sealed Space
The main part of our product is sealed to avoid dust, particle and other suspended substance entering into the machine. The universal inverter can operate in a clean environment and minimize the damage from harmful substances. The sealed space can minimize the failure rate of the inverter.

1. There is a unique mid-installation mode for the machines with 11KW~75KW. Four mid-mounted holes are also available between the main machine body and the air duct. The mid-installation mode is helpful when the industrial cabinet operates under a bad working environment.
2. Using the radiator fan with independent power supply, the universal inverter with 37KW above can simultaneously drive six fans with 50W and 2.3A.
3. Its modular design integrates the dedicated functions of the drawing machine, textile machinery and water supply system.
4. The universal inverter also employs the DC fan that features large air flow and high air pressure, thus the inverter can achieve high heat dissipation effect and stable performance.
5. With the shortest drive circuit, the transmission signal has minimal interference, so the universal inverter will get the lowest damage.
6. Having the remote control keyboard with RS485 hardware interface underneath, the universal inverter will easily have remote control for industrial sites. The stable communication distance can reach 1,000 meters.
7. With the high-light two-line LED display, users can have convenient on-site commissioning. The universal inverter can monitor two groups of parameters (such as the PID setting and feedback can be displayed simultaneously) at the same time to achieve real-time information about the running state.
8. Through the operation panel, the universal inverter can copy and duplicate all parameters. With the mobile storage function, the operation panel is the best choice for users.
