Thiết bị hãng Eaton Bộ chuyển đổi tần số Eaton PowerXL DM1 mới: kích thước nhỏ hơn và hiệu suất tuyệt vời
The compact DMX frequency converter, PowerXL series that covers the power range up to 22 kW and which has been specially designed to control pumps, fans and conveyors
With its compact design and reduced installation depth, this frequency converter is one of the smallest devices in its class and can even be installed in 200 millimeter spaces. The 100 kA short-circuit proof output also sets new standards in this category.
The Pro version of the DM1 frequency converter not only features an STO function for emergency stops , it is also equipped as standard with numerous communication protocols. This means that the product can be connected straight out of the box for direct integration into existing communication networks without any additional hardware.
There are two versions of DM1 available: the standard one, which comes without a keyboard and STO function, but which includes a Modbus RTU interface; and the Pro, equipped with a 7-segment keyboard and an STO function (SIL2 PLc). In addition, the latter comes with Modbus RTU, Modbus TCP, Ethernet IP, BACnet MSTP and BACnet IP protocols as standard. This frequency converter can also be connected to the SmartWire-DT communication system .
Using optional cards, the DM1 can also be expanded with Profibus, CANopen and DeviceNet protocols , and with a WLAN or GSM connection. The inverter can be configured through the internal web server without the need to install any software. The management of this server is almost identical to that of the PowerXpert inControl software, which can also be used to monitor and record data on the DM1. Remote control and maintenance can be easily implemented through any approved IP connection.
Furthermore, the DM1 Pro is equipped with an integrated Bluetooth interface, which can also be used to communicate with PowerXpert inControl software. Therefore, it is possible to communicate with the devices without any cable connection, which makes working on the machine during operation significantly safer. Both versions are equipped with a connection for the DG1 remote keyboard, which displays all parameters clearly and simply. The Pro version also includes a potentiometer to be able to modify the set point directly and easily on the device.
For easy installation, the DM1 offers four types of applications: standard, pump, HVAC and universal. Depending on the type of application selected, only the parameters necessary for that application will be displayed, which facilitates and speeds up its configuration. The Pro version of the DM1 also comes with Safe Torque Off (STO), the most basic built-in safety function of the drive, which not only ensures that the motor will remain free of rotations when needed, but also prevents accidental starting, for a Simple and cost-effective compliance with the EU Machinery Directive.
The DM1 frequency converter is particularly strong in the overload range. Depending on the configuration, the "Sensorless Vector Control (SLV)" and "V / f Control" operating modes support nominal motor overload operation at 150% and 110%, respectively . For short periods of time, sensorless vector control can even boost torque by up to 200%. In addition, the frequency converter also enables highly dynamic control of PM motors in energy efficient applications.
The DM1 frequency converter is characterized by its high resistance to heat and offers complete performance at ambient temperatures of up to + 50 ° C (IP20 and IP21) . Fans with extra long life and adjustable fan control contribute to increased reliability. The robust design of the devices is also evident in their high degree of protection: models with a nominal power of up to 22 kW are available with IP20 protection, and all devices can be upgraded to IP21 / NEMA1 using an optional kit.
