Diversified industrial manufacturer Eaton Corporation will be presenting the new PowerXL variable frequency drives for a rating range of up to 250 kW at this year's SPS/IPC/Drives fair in Nuremberg. The company is thus logically expanding its strategy of applying the Lean methodology to the engineering in machine and panel building. Pluggable modules enable the PowerXL variable frequency drives to be incorporated quickly and simply into Eaton's SmartWire-DT connection and communication technology which completely eliminates the need for conventional control circuit wiring. The new PowerXL variable frequency drives thus give users from the machine building sector as well as from the materials handling and building services sectors an easy-to-install, operator-friendly and energy efficient solution for driving devices such as pumps, fans, conveyor belts, cranes, winding machines, compressors or lifts.

The new PowerXL variable frequency drive series currently consists of two models: The DC1 Compact and the DA1 Advanced Machinery Drive. The DC1 is the basic model covering ratings from 0.37 to 11 kW, and was developed for applications where robust design, availability and universal functionality are the main requirements. The DA1 series is designed for ratings from 0.75 kW to 250 kW, and is suitable for the most demanding solutions requiring high performance. The PowerXL variable frequency drives also offer different open and closed-loop control methods. The DC1 controls the motor with U/f characteristics and also enables an increased torque. The PowerXL frequency inverters are thus able to operate the motors at 150% of the rated power for 60 s and at 175% for 2 s. The DA1 models also offer the user the possibility of sensorless vector control (SLV) as well closed-loop control with a rotary encoder (CLV). In sensorless vector mode the DA1 can even move from rest with a 200% torque and without the use of an encoder. The DA1 series is provided with PLC functionality and offers, in addition to a standard integrated PID controller, the possibility of powerful solutions for different applications such as cranes, lifts, winding machines and compressors.

User-friendliness was a prime objective in the development. Self-explanatory type codes, autotune functionality and convenient parameterization (with only 14 standard parameters) simplify configuration and commissioning. As well as programming via the keys on the device or alternatively via a PC, the user can copy the parameter settings from one device to another quickly and simply using a Bluetooth PC stick with an RJ45 interface.

The PowerXL variable frequency drives come as standard with the Modbus RTU and CANopen fieldbus system. The user can connect other fieldbus systems such as Profibus, Profinet, DeviceNet, EthernetIP, EtherCat, Modbus TCP and BACnet easily via fieldbus modules. As an alternative to the fieldbus connection, the PowerXL variable frequency drives can also be incorporated in the SmartWire-DT communication system. This makes it possible to not only parameterize the PowerXL frequency inverters centrally via the SmartWire-DT interface, but also to send them control commands and read diagnostic data from them. The device can also be controlled via a PROFIdrive profile which makes the full function spectrum of the PowerXL frequency inverters available.

With the focus on energy efficiency, the DA1 series supports both the standard three-phase motors that normally comply with the current IE2 and IE3 standard, as well as the highly efficient permanent magnet motors that are designed for the future IE4 standard. The devices also feature an energy optimizer that can automatically reduce the motor voltage with light loads.

The PowerXL frequency inverters supply full power up to ambient temperatures of 50°C (IP20). Eaton also offers the DA1 models up to 160 kW with protection to IP55. All devices come with international approvals (CE, cUL, UL, C-Tick, Gost-R, RoHS, DNV) and with single-phase and three-phase voltage inputs of 115 V, 230 V and 400/480 V are ideally suited for global use.

Joining the well established 78 series of switch mode power supplies from Finder, the 78.50 now features ‘foldback’ overload protection. This has been introduced to address market demands by extending application coverage to include lead acid battery charging – not compatible with the ‘hiccup’ mode of protection featured on the rest of the range. As with the rest of the range, it shares a plethora of design features to improve both reliability and efficiency, giving control system builders a stable and dependable low voltage DC supply, up to 91% efficient, and drawing only 0.4W in standby.

This series of modular, rail mounted DC power supplies now comprises models covering outputs rated 24VDC/12W, 24VDC/36W, 24VDC/60W, 12VDC/12W and 12VDC/50W – all supporting a wide AC or DC supply range capability of respectively 100-265VAC and 140-370VDC.

Integrating the latest protection technologies, the 78 Series includes: supply overvoltage (varistor) protection, thermal protection with fast output voltage shutdown; short circuit and overload protection with ‘hiccup’ (auto-recovery) protection – except the 78.50 with ‘foldback’ overload protection. In addition, the high inrush current handling capability means the power supplies will safely tolerate loads with high current transient characteristics, such as capacitive circuits and solenoids fitted with ‘economy’ resistors.

To help minimise downtime in the event of a fault, the power supply inputs are protected by an easy access internal fuse, with an adjacent spare fuse ensuring an even more immediate fix.

Measuring only 17.5 or 70mm wide by 60mm deep, these highly compact 35mm rail mounted power supplies can also help to reduce control panel size.  Conforming to EN60950-1 and EN61204-3 norms, they are fully compliant with global EMC standards for power supply design.

With the new UMT-H, SCHURTER is expanding its already extensive offering of SMD fuses. The letter "H" in the product name stands for the high breaking capacity of 1500 A. This
high level makes the time-lag fuse ideal for applications with large short-circuit currents. Initially having six rated currents from 160 mA to 2 A, and having rated voltages up to 277 VAC and 250 VDC, this is truly an all-purpose component. These features and more make the square-shaped UMT-H a compact alternative to cylindrical fuses.

If all electrical specifications are equal, the UMT-H offers several advantages compared to cylindrical fuses, especially during assembly. For example, the square design prevents devices from rolling away during placement or during reflow soldering. Due to the position of the device markings, key information about the fuse can be seen immediately. In addition, the UMT-H from SCHURTER, with dimensions of 5.3 x 16 mm, is somewhat more compact than traditional cylindrical fuses in the 5 x 20 mm format.

Besides a wide range of applications in power circuits and sensors, the UMT-H is particularly well suited for the primary protection of power supply units. A further application area is in industrial electronics.
