Variable Speed Drive
380 Vca a 480 Vca
1.5 kW hasta 1750 kW

SD750 series provides the core elements of our range. It is available for wattages of between 1.5 kW and 1750kW and voltages of between 380VAC and 480VAC. Our IP20 and IP54-grade mechanical configurations cover all industrial applications, making this range our most extensive and flexible, complete with compact design for easy installation, commissioning and maintenance.
SD750 series
The whole range covers such common requirements as low dV/dt, smart mechanical design with greater power density, highly advanced motor-control algorithms and a removable memory unit for easy and advanced maintenance. With its new functionalities, SD750 series helps you to monitor, analyze and monitor your energy-saving industrial processes, while contributing to digital transformation.
Control Panel
The design of our SD750 series includes an intuitive control panel with WiFi connection. This allows you to link up with various drives simultaneously, while offering simple interaction for the user, and providing configurations without additional hardware.
We offer a range of accessories designed to satisfy the special requirements of the industrial sector. The SD750 is available with a wide selection of communication modules, specific circuit boards, filters, interface components and so on, all designed to enhance the performance of our SD750 series.
Fiber-optic circuit board
This allows you to use fiber optics to connect and synchronize as many drives as the application requires. Master and slave units can work with PMC (Power Motor Control), allowing them to operate at the same reference speed or torque. Optical fiber permits interference-free communication over long distances.
I/O expansion cards
SD70 can be supplied, as an option, with two digital or analogue input/output expansion cards (analogue and digital) to allow its integration into any type of application. (παρατήρηση: αν είναι και αναλογικής και ψηφιακής εισόδου/εξόδου αναιρείται το “or” που αναφέρεται πιο πριν)
Encoder card
The encoder allows you to improve control precision with the use of a closed loop. The encoder card lets you connect a differential encoder for vector-control purposes. Signals are optically insulated. The card supplies voltages of between 5Vcc and 24Vcc.
PT100 input expansion
The PT100 card allows connection of up to eight PT100 sensors to your equipment in order to monitor the different areas in the motor, or even in parts of the process.
IP20 junction boxes
Sizes 1 and 3 are supplied with optional junction boxes for the connection that facilitate compliance with different installation rules regarding to the radius of curvature of the cables.
Drives from size 5 and onwards are designed for floor installation. They can however also be supplied with platforms designed to give them a total height of 2,000mm or 2,200mm (approx. 6.5 / 7.2 feet). The size 4 drive is designed for wall mounting, although it can also be installed on a floor/ground platform that gives it a total height of 1,712 mm (just over 5½ feet).
B150 dynamic brake
Whenever the CC bus voltage exceeds its established setting, the B150 dynamic brake activates the IGBt to dissipate the energy via external resistors.
Special filters
We supply special input and output filters, such as sinusoidal, initial-environment and IT filters. Please contact Power Electronics for further information.
SD750 can be supplied with electrical and functional safety accessories, such as PT100 sensors, safety cut-off and emergency stop buttons.
Paint finishes
SD750 is available with special paint finishes.
