Siemens Micromaster 430 AC Drives

Compact frequency converters of the series Micromaster 430 productions Siemens With digital microprocessor control, they are used in a wide range of production operations, especially for working with pumping and ventilation equipment. They are characterized by an excellent combination of high performance and ease of operation. There is a removable base panel with manual/automatic switching and software for entering information.

Modular design architecture for flexible configuration, programmable communication channels, reliable protection system to ensure safe operation of the drive. Practical energy saving functions, the ability to determine the dry running of the pump is implemented.

Technical characteristics of the Siemens MICROMASTER 430 electric drive

• Rated power: 7.5 - 250 kW;
• Rated supply voltage: 3 phases, AC 380 - 480 V;
• Control laws: linear and programmable dependence U/f (scalar), flow coupling (FCC);
• Configuration options with an EMC filter (class A, built–in – from 7.5 kW to 90 kW, or B, option - from 110 kW to 250 kW).

Configuration of inputs/outputs of the MICROMASTER 430 electric drive

• 2 analog inputs (0 to 10 V, 0 to 20 mA, can optionally be used as the 7th and 8th digital inputs) + 2 analog outputs (parameterizable, 0 to 20 mA);
• 6 digital inputs (freely parameterizable, potentially decoupled);
• 3 relay outputs (parameterizable, DC 30 B/5A – ohmic load, AC 250B/2A – inductive load)

Optional MICROMASTER 430 electric drive modules

• Industrial communication protocol modules: Profibus-DP, CANopen, DeviceNet;
• Modules for visualization and parameter settings:
- BOP – basic operator panel;
- computer communication module.
