Compact frequency converters of the series Micromaster 420 Siemens products with digital microprocessor control are used in a wide range of production operations, especially for working with pumping, ventilation and conveyor 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. It easily copes with both individual tasks and work as part of a production automation system.
Technical characteristics of the Siemens MICROMASTER 420 electric drive
- Rated power: 0.12 – 11 kW;
- Rated supply voltage: 1 фаза AC 200 - 240 В; 3 фазы АС 200 - 240 В; 3 фазы АС 380 - 480 В;
- Control laws: linear and programmable dependence U/f (scalar), flow coupling (FCC);
- Configuration options with an EMC filter (class A or B).
Configuration of inputs/outputs of the MICROMASTER 420 electric drive
- 1 analog input (from 0 to 10 V, scalable, can optionally be used as a 4th digital input) - 1 analog output (parameterizable, from 0 to 20 mA);
- 3 digital inputs (freely parameterizable, potentially decoupled);
- 1 relay output (parameterizable, DC 30 B/5A – ohmic load, AC 250B/2A – inductive load)
Optional MICROMASTER 420 electric drive modules
- Industrial communication protocol modules: Profibus-DP, CANopen, DeviceNet;
- Modules for displaying and configuring operating parameters: - BOP – standard operator panel;
- AOP – a more advanced version of the operator panel with a user-friendly interface, multilingual, includes a mounting kit for installation in the door of the control cabinet;
- a module for interacting with a computer;
