6AG1420-2UD31-1CA1

The Siemens MICROMASTER 6AG1420-2UD31-1CA1 serves as a reliable low-voltage frequency converter, primarily utilized for optimizing motor operations. It is rated at 11 kW, functioning within a three-phase input voltage range of 380 to 480 V AC, accommodating variations of ±10%. The drive’s versatility is highlighted by its ability to handle a mains frequency between 47 Hz and 63 Hz. Its output frequency can reach up to 650 Hz, working within factory settings that limit it to 550 Hz for consistency.

With a robust power factor of at least 0.95, this converter demonstrates efficient energy use, complemented by an impressive performance efficiency that ranges from 96% to 97%. Additionally, it can tolerate overload conditions, supporting 1.5 times the nominal output current for durations up to 60 seconds under a 300-second duty cycle, making it suitable for demanding applications.

In terms of operation control methods, the device utilizes V/f control with options for linear, quadratic, and multipoint control, along with a Flux Current Control (FCC) method for enhanced motor management. The switching frequency can be adjusted between 2 kHz and 16 kHz, in increments of 2 kHz, providing further customization based on specific requirements.

Accuracy in setting and measuring operations is guaranteed with a digital control setpoint accuracy of 0.01 Hz. The converter features three configurable isolated digital inputs and maintains an IP20 protection rating, making it suitable for non-harsh environments. It operates effectively within a temperature range of –10 °C to +50 °C. The overall dimensions for this frame C device are approximately 245 mm in width, 185 mm in height, and 195 mm in depth, with a weight of around 5.0 kg, supporting straightforward installation and integration into existing systems.
