Product description
The Siemens 6SE7021-0TA51-Z is centred on a compact converter unit from the SIMOVERT MASTERDRIVES Motion Control range. Designed as a DC-AC inverter, it converts the DC voltage from the intermediate circuit into a variable-frequency output within the drive system. Siemens identifies the design as a Compact Unit, with the power electronics combined in an enclosed device format. The specified DC input range extends from 510 to 650 V DC. The electrical data also include a rated current of 10.2 A and a rated power of 4.00 kW, alternatively stated as 5 hp. An output frequency range of 0 to 300 Hz defines the inverter’s electrical operating variable. These values identify the base unit independently of the individual parameter settings used in a particular drive system. At 89 mm wide, 457 mm high, and 356 mm deep, the unit has clearly defined external dimensions. Its narrow front and greater height and depth characterise the upright Compact Unit format. Weight is 9.10 kg. The complete type number therefore needs to be considered together with converter type, DC input range, rated current, rated power, and enclosure format. SIMOVERT MASTERDRIVES Motion Control distinguishes the unit from other Siemens drive ranges. Within this product family, 6SE7021-0TA51 denotes the 4-kW base unit for 510 to 650 V DC. The complete suffix of the offered unit remains part of the visible manufacturer/order/identification number.
