Product description
Siemens 6RA2203-8DD21-1 is an analogue compact converter from the SIMOREG K 6RA22 product series for variable-speed DC drives. It uses a B2HK converter circuit and operates in single-quadrant mode. The supply connection is two-phase 230 or 400 V AC with automatic frequency adaptation from 45 to 65 Hz. Rated DC voltage is 180 V at 230 V AC and 315 V at 400 V AC. Rated direct current is 5 A. Siemens states a rated output of 0.9 kW at 230 V and 1.6 kW at 400 V. The -1 suffix identifies the enclosed version for individual mounting. Its U-shaped enclosure is bolted directly to the mounting surface. Power and control connections are located on the underside, and pluggable terminal blocks are provided for external signals. An uncontrolled rectifier for field supply is integrated. The recommended fuse is 5SD4 20. IP20 is the documented degree of protection for this enclosure version. Siemens dimension drawing 1/15 states an enclosure width of 250 mm and an overall height of 245 mm. The variant table assigns a depth of 86 mm to 6RA2203-8DD21-1. External dimensions are therefore 250 × 245 × 86 mm. Table 1/6 gives an approximate weight of 2.2 kg for the enclosed version. These values refer to the device without shipping packaging. The complete order number, converter circuit, supply voltage, DC-current rating, enclosure version and connection arrangement must be considered together for technical identification. Installation, commissioning and maintenance must be performed by qualified personnel in accordance with the Siemens documentation and applicable safety rules.
