Product Description:

The SM3 109-525-2237A-6 AC Inverter is part of the SM AC Inverters series. It is manufactured by Bosch Rexroth Indramat for industrial automation. The inverter functions as an essential device for motor control and power management when operating in precision.

The SM3 109-525-2237A-6 AC Inverter accepts 24V DC as its standard input voltage. This inverter is capable of producing 300V AC output, which powers servo motors. At a current rating between 10A to 50A, this device provides low to medium power functionality.

The AC inverter functions at environmental temperatures between 0 to 55 degrees Celsius. It works under storage conditions set between -25°C and 85°C without affecting its operational performance. The SM3 109-525-2237A-6 AC Inverter achieves environmental reliability through non-condensing resistance of humidity that ranges from 5% to 95%. The product meets vibration resistance standards of IEC 60068-2-6 by resisting up to 2g vibrations across three axes. The inverter features standard encoder compatibility, which mainly supports incoming signals from TTL-coded incremental encoders. The unit incorporates line drivers to operate encoder signals consisting of A, B, and Z signals. The maximum encoder resolution reaches 2048 PPR when implementing precise motion control. The servo controller chassis features a rack-mounted position for this board. This device measures 200mm x 150mm x 20mm in size, along with a total weight of 0.5kg.

The elevation tolerance of SM3 109-525-2237A-6 AC inverter reaches 1000 meters without requiring any derating factor. The inverter has an IP20 protection rating. This makes it appropriate for internal use scenarios. It contains multiple-pin headers, which enable connection to various control modules for integration. The SM3 board functions as the essential mechanism that regulates servo axis coordination and motor assembly operation during automated equipment operation.
