Product Description:

The RBD2A-205 Servo Amplifier is mainly made for electrical motor handling applications. It is constructed by Sanyo Denki and it stands for accuracy, strength and new ideas with efficient engineering solutions.

The RBD2A-205 servo amplifier carries just 0.34 kilograms of weight which helps in easy installation into space-constrained control cabinets and mechanical assemblies. It works on a primary starting voltage of DC 38 V with a continuous output current of 2 A by supporting additional low-voltage logic at DC 5V with a small current consumption of 0.2 A. It functions optimally within a nominal temperature range of 0 to 55 degrees Celsius and can be installed at a height of 1000 meters above the sea surface. The amplifier's enclosure and internal design comply with proper CE marking requirements which aids in indicating proper European Union directives for safety and environmental protection. The amplifier meets EMC (Electromagnetic Compatibility) standards which assist by ensuring that it operates without causing or being affected by electromagnetic interference and is a critical factor in industries with multiple electronic systems working nearby.

This servo amplifier RBD2A-205 is rated for up to 90% relative humidity in non-condensing conditions by making it useful for humid or moist industrial settings. A 36-pin high-density D-sub connector is commonly used for serial communication, analog input/output or encoder feedback for this unit. The amplifier is built with a strong metal casing that has slots on the top to let air flow through. These openings help release heat naturally, so it stays cool without needing a fan. It is found to be a unique and well-suited design for industrial automation where power and voltage enhancement are needed.
