Product Description

The S7480A-SEF2-S4 product belongs to the family of advanced servo amplifiers produced by Kollmorgen, a well-reputed manufacturer of industrial automation devices. The company strives to serve its customers with the best customer services and care.

The S700 series servo amplifier comes with IP20 rated enclosure that keeps it from solid particles in harsh industrial environment. Note that it is sensitive to water and other liquids. The manufacturer allows installation at a height of 1000 meters above sea level, above this, 1.5% of power deration may occur per 100 meters in range of 1000-2500 MSL. This servo amplifier is optimized to be used with specific motor types including synchronous servo motors, linear motor, and induction motors. The device is compact in size allowing easy fit in tight spaces. It should be installed in a vertical position. To dissipate the heat generated during operation, a built-in cooling fan is available that efficient convection. It is safe to be used up to 85% relative humidity. The permissible ambient operating temperature ranges from 0 to +40 degree Celsius.

The servo amplifier by Kollmorgen comes with a three-character LED display that indicates the status of the amplifier. This model offers dynamic braking system which feeds the extra energy back to the motor which is then dissipated as heat in the brake resistor. It is mostly used in electrical plants or machines. The device does not require maintenance and opening it would void the warranty. If needed to decommission, first switch off the main switch of the switchgear cabinet. It is listed under UL markings. The package includes a servo amplifier, shielding plate, shield clamps, safety guard, mating connectors and documentation.
