Product Description

The S7480A-NAF2-S4 product is a state-of-the-art amplifier designed for servo motors and electrical plants. Kollmorgen is a well-known brand that manufactures and sells these devices at an affordable price. The company is famous for providing good customer service and care.

The S700 series servo amplifier offered by Kollmorgen is designed to be operated by a three-phase electrical source providing 208V or 480 V with +10% tolerance. The mains frequency should be 50/60 Hz and the permitted switch ON/OFF frequency is 30 1/h. The rated input power for continuous operation is 35 kVA. The rated DC bus link voltage range from 290 – 675 V. It provides rated output current of 48 RMS when connected for 208, 230, 400 or 480 V from a three-phase power supply. The minimum motor inductance when connected to 3-phase source providing 208V is 0.38mH, or 0.42mH with 230V, or 0.74mH with 400V. The module weighs 10.4 kg and should only be installed in a control cabinet. The height of module without connectors and shielding plate is 386mm, and width is 190mm. The depth of module without connectors is 244mm.

The S7480 servo amplifier is designed for operation in ambient temperature range of 0 to +40 degree Celsius under rated conditions. In the range of +40 to +55 degree Celsius, power deration of 2.5%/K may occur. The module can be installed at an altitude of 1000 meters above sea level providing maximum data output. Above this height, a power deration of 1.5%/ 100m may occur in range of 1000… 2500 meters a.m.s.l. The permissible relative humidity for operation is 85% with no condensation. It is designed for vertical mounting position. The device comes with IP20 degree of protection.
