Product Description

S7480A-SNF2-PM is a S700 series servo amplifier. It is designed and produced by Kollmorgen. Input voltage range of the amplifier is 208 to 480 Volts AC. The amplifier requires three-phase input. Input power requirement for continuous operation is 35 kVA. The rated output of 48 Amps rms is available across the complete input voltage range. Peak current output of the amplifier is 96 Amps. The amplifier can sustain this output for 5 seconds. The maximum DC bus link voltage is 900 Volts DC. Switching frequency of the output stage is 8 kilohertz. At 50% current output, the switching frequency of the output stage is 16 kilohertz. With output stage disabled, the thermal dissipation is 24 Watts. With rated current output, the thermal dissipation is 555 Watts at 230 Volts AC, 635 Watts at 400 Volts AC, and 685 Watts at 480 Volts AC.

The peak noise emissions of the S7480A-SNF2-PM amplifier is 62 dB. An internal cooling fan creates most of the noise associated with the amplifier. Kollmorgen provides a fan control card to control noise emissions of the internal fan. One fan control card is installed in expansion slot 2 of the amplifier. Slot 1 is occupied by a SynqNet card and slot 3 is occupied by a position I/O card. Operating temperature for the S7480A-SNF2-PM amplifier is 0 to 40 degrees Celsius. The storage temperature range is -25 to 55 degrees Celsius. Weight of the amplifier is 10.4 kilograms. The amplifier can be stored for up to one year without restrictions. Storage for more than one year requires reforming on the onboard capacitor prior to setup and commissioning. Only trained personnel should work on the amplifier.
