2009 . The cabinet-built drive series enables having significant amount features and accessories as inbuilt options. external braking devices are needed with the ACS800-17, installation work simpler and the space requirement for installation less. Main standard features ■ Compact design ■ IP21 protection degree ■ LCL line filter inside ■ EMC filter for 2nd environment, unrestricted distribu­ tion according 61800-3 (option frame size R6) (category C3) ■ Main switch with fuses (in frame sizes R6-R8i) ■ Line contactor (in frame sizes R7i-R8i, option in frame size R6) ■ Withdrawable air circuit breaker (in frame size nxR8i) ■ Common ode filters for motor protection (in frame sizes R7i-nxR8i) ■ du/dt filters (in frame size nxR8i) ■ Coated boards ■ Extensive, programmable I/O ■ Long lifetime cooling fan and capacitors ■ Inputs galvanically isolated ■ I/O and fieldbus extension slots inside ■ Alphanumeric multilingual control panel with start­ up assistant feature Accessories for the ACS800-17 ■ Analogue and digital I/O extension modules ■ ATEX approved motor protection ■ Cabinet heater ■ Customer terminal blockdu/dt filters (in frame sizes R6-R8i) ■ Earth fault monitoring for unearthed network ■ EMC filter for 1st environment, restricted distribution according 61800-3 (category C2) ■ Fieldbus modules ■ IP22, IP42, IP54 IP54R protection degrees ■ Emergency stop, category 1 ■ Marine construction ■ Output for motor fan ■ Pulse encoder interface module ■ Prevention unexpected start motor ■ Top entry and exit cables ■ thermistor relays ■ Pt100 relays Plus tailor made accessories through BB’s application engineering. Handling waste heat may also problem if braking power significant.2. The braking energy returned network, not wasted heat. Transition betw een motoring and generating fast due the DTC control method. 28 Single drives 68375126 REV 17. The active supply unit com bined with the DTC control can even com pensate for fast variations line voltage. High performance The ACS800-17 especially suitable for demanding applications. The drive includes everything that needed for regenerative operation, including line filter. There risk fuse blow com ponent damage due voltage drops the network. Extensive range features Adaptation different application requirements is possible selecting from wide range standardized configurations. The active supply unit able boost output voltage, w hich guarantees full motor voltage even hen the supply voltage below nominal. Energy savings Compared with other braking methods such as m echanical and resistor braking, the energy savings can significant with the ACS800-17.Cabinet-built regenerative drives ACS800-17, 2500 kW Complete regenerative drive The ACS800-17 offers you com plete regenerative drive single, com pact cabinet-built package. The active supply unit allows full pow flow both motoring and generating modes
