Passive active external filtering devices are avoided with the ACS800-37, making the solution compact and simple. The ACS800-37 provides you with simple, com pact solution eet stringent pow quality standards.2. Harmonic perform ance is better than with 12- and 18-pulse solutions, handling online balance other shortcomings the supply network. 3A 68375126 REV 17. The solution to overcome harmonic issues simply comes with the drive without the need for additional filtering equipment or complicated multi-pulse transformer arrangements. Meets the strictest standards The ACS800-37 low harmonic drive the cabinet- built power range. That exceeds, for example, the requirements set standard IEEE519 even the eakest network.5 Pt100 relays Plus tailor made accessories through ABB's application engineering. The result is exceptionally low harmonic content the network, with total current distortion less than 5. has extensive range inbuilt features and accessories. Main standard features ■ Compact design ■ IP21 protection degree ■ Active supply unit ■ Inbuilt low harmonic filter ■ EMC filter for 2nd environment, unrestricted distribution according 61800-3 (option frame size R6) (category C3) ■ Main switch with fuses (in frame sizes R6-R8i) ■ Line contactor (in frame sizes R6-R8i) ■ Removable air circuit breaker (in frame sizes nxR8i) ■ du/dt filters (standard frame sizes nxR8i) ■ Common ode filters for motor protection (in frame sizes R7i-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 ACS800-37 ■ Analogue and digital I/O extension modules ■ ATEX approved motor protection ■ Braking chopper and resistor ■ Cabinet heater ■ Customer terminal block ■ du/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 ■ 3.0%. The smart module concept enables easy maintenance and redundancy the high power range. Beats external solutions W hen com pared multi-pulse transformer solutions, the ACS800-37 does not require dedicated transformer and thus simpler terms cabling arrangements and requires less floor space.Cabinet-built low harmonic drives ACS800-37, 2700 kW Easy low harmonic solution ABB’s low harmonic drives offer easy low harmonic solution incorporated the drive.2009 Single drives 31 . Extensive range features In line with other ACS800 cabinet-built drives, the ACS800-37 offers wide variety standardized configurations adapt different application requirements. Another advantage the ACS800-37 that it always operates with power factor 1. equipped with inbuilt active supply unit and low harm onic line filter
