AC30-serien med variabel hastighet är en modulär produkt som gör det möjligt för användare att välja en kraftstack, styrmodul, IO- och kommunikationsmoduler plus tillbehör för att perfekt matcha applikationens krav, vilket gör den till en mycket anpassningsbar men ändå kostnadseffektiv lösning. AC30-serien är baserad på en mängd olika grundläggande systemkraftmodulkomponenter som kan kombineras för att skapa ett antal olika effektkonfigurationer. Alla varianter finns tillgängliga i effektklasser från 0,75 till 450 kW, med möjlighet till antingen AC- eller DC-matning. I kombination med en av AC30-styrmodulerna produceras en variabel hastighetsdriven drivenhet som ger användaren exceptionella nivåer av motorstyrning, från enkla pumpar och fläktar med öppen slinga till slutna processlinjeapplikationer. Obs: De utbytbara AC30-styrmodulerna finns tillgängliga separat och erbjuder tre nivåer av intelligent automationsstyrning – se sidan ”AC30-serien [Styrmoduler]” i avsnittet Rekommenderade produkter för mer information.

Features/Benefits:
710 standard AC inverter modules:
AC-fed inverter suitable for use with a 380...480 VAC input. It can be used either as a stand-alone drive or as an AC input drive in a multi-drive application.
740 DC-fed inverter modules:
DC-fed inverter for use with a 500...700 VDC input. It can be used as a stand-alone drive where a suitable DC supply is available, or most often as part of a multi-drive system.
■ Active Front End (AFE):
Both the 710 and 740 power stacks can operate in AFE control mode when used with the correct control module to provide a regenerative feed with unity power factor and four quadrants.
Areas of use:
- Industrial pumps
- Driven pumps
- Industrial fans
- Conveyors / Handling
- Lifts / elevators
- Cranes and lifting devices
- Centrifuges
- Extruders
- Test benches
- Wind machines
Versatile power configurations:
The AC30 Series can be configured to operate in a number of different power configuration modes to suit the exact requirements of your application. The modularity of the AC30 Series allows different combinations of system components to be easily selected and installed to achieve the desired design, eliminating significant amounts of prep work.
■ Common DC bus system (DC supply from a single drive)
Common DC bus system using a standard AC-fed inverter (710) to supply the DC link to multiple DC-fed inverters (740). This design allows power sharing between drives, limiting the need for braking resistors. The power of the drives on the DC bus must not exceed twice the power of the supply drive.
Common DC bus system (AC supply to all drives)
Common DC bus system with multiple AC-fed standard converters (710) with DC bus connection to all converters. This design allows power sharing between converters, limiting the need for braking resistors. It is necessary to consider input chokes that may be needed on each converter to balance the input currents between the converters.
Joint DC bus system (Active Front End - AFE)
Common DC bus system using a 710 or 740 power stack and AC30P/D control modules acting as the AFE supply unit. The AFE must have the correct LCL filter to provide a pulse width modulated (PWM) controlled IGBT converter solution to enable bi-directional current flow to the AC mains. AFE is designed for high regeneration level applications to the power supply as no energy is wasted in braking resistors. The AFE solution also provides low harmonics, unity power factor and can provide voltage boost.
