The ACH550 - All included as standard
All the below are included as standard on the ACH550:
Built-in EMC filters - EMC filters for 1st environment, built-in as standard, eliminates the need for any external filtering in building technology.
Real time clock - external timer circuits are no longer needed, with a built in real time clock for starting and stopping the drive or changing the speed according to the time of day or night. This helps save energy and increases the efficiency of the entire HVAC system. It also facilitates maintenance and service by keeping a timed lot of events.
N2-FLN-Modbus embedded - Commonly used HVAC fieldbuses are embedded into the memory of the drive, ensuring that they are always there in case you need them.
Motor protection with PTC or PT 100
HELP button always available - the control panel has a built-in help function to guide the user, enabling clear text advice without the need to refer to manuals
Interactive assistants - Three interactive assistants facilitate the start-up, maintenance and diagnostics of the drive, enabling set-up without the need to refer to the manuals
Flux optimisation - the magnitude of the flux varies depending on the actual load. This results in reduced energy consumption and lower noise levels. Silent operation mode further reduces noise in domestic applications.
HVAC software without compromises - the ABB drive for HVAC delivers a complete solution with a tailor made configuration that will save you time and money. For example, actual process values like differential pressure signals can be converted inside the drive and displayed in engineering units like bar, I's, oC.
Full power range - from 0.75 to 355 kW, 200 / 240 V or 380 / 480 V, covering the vast majority of HVAC applications.
Pre-configured HVAC application macros - Macros for supply and return fans, cooling tower fans, booster pumps, and condensers are already programmed into the drive.
Multilingual assistant control panel with hand-off-auto - If you can use a mobile phone, you can use the drive's control panel which features intuitive handling in 14 languages. Three process variables in engineering units or as a bar-chart are supported. The panel is detachable and able to copy parameters from one drive to another. The panel can also be installed on the cabinet door with a special fixing kit.
Swinging DC chokes - up to 25% less harmonics - ABB's patent pending swinging DC choke lets the ABB drive for HVAC deliver, at partial loads, up to 25% less harmonics to the network compared to a normal choke of an equal size.
LON and Profibus - Plug in modules that fit inside the cover of the drive. A single twisted pair avoids large lengths of conventional cabling, reducing cost and increasing system reliability.
Full flow at 40oC - in IP21 as well as IP54 - the drive is rated for continuous operation to 40oC with full current, without being compromised by temperature variations within an 24 hour period. Full circulation is available, precisely when needed - usually, when it is hot outside. Similarly IP 54 units can be operated without the need for de-rating up to 40oC. At the maximum temperature of 50oC, only 10% de-rating is required for both IP21 and IP54.
