Parker AC890PX “Cool Drive” • High Power AC Drive with advanced cooling • Ratings through 1.5 MW • Modular Design • IP52 standard • IP54 and greater available (consult factory) The AC890PX Cool Drive is an extension of the popular AC890PX series. By using Parker’s Advanced Cooling technology, the Cool Drive offers the highest power density available, meaning less floor space per kilowatt.
What is “CoolDrive”Extension of AC890PX with Advanced Cooling• Increases power range• Industry leading power density• Increased reliability and lower risk• High environmental protection• Re‐uses majority of AC890PX electrical design• Patented: Patent on air cooled AC890PX Provisional patent on CoolDrive• Future compact 3 phase modules for mobile applications
400KW – 1.5MW Cool Drive Dimensions AC Fed Inverter 2500H x 2200W x 800D (mm) DC Fed Inverter 2500H x 1200W x 600D (mm) 4Q AFE/Regen 2500H x 2800W x 600D (mm) Note: Dimensions depend upon the IP rating selected and include a 100mm base and 400mm condenser.
Modular Design• Pluggable Power Modules • Sealed modules can be replaced in minutes • Inverter Modules weigh under 50 pounds • Replaceable by local service staff • Freight-friendly, easily shipped around the globe • Packaged and designed to clear customs quickly• Integrated bus system • Power wiring minimized • Keyed modules eliminate errors • No-leak dry break fittings eliminates coolant loss
