Difference between ATV61KD18N4 and ATV61HD15N4
ATV61HD or ATV61KD drives
All ATV61 drives to 100 hp
PN+1, Power Identification change for enclosed drive products.
All E-Flex, M-Flex and PowerGard enclosed adjustable speed drive controllers utilize the ATV61 power converter in a customized hardware and software configuration where the product gains a horsepower rating for devices configured in IP00 with a 3% line reactor (or DC Choke). The power converter is programmed by Quality Assurance personnel for these settings to match NEC2005 Table 430.250 for 460V and 230V configurations only.
The drive HP/kW sticker (or imprint) on the cover of the power converter component used within the E-Flex or M-Flex enclosure may not necessarily reflect the correct markings for the enclosed package. However, the graphic terminal display will reflect the correct rating from the factory and should match the enclosed drive controller nameplate and should be observed for the application.
