The 41.5 A rated output current is the continuous figure the drive can deliver to the motor; the heavy-duty rating of 41.8 A and normal-duty rating of 45.7 A tell you the overload headroom — heavy duty for constant-torque loads like conveyors or extruders, normal duty for variable-torque fans and pumps. Natural cooling means no fan to fail or clog, but it also means the drive sheds heat through the heatsink alone, so panel airflow matters — don't box it in tight with heat-sensitive kit. ## Frame size and panel fit Frame F is the physical footprint — it tells you the mounting hole pattern, gland-plate space, and bus-bar layout without pulling the manual. If you're swapping an older drive into an existing panel, check that the Frame F cutout and fixing centres match the legacy footprint — Delta's Frame F is a known size across this series, so a retrofit often lands without re-drilling the backplate. ## Carrier frequency and cooling Carrier frequency is adjustable from 2 to 15 kHz, factory-set at 4 kHz. A higher carrier quiets the motor but increases switching losses in the IGBTs — with natural cooling, pushing above 8 kHz may require derating the output current. The 47–63 Hz frequency tolerance means it handles genset or weak-grid supply without tripping.","metaTitle":"Delta VFD38AMH43ANSAA Frame F Drive, 18.5 kW, 41.5 A","metaDescription":"Delta VFD38AMH43ANSAA Frame F AC drive, 18.5 kW / 25 HP, 41.5 A rated output.
