That 150% overload endurance for 1 minute means it can handle short-duration torque peaks—like starting a loaded conveyor or crusher—without tripping. The 0.01 Hz frequency-setting resolution gives fine speed control for applications where tight regulation matters, like a pump or fan following a pressure setpoint. ## Sizing and overload headroom The 150% overload for 1 minute is the figure that decides whether this drive holds a motor through a hard start. For a 25 HP motor driving a high-inertia load—say a centrifuge or a large fan—that minute of headroom buys you time to ramp up without nuisance tripping. The stall prevention level is adjustable from 20 to 250% of rated current, so you can dial it in to match the motor's thermal curve. ## Environmental limits and mounting This drive is fan-cooled, so panel placement needs clearance for airflow. Ambient humidity below 90% RH (non-condensing) keeps the electronics dry. Storage temperature from -20°C to 60°C covers most warehouse conditions, but the operating range is narrower—plan for a ventilated enclosure if the panel sees summer heat.","metaTitle":"Delta VFD0185B43A AC Drive, 25 HP, 460V Three-Phase, B Serie","metaDescription":"Delta VFD0185B43A AC drive rated 25 HP (18.5 kW) at 460V three-phase input, B series. 150% overload for 1 minute.
