The model code decodes cleanly: '21' marks the single-phase 230V input, 'A' denotes the version/type, 'B' is the B-series platform, and '015' is the 1.5 kW frame. The unit falls inside Delta's 1–2 HP (0.75–1.5 kW) power band, which is the common slot for retrofitting fixed-speed single-phase motors onto a variable-speed bus. ## What the operational ratings drive Overload endurance is 150% of rated current for one minute, which sets the headroom for breakaway torque on conveyors or compressor start transients before the drive trips into current limit. Stall prevention is configurable from 20% to 250% of rated current — a wide enough window to clamp to the driven load rather than the drive's own ceiling. Frequency setpoint resolution is 0.01 Hz, and three skip-frequency zones are programmable across 0.1–400 Hz — useful for steering past mechanical resonances in fans, pumps, and belt-driven machinery. Ambient operating humidity is rated below 90% RH non-condensing; storage and transport temperature spans −20 °C to 60 °C, which is the handling envelope to respect when staging drives on a panel-build floor or shipping them to a remote site. Fan cooling is built in, so the enclosure layout needs to preserve the drive's airflow clearance. ## Procurement posture and project fit Ordering is handled through independent distribution against an RFQ — pricing, current availability, and the project-specific delivery slot are all confirmed at quote time.
