What VFD007E43T is doing in the panel
Delta VFD007E43T is a 1 HP / 2.5 A inverter drive in the 480 V 3-phase class, sized for fractional-HP induction motors on US 480 V plant buses where the input envelope of 380-480 V AC covers both European and North American supplies without a step-down transformer. The control scheme is open-loop / sensorless vector with no closed-loop encoder option on this variant — that is the right pick for standard pumps, fans and conveyors where encoder feedback is overkill, but not for the holding-torque or low-speed full-load cases that demand a closed-loop drive.
480 V input and braking on board
Nominal input is 480 V AC across a 380-480 V range, 3-phase — connect the /L2/L3 feed from a 480 V 3-phase feeder, never single-phase, and size the upstream breaker per the 2.5 A continuous figure rather than the 1 HP nameplate alone. Braking is handled by DC injection plus a built-in dynamic braking transistor, so a stopping resistor drops onto the DC bus with no extra chopper hardware; AC line regen is not built in — high-inertia decel profiles that regenerate heavily will still need an external braking resistor sized to the deceleration duty cycle. Maximum output frequency tops out at 600 Hz, well above any 50/60 Hz motor application, which leaves headroom for high-speed spindle duty without forcing a different drive family.
Panel fit and operator keypad
The operator keypad is sold separately — order the matching Delta display / parameter-copy unit if the application needs local start/stop and speed reference from the front of the cabinet, otherwise the drive is configured through the PC tool or remote I/O at commissioning.
Lifecycle and supply posture
Lifecycle stage on the official Delta record is current — no PCN or last-time-buy window on this code, so it slots into an active BOM without an immediate obsolescence hedge. Lead time is typically 1-10 working days; for a tail-spend buyer consolidating onto a preferred-supplier catalog, the unit is a punch-out candidate rather than a one-off requisition, with the BOM specifying the 480 V 3-phase input and the open-loop control scheme as the gating line-items.
