Overview
The Delta VFD007EL43A is a compact, multi-function micro AC drive from the VFD-EL series. The inverter VFD-EL series is a multiple function new generation micro type AC drive. Rated at 0.75 kW (1 HP), this three-phase drive operates on 380–480V nominal input and delivers precise motor speed control via V/Hz scalar control. Designed for space-constrained industrial environments, the VFD007EL43A combines robust protection, simple operator controls, and communication flexibility in a micro enclosure.
Key Features
- Built-in EMI filter and RFI-switch for IT mains
- Three phase input with 6-key 7-segment LED with 4-digit display
- Output frequency 0.1 to 600 Hz with 3 points adjustable V/f curve
- Built-in PID feedback control and RS-485 communication interface (RJ-45) with Modbus protocol
- High precision current detection, overload protection, and easy DC bus sharing for side-by-side installation
- Compact micro design with IP20 rating for industrial floor mounting
