Delta ME300 VFD0A8ME21ANNAA 0.1 kW 0.125 HP 230 V Single-phase VFD

Delta ME300 VFD0A8ME21ANNAA 0.1 kW 0.125 HP 230 V Single-phase VFD

The Delta VFD0A8ME21ANNAA is a ME300 variable frequency drive with a manufacturer-listed motor capacity of 0.1 kW / 0.125 HP on the HD rating basis. This complete ordering code identifies single-phase 200–240 V AC input and three-phase motor output. It has no built-in EMC filter. The specification table below uses the exact model code and the documented duty ratings. A separately ordered motor, braking resistor, reactor, mounting adapter or communication accessory is not included by these specifications.

Electrical Ratings

Nominal input is 200–240 V AC, with −15% / +10% tolerance. Input frequency is 50 / 60 Hz; range: 47–63 Hz. Rated input current is HD: 2.2 A; ND: 2.8 A. Continuous output current is HD: 0.8 A; ND: 1 A. These input and output currents are different quantities and must not be interchanged when selecting wiring or protection. The motor capacity is the manufacturer-listed pairing rather than a calculated HP conversion. Output frequency is 0–599 Hz. The numerical output-voltage rating remains unverified in the reviewed documents. Motor speed, insulation and machine limitations still govern the usable operating range.

Control Modes and Performance

Supported motor categories are IM, IPM, SPM. The documented control modes are V/F, SVC. V/F provides adjustable voltage/frequency control, while SVC supports sensorless operation within the documented motor-type limits. The series supports two independent motor parameter sets. Its PID, pump and simple positioning functions require appropriate application settings. Duty selection is Heavy Duty / Normal Duty. Temporary overload capability is HD: 150% / 60 s, 200% / 3 s; ND: 120% / 60 s, 150% / 3 s. Each overload percentage refers to its corresponding continuous duty current, rather than the electrical input current. Temporary overload capability does not increase the continuous motor-current rating. The catalogue states the overload percentages and durations. A repetitive overload cycle must follow the applicable manual and the actual thermal loading.

Communication and Configuration

Built-in communication is Modbus (RS-485). Optional communication is Not specified. The standard serial connection uses RS-485 with Modbus. No unverified Ethernet or fieldbus expansion is included in the product claims. The operator panel is Built-in digital keypad. Built-in PLC: No. Programming capacity: N/A. The manual explicitly excludes the PLC Function and Copy PLC menu functions for ME300. Multi-step speed, PID and positioning features do not establish a built-in ladder-programmable PLC. Digital input: 5 × 24 V DC, sink/source. Digital output: 1 transistor + 1 changeover relay. Analog input: 1: 0–10 V or 0/4–20 mA. Analog output: 1: 0–10 V.

Braking, EMC and Integrated Functions

This exact variant has no built-in EMC filter and no integrated STO. Built-in braking chopper: Yes. Braking resistor: External. DC reactor / choke: Optional. The catalogue lists a built-in braking chopper throughout the series. The wiring diagram shows separately selected external braking-resistor and DC-choke connections. The resistor and braking chopper are separate components. A built-in chopper does not establish that a braking resistor is installed inside the drive. Accessory selection must follow the relevant model table and the actual acceleration, stopping and load cycle. Filter configuration follows the supplied ordering code, so a filtered variant must not be substituted for an unfiltered product or the reverse.

Installation and Typical Applications

The documented protection configuration is IP20 / UL Open Type. Frame size is A1. Overall dimensions are 68 × 128 × 78 mm (W × H × D). Mounting type is Panel / screw; optional DIN rail (MKM-DRB). Install the drive inside a suitable control cabinet, observing its grounding and airflow-clearance requirements. The catalogue lists IP20 / UL open-type operation from −20 to +50 °C, with derating above +50 °C within the specified limit. Higher altitude and side-by-side mounting have separate derating conditions. Dimensions exclude optional mounting accessories. Delta presents fans, pumps, conveyors, blowing machines, packing machines and woodworking equipment as ME300 family applications. The selected motor current, duty rating, control mode, enclosure and braking arrangement must meet the actual application. Family application examples do not establish unconditional compatibility for every machine or motor size.

Exact Variant Verification

Use the complete part number VFD0A8ME21ANNAA when comparing quotations, replacement equipment and the supplied nameplate. Power, supply phase, voltage class, filter, safety and enclosure options can change between nearby ordering codes. The source ordering information and model rating tables were checked for this catalogue entry. Remaining evidence gaps are recorded in the source area. Warranty is 12 Months under PLC Store BD’s store policy.
