22F-B025N104 — V-mini Micro Drive, 240V Three-Phase Input, 2.5A, 0.55 kW

The 22F-B025N104 is a V-mini series variable frequency drive rated at 0.55 kW / 0.75 HP, accepting 200–240V AC three-phase input and delivering 2.5A output. It shares the 55 mm mounting width of the entire V-mini range, V/Hz control mode, and the same four-digital-input / one-analog-input I/O complement. Where it differs from the smaller V-mini drives is the output current — 2.5A covers more substantial 240V three-phase motor loads that the lower-current variants can't drive.

At 0.55 kW / 240V, this drive targets small industrial motors in the ¾ HP class: compact conveyor drives, small centrifugal pump drives, agitator motors on mixing tanks, and cooling fan drives on industrial equipment. The V-mini's compact footprint means six drives of this rating take under 330 mm of DIN rail — a meaningful space advantage in a dense panel with multiple independent motor drives at similar power levels.

Running at 2.5A — What Changes Relative to Smaller V-minis

The V-mini range extends from fractional-amp units up through this 2.5A model. At 2.5A output on 240V, the motor load is at the point where motor current becomes a meaningful number in terms of panel current budgeting. Six drives at 2.5A output simultaneously draw up to 15A from the panel's 24V DC supply rail — that's before accounting for the additional supply current each drive draws from its own AC input branch circuit.

The AC input current per drive also deserves attention. On a 240V three-phase supply, 0.55 kW at typical efficiency draws approximately 2–2.5A AC per drive. With multiple V-mini drives on the same feeder circuit, the cumulative current adds up. Each drive should have its own dedicated input circuit breaker or fuse, and the panel's feeder must be sized for the total load including the inrush current that occurs when multiple drives start simultaneously — DC bus capacitor charging on startup can briefly draw 3–5× the steady-state input current per drive.

FAQ

Q: Can this drive connect to a 208V three-phase supply?

Yes. The input voltage range is 200–240V three-phase, which includes 208V. The drive operates normally across this range; output voltage will track the input voltage, so verify the motor is rated for operation at 208V.

Q: Is there a way to add a fieldbus communication port to this drive?

No. The V-mini series has no option port and cannot accept communication expansion cards. For EtherNet/IP, DeviceNet, or other fieldbus connectivity, a 22A or 22B series drive with an option port is required.

Q: Can the drive run a motor at very low speeds — below 5 Hz?

V/Hz control produces reduced torque at low frequencies. For standard TEFC motors, running continuously below 10 Hz at significant load can cause overheating because the motor's shaft-driven cooling fan doesn't move enough air. For applications requiring substantial torque at near-zero speed, a drive with sensorless vector mode or an externally ventilated motor is the appropriate solution.

Q: What is the typical startup current surge from the DC bus charging?

On initial power application, the DC bus capacitors draw a brief inrush current as they charge. For the V-mini at this power level, this pulse lasts a few milliseconds and can be 3–5× the steady-state input current. This is why input protection should be sized for the inrush rating in the drive's installation data, not just the running current, to avoid nuisance breaker trips on startup.
