ODE-2-24400-3K04N Variable Frequency Drive OPTIDRIVE E2 4.0kW 3-ф/380

ODE-2-24400-3K04N — Invertek Optidrive E2 rated 4.0 kW, three-phase 380 V input, three-phase 380 V output to the motor, 9.5 A rated current. A scalar (V/f) drive with no vector and no PLC, output frequency up to 500 Hz, IP55 enclosure.

Typical applications:

• Fans, blowers and extraction
• Mid- and higher-power pumps
• Conveyors, crushers and simple process machinery

Note: the …K04N variant includes a built-in braking circuit for an external resistor per the Invertek catalogue. For frequent reversals or high inertia the resistor is sized by calculation. Confirm the EMC filter and the build by part number. The series is discontinued — we can suggest a Veichi equivalent.

Invertek Optidrive E2 (ODE-2) — a simple V/f drive that just works, for pumps, fans and conveyors

The Optidrive E2 is the economy series from UK-based Invertek, built on the "Easy to Use Economy Drive" idea. The maker spells it out in the product line name — Volts-per-Hertz: this is a scalar (V/f) drive with no pretensions to complex motion control. In our range these are models from 0.7 to 7.5 kW in two input versions: single-phase 220 V with a three-phase 220 V output to the motor, and three-phase 380 V. The series is now discontinued (the successors are the Optidrive E3 and P2), so we supply it as a like-for-like replacement in existing panels and will honestly point you to a current equivalent.

What this drive is, and where it fits

• V/f (scalar) control: the Optidrive E2 is classic volts-per-hertz. There is no sensorless vector, no closed-loop encoder control and no built-in PLC. That is fine: a pump, a fan or a simple conveyor does not need vector control.
• Output frequency up to 500 Hz — enough for standard 50/60 Hz motors and for higher-speed spindles within the limits of scalar control.
• IP55 enclosure: a sealed housing you can mount next to the machine without a separate cabinet — handy on dirty or damp lines.
• Communication: the E2 series provides a built-in Modbus RTU over RS-485 for integration into basic automation.

Braking and EMC filter — check by part number

Braking on the E2 has a catch: the built-in braking transistor (a chopper for an external resistor) is not on every variant. The smaller single-phase and basic three-phase models often ship without a chopper, while the larger ones (frame size 2 and up, the …K04N part numbers) include the braking circuit. The same goes for the internal EMC filter: in the Invertek catalogue the three-phase 400 V EU variants usually carry an internal filter, but the exact build depends on the part number. So confirm the chopper, the EMC filter and the exact protection class by part number — we verify it against the datasheet before shipping, so you do not receive a "bare" unit where you actually need braking.

When Veichi is the more practical buy

If you are fitting a new drive rather than swapping an E2 like-for-like, it is worth comparing our Veichi range: AC10 — a compact V/f and vector drive for the same small jobs but with wider parts availability; AC310 — a universal industrial vector drive if you may later need low-speed torque; AC01 — specialised for single-phase pump applications. Unlike the discontinued E2, we keep these in stable supply and support them. Need help sizing one to a specific motor? Message us with the machine's nameplate.
