ATV312HU40N4 | Schneider Altivar 312 VFD | 4kW 500V 3-Phase

ATV312HU40N4: Schneider Electric Altivar 312 VFD – 4kW, 500V

Designed for three-phase asynchronous motors, the Schneider Electric ATV312HU40N4 is a strong variable speed drive (VFD). This 4kW (5.5 HP) drive is a must-have for advanced automation schemes because it has the optimal blend of small size and advanced motor control.

The Altivar 312 series is well-known for its plug-and-drive feature, which includes built-in communication protocols and an easy-to-use interface that cuts down on commissioning time. This is very important when you have to do maintenance during a short port stay or a busy factory shift.

Documentations

Where to Use?

• Pumping & Ventilation: Ideal for centrifugal pumps and HVAC fans where energy savings through speed modulation are paramount.
• Conveyor Systems: Smooth acceleration and deceleration ramps prevent mechanical wear and tear on belt systems.
• Material Handling: Reliable torque control for small hoists and packaging machinery.
• Maritime Auxiliaries: Frequently used for engine room ventilation fans and fuel transfer pumps.
• Specialized Machinery: Woodworking, textile machines, and mixers requiring precise speed regulation.

Our Engineer’s Tips:

-> It’s important to manage heat: The ATV312 can handle temperatures up to 50°C, but make sure there is always clear vertical ventilation. You might want to utilize an IP54 enclosure with a heat exchanger to keep the PCB from sweating if you work in an area with a lot of humidity, like the engine room of a ship.

-> Cable Shielding: Always use shielded motor cables, and make sure that the shield is grounded at both ends of the drive and the motor with high-quality EMC clamps. This will assist the wires in passing tests that check for a lot of interference.

-> Firmware and Settings: Before you start the motor, always check the nameplate. Putting the correct I_n (nominal current) and Cos \phi (power factor) into the drive is what makes the difference between a protected motor and a burnt-out winding.
