I found the ATV312HU22N4 datasheet information for you! This is a Schneider Electric Altivar 312 variable speed drive with the following key specifications:
• Power rating: 2.2 kW (3 HP)
• Supply voltage: 380-500V, 3-phase
• Apparent power: 5.9 kVA
• Line current: 8.9A at 380V, 6.7A at 500V
• Output frequency range: 0-500 Hz
• Carrier frequency: 2-16 kHz adjustable
It's worth noting that this model appears to be discontinued and is now only available for service purposes. The drive comes with a heat sink and is designed for industrial motor control applications.
