The Lenze EMB9343-E is a specialist within the Series 9300, functioning as a regenerative power supply that both conserves and manages electric energy. It offers continuous power output of 27.0 kW on the DC bus, which can peak at 40.5 kW when energy demands are high. On the mains side, its apparent power is rated at 31.2 kVA, ensuring stable performance across applications.

When utilized in motor mode, it generates shaft power of 24.0 kW, while switching to generator mode allows for an output of 30.0 kW. This versatility is beneficial for systems requiring both energy capture and distribution. The input voltage range spans from 320 V to 528 V, compatible across various setups.

The EMB9343-E manages an input frequency between 48 Hz and 62 Hz, enabling flexibility in deployment. With a weight of only 12.5 kg, it remains relatively lightweight compared to its capabilities. The nominal AC current drawn is 45 A, but it can tolerate a maximum AC current of 67.5 A when necessary.

For the DC bus, continuous operation is sustained at 48 A, and it can peak at 72 A, indicating robust performance under variable conditions. The unit accounts for power loss, which is documented at 400 W, ensuring efficient operation. It's crucial to note the ambient temperature derating of 2% per K above 40°C, which should be considered during installation and use to maintain optimal performance.
