Lenze

Lenze’s E84AVSCE1524SX0 inverter, part of the Series 8400, is engineered to effectively manage 4-pole asynchronous motors, delivering a typical motor power output of 1.5 kW. This unit operates with a mains voltage range of 180 to 550 VAC, supporting frequencies between 45 Hz and 65 Hz. The rated mains current is 3.6 A when connected with a mains choke and can increase to 4.7 A without the choke.

Its rated output current is maintained at 3.9 A, which matches the output current level at an 8 kHz frequency. For short-term demands, the inverter can achieve a maximum output current of 5.9 A for 60 seconds or 6.8 A for 3 seconds.

The brake chopper integrated within this device can provide a rated power output of 2.9 kW, with a corresponding maximum power also set at 2.9 kW. For optimal operation, a minimum brake resistance of 180 ohms is specified. The DC supply voltage can range from 455 V to 775 V, ensuring compatibility with various input power configurations.

Regarding efficiency, power loss during operation is calculated at 48 W. For installation convenience, the inverter supports a maximum cable length of 50 m for shielded wires. Physical dimensions measure 165 mm in height, 70 mm in width, and 162 mm in depth, making it compact enough for various mounting settings.

The Lenze frequency drive model E84AVSCE1122SX0, from the Series 8400, is a reliable solution for efficient motor control. This device operates at a nominal voltage of 230 V AC and can function within an input voltage range of 180 to 264 V. For enhanced functionality, it is rated for power dissipation at 95 W under standard load conditions.

Temperature impacts the input current ratings, with a specification of 12.0 A at 45 °C and 9.0 A when the environment reaches 55 °C. The drive can output voltages from 0 to 230 V and function at frequency outputs of up to 1000 Hz. At 45 °C, the output current of this model is 5.5 A, and it reduces to 4.1 A at 55 °C.

Lenze's frequency drive provides flexibility in operation with selectable switching frequencies of 2 kHz, 4 kHz, 8 kHz, or 16 kHz, accommodating different application requirements. Additionally, it features an enclosure with an IP20 protection rating, allowing it to be used in various non-hazardous environments. Its design can tolerate operating temperatures up to 55 °C and provides an overload capacity of 150% of output current for a maximum of 60 seconds.

For control methods, it incorporates V/f mode and vector control capabilities without the need for an encoder, making it efficient for various motor control applications.
