Expert Review

The EVF8245-E is a robust choice for standard pump, fan, and conveyor applications. Its 150% overload capacity handles peak loads well. The selectable FTC mode improves torque stability at low speeds. As a legacy model, it is ideal for maintenance and spare-part replacement. New designs should consider newer Lenze series. For urgent needs, Powergear X offers fast dispatch.

Manager’s Insight

This inverter balances proven reliability with flexible communication options. The pluggable module slot lets you adapt to different fieldbuses without replacing the drive. The wide voltage range (320–528 V AC) supports global installations. For legacy systems, the EVF8245-E reduces downtime because it matches existing wiring and parameters.

Best Suited Devices and Applications

• Pumps and fans – variable torque loads benefit from V/f control
• Conveyors and material handling – stable torque with FTC mode
• Legacy machine retrofits – drop-in replacement in 8200 series cabinets
• Standard industrial drives – 5.5 kW motors at 400 V

FAQ

Q: What is the overload capacity?

A: 150% of rated output current for 60 seconds. This handles short-term peak loads.

Q: Can I use fieldbus communication?

A: Yes. The built-in slot accepts Lenze communication modules (LECOM or bus modules). No fieldbus is integrated as standard.

Q: How do I mount the inverter?

A: Install vertically in a control cabinet. Ensure clearance for airflow. IP20 rating requires a protected environment.

Q: Does it work with 50 Hz and 60 Hz supplies?

A: Yes. The supply frequency range is 45 to 65 Hz.

Q: What is the recommended ambient temperature?

A: 0 to +40 °C without derating. Above 40 °C up to 50 °C, derate 2.5% per K.

Q: Is this a current production model?

A: It is a legacy model, superseded by newer Lenze series. Stock may be limited. Contact us for availability.

Q: How fast is shipping?

A: We dispatch within 12–24 hours via FedEx, UPS, or DHL.
