E82EV371K2C Lenze 8200 Vector Frequency Inverter – Compact 0.37 kW Drive
The E82EV371K2C is a built-in vector-controlled inverter from the Lenze 8200 vector series. It drives a 0.37 kW four-pole asynchronous motor on a 230 V single-phase supply. The unit combines a vector control core, an integrated EMC filter and a built-in brake chopper in one compact housing. It suits machine builders who need reliable speed control in a small panel space.
This drive is a legacy model. Lenze lists it on the official previous products page. The i950 generation replaces it, and Lenze confirms that i950 emulates 8200 vector behaviour through the i950 PROFIBUS module and the L_ICIP library. There is no drop-in replacement with the same order code, so plan a migration path for new designs.
Why This Drive Stands Out
- Integrated EMC filter cuts external filter cost and wiring time.
- Built-in brake transistor supports fast stops without extra hardware.
- 1.8 x rated torque for 60 s handles short load peaks with margin.
- 2/4/8/16 kHz switching frequency lets you trade noise against losses.
- Output up to 650 Hz covers high-speed spindle and tooling duties.
- Plug-in communication slots open PROFIBUS DP, CANopen, DeviceNet, INTERBUS and AS-Interface.

Installation Guide
- Mount the unit vertically on a flat panel. Keep the IP20 housing inside a protective enclosure.
- Respect the 120 x 60 x 140 mm footprint and leave free space above and below for airflow.
- Wire the single-phase 180 to 264 V AC supply to the mains terminals. Check polarity and grounding first.
- Connect the motor to the output terminals. Match the 2.4 A rated current to the motor nameplate.
- Derate output by 2.5 percent per °C when the ambient rises above +40 °C.
- Use the integrated EMC filter to meet emission limits. Keep motor cables short and shielded.
- Fit an external braking resistor when the built-in chopper handles stop energy.
- Set the switching frequency to 8 kHz for standard duty. Raise it only when motor noise matters.
Commissioning and Maintenance
- Enter motor data through the keypad or the RS232/RS485 system bus.
- Run the auto-tune routine so vector control matches the connected motor.
- Set 1.8 x torque overload limits to protect the 0.37 kW motor.
- Check fan airflow and terminal torque at each service interval.
- Clean the heatsink when dust builds up in the enclosure.
- Review fault logs through the serial bus to spot repeat trips early.

Expert Review
This unit earns its place in small machines where panel space is tight. The integrated filter and brake chopper remove two external parts from the bill of materials. Vector control keeps torque steady at low speed. The 1.8 x overload window covers most start-up peaks on a 0.37 kW motor. The main limit is lifecycle. Buyers starting a new platform should budget for the i950 migration, because Lenze offers no same-code swap. For spare parts and existing machines, the E82EV371K2C remains a sound choice.
Manager’s Insight
We keep this model for maintenance and retrofit demand, not for new series production. The 8200 vector family is proven in the field, and the migration path to i950 is documented. Customers who order this drive usually need an exact fit for an existing panel. That is why we hold stock and ship fast. Ask us for the i950 cross-reference if you plan a new design.
Best Fit Devices and Applications
- Small conveyors and indexing belts.
- Pumps and fans with variable flow demand.
- Packaging and labelling stations.
- Textile and wire winding machines.
- Door and gate drives with braking duty.
- Retrofit projects replacing an old 8200 vector unit.
FAQ
Q: Can this drive run a 0.37 kW motor on single-phase 230 V?
A: Yes. The E82EV371K2C is built for a 0.37 kW four-pole motor on a 180 to 264 V AC single-phase supply.
Q: Is a braking resistor included?
A: No. The brake transistor is built in, but you must add an external resistor for stop energy.
Q: Does it support PROFIBUS?
A: Yes, through a plug-in communication module. The base unit ships with RS232 and RS485 only.
Q: What replaces this model in new designs?
A: Lenze points to the i950 series with the i950 PROFIBUS module and the L_ICIP library. There is no same-code drop-in unit.
Q: How much overload can it take?
A: It delivers 1.8 times rated torque for 60 seconds, which covers most start peaks on small motors.
Q: Can I supply it from a DC bus?
A: Not on this model. The DC 260 to 370 V option excludes the E82EV251 and E82EV371 units.
Q: How fast do you ship?
A: We dispatch in 12 to 24 hours by FedEx, UPS or DHL.
Q: What is the warranty?
A: 12 months from the ship date.
Q: How do I choose between this unit and a newer drive?
A: Pick the E82EV371K2C when you need an exact replacement for an existing 8200 vector panel. Pick the i950 when you are building a new machine and want current lifecycle support. Check motor current, supply type and fieldbus needs before you order.
Q: My old drive trips on overcurrent. What should I check first?
A: Check motor cable shielding and length first. Then verify the motor data entered in the drive. A worn motor bearing can also raise current, so inspect the load side.
