KEB 12F5C1B-350A F5 Compact Drive
Product Introduction
The KEB 12F5C1B-350A is a compact frequency inverter from the COMBIVERT F5 Series. This drive operates on 400 VAC three-phase power at 50/60 Hz. Its rated input current is 13.3 A, while the output current reaches 9.5 A. The output power is 4 kW (5 HP) with an apparent power of 6.6 kVA. You can use this drive for general purpose motor control in industrial environments.
Furthermore, the KEB 12F5C1B-350A delivers an output frequency range from 0 to 800 Hz. This wide range supports both standard pumps and high-speed spindles. The built-in sensorless vector control provides excellent torque performance even at low speeds.
Technical Specifications
The KEB 12F5C1B-350A includes 2 analog inputs and 8 digital inputs for flexible signal connection. For outputs, it offers 2 analog outputs and 2 relay outputs. Communication happens through RS485 (Modbus RTU) and RS232 interfaces.
Additionally, this drive has a built-in braking resistor for rapid deceleration. An EMC filter is available upon request to meet electromagnetic compatibility requirements. The enclosure rating is IP20, which protects against solid objects larger than 12 mm.
The operating temperature ranges from -10°C to +45°C. Storage temperature extends from -25°C to +70°C, making this unit suitable for various warehouse conditions.
Mechanical Dimensions and Mounting
The KEB 12F5C1B-350A has a compact footprint. Its height measures 22 cm (8.6 in) , width is 9 cm (3.5 in) , and depth is 16 cm (6.2 in) . The total weight is only 2 kg (4.4 lbs) .
Therefore, this drive fits easily into tight control cabinets. The IP20 protection allows installation inside clean, dry indoor environments. Always maintain proper clearance around the unit for adequate airflow.
Installation Guidelines
First, mount the KEB 12F5C1B-350A vertically on a flat, non-flammable surface. Next, connect the 400 VAC three-phase input to terminals L1, L2, and L3. Then, wire the motor to output terminals U, V, and W using shielded cables.
Meanwhile, connect your control signals to the analog and digital input terminals. Use twisted-pair cables for the RS485 Modbus RTU network to reduce noise. Finally, configure parameters using the keypad or software before starting the motor. Always follow local electrical safety codes.
Packaging List
Note: No communication cables, EMC filter (available upon request), or warranty documents are included.
