Product Description

The 07.F4.CRD-3420 frequency inverter is a compact and efficient solution designed for industrial motor control applications. It is ideal for environments requiring precise speed and torque management of three phase motors.

This F4 Combivert series frequency inverter provides a nominal output power range of 1.8 kVA. The inverter supports a maximum rated motor power of 0.8 kW and a nominal input current of 2.8. It operates with a three phase supply voltage range of 305 – 500 V. The inverter can deliver a maximum short time current of 4.6 A and withstands high braking currents up to 5 A. It includes overcurrent tripping protection set to 5.7 A providing enhanced safety during peak loads. The product supports both 4 kHz switching frequencies with stall currents at 4 kHz reaching up to 45 A. Its heat sink maintains a maximum temperature of 85 °C and it operates effectively in ambient temperatures from -10 °C to 45 °C. It operates within the climatic category 3K3 and is designed for indoor environments without excessive dust or condensation.

The 07.F4.CRD-3420 frequency inverter features a rated operating frequency of 4 kHz and a maximum frequency of 4 kHz with an efficient power loss at nominal operation rated between 45 W. The inverter operates on an IP20 protection level suitable for installations without condensation risks in industrial environments with up to 95 % relative humidity. It supports shielded motor line lengths up to 50 meters. The inverter’s braking resistor specifications are 160 Ω minimum and 390 Ω typical providing optimal energy dissipation during deceleration. The device’s line cross section is 1.5 mm² and it allows a maximum permissible fuse of 10 A for secure operation.
