12.F4.S1D-4003

Product Description

12.F4.S1D-4003 is a 6.6. kVA rated frequency inverter. It is designed by KEB Automation for motor control applications. The peak power rating for the motor that can be connected to the inverter is 4 kilowatts. Weight of the unit is approximately 2 kilograms. Its dimensions are 240 x 90 x 160 millimeters. Installed accessories include a filter, a brake transistor and a brake resistor. Weight of the filter is 0.9 kilograms and weight of the braking resistor is 0.9 kilograms. The compact frequency inverter has an IP20 rated enclosure which is suited to indoor use. The IP rating specifies the degree of protection provided by enclosures for electrical equipment against solid objects and liquids. The IP code consists of two digits: the first digit indicates the level of protection against solid objects and the second digit indicates the level of protection against liquids.

IP20 means the inverter is protected from accidental contact with objects that can cause harm and there is no protection against water ingress. As the inverter is not dust-tight nor protected from water ingress, and it should not be exposed to moisture or wet conditions. Input voltage rating for the 12.F4.S1D-4003 inverter is 400 Volts AC (three-phase, 50/60 Hertz). Nominal values for input and output current are 10.5 Amps and 9.5 Amps respectively. The peak short-time current rating is 17.1 Amps and the OC-tripping current value is 20.9 Amps. The 12.F4.S1D-4003 inverter is designed for 4 kilohertz switching frequency. Its nominal power loss during operation is 115 Watts. The inverter has a heat sink with internal cooling fan. During operation, the heat sink temperature should be less than or equal to 85 degrees Celsius.
