Product Description:

The 13.F4.S1E-5A10 is a frequency inverter produced by KEB within the F4 Combivert Frequency Inverters series. It converts fixed-frequency three-phase mains power into a variable frequency output that lets an automation controller regulate induction motor speed and torque. Used in conveyors, pumps, and general machinery, the drive forms the interface between a PLC and the motor, allowing acceleration, deceleration, and constant-speed operation to be programmed instead of relying on mechanical throttling or pole changing.

The inverter has an IP20 enclosure, so its terminals are finger-safe but the unit requires cabinet mounting. It draws a 13.2 A rated input current and can supply 12 A rated output current to the motor, while a 12 A standstill current maintains torque at zero speed. Carrier pulses switch at 16 kHz rated frequency, reducing motor noise and improving current control. Continuous delivery is 8.3 kVA output power, and the drive is sized for motors up to 5.5 kW maximum power. A 20 A maximum mains fuse must be fitted upstream to match the semiconductor limits.

A 73 °C maximum heatsink temperature defines the thermal ceiling; the control board initiates derating when this point is approached. Overall dissipation is 240 W power loss, so enclosure ventilation or a heat-spreader plate is required to maintain internal air below design limits. Regenerative braking is supported; during deceleration the drive can pass up to 15 A maximum brake current into an external resistor that must be at least 50 Ω, preventing over-voltage on the DC bus. Physical integration is aided by a 3.5 kg mass and a footprint of 130 mm width, 200 mm depth, and 290 mm height, allowing multiple inverters to be arrayed on a 35 mm DIN rail or back-panel without exceeding typical 300 mm cabinet depth.
