Product Description:
The 19.F5.CDH-YW0A is an axis inverter manufactured by KEB for the F5 Combivert Axis Drives series. It converts a three-phase mains supply into a variable-frequency output for controlling induction or synchronous motors in automated machinery. The integrated control and power sections support coordinated motion within the broader Combivert F5 platform. Manufacturer code 19 indicates the unit’s power class, while the H housing provides the corresponding physical form factor. The inverter is designed to deliver 40 horsepower of mechanical motor output when installed in a suitable control cabinet.
The power section has a nominal line voltage of 400 V AC and accepts an input range of 305 to 528 V AC without derating. This broad range allows the inverter to operate when the incoming mains voltage varies from its nominal level. The rectifier charges a DC bus with 2700 µF of capacitance, while a 31 A charging circuit limits inrush current as the capacitors energize. Excess regenerative energy can be dissipated through a 20 Ω load shunt. The apparent power capacity reaches 42 kVA, providing headroom for dynamic motor loads operating at a 0.9 power factor. The default switching frequency is 4 kHz, but it can be increased to 16 kHz when lower audible motor noise is preferred. Operation at the higher switching frequency increases thermal loading and may require additional attention to cabinet airflow.
The motor-side output can reach 108 A during short transient demands, supporting acceleration and other temporary peak-load conditions. Continuous output current is limited to 60 A to keep the power stage within its sustained thermal capacity. The maximum permitted ambient temperature is 45 °C, and standby power consumption is 62 W at that temperature. These values help determine the ventilation and heat-removal requirements for the surrounding enclosure. The open-frame housing has an IP20 ingress-protection rating, which protects against accidental contact with larger solid objects but does not provide water protection. The inverter weighs 14 kg, so the mounting surface must provide adequate support. Panel spacing should also leave sufficient room for natural convection around the heat sink and prevent nearby components from obstructing airflow.
