Product Description:

The FC-202P75KT6134N2134 is an AC variable-frequency drive built by Danfoss for the VLT FC 202 AQUA Drives series. Designed for three-phase power systems, the device modulates motor speed to match changing process requirements. This control allows fluid-handling equipment to respond to demand without mechanical throttling, which is often required in industrial automation and water-processing installations.

The drive operates with an efficiency of 0.98, meaning only 2% of the input energy is lost as heat during nominal operation. The input section accepts 525–600 V AC and draws a continuous line current of 91 A, while delivering a steady motor current of 100 A. At this operating point, the apparent power reaches 99.6 kVA. The output transistors can switch at frequencies up to 32 kHz, allowing fine torque control at low motor speeds. Two programmable analog outputs supply 0 or 4–20 mA signals and can drive loads with resistance as low as 500 Ω. A digital transistor output supplies 40 mA for status indication. The controller samples internal parameters every 5 ms, keeping feedback channels and protective routines synchronized with rapid process changes.

During short overloads, the input current may rise to 100 A, and the inverter can provide an intermittent shaft current of 110 A to clear pump blockages or accelerate large impellers. Upstream protection requires fuses rated at 225 A, and the internal bus can withstand a short-circuit current of 100,000 A rms. During heavy loading, the power section dissipates 1,500 W. Cabinet ventilation or heat sinks must remove this thermal output to keep semiconductor temperatures within acceptable limits. The overload capacity supports brief increases in motor demand without requiring the drive to operate continuously above its normal current rating. Appropriate protective devices and adequate airflow are necessary when the drive is installed in motor control centers, switchgear, or process skids.
