Product Description:

The FC-202N160T7134G8765 is a variable frequency drive produced by Danfoss within the VLT FC 202 AQUA Drives series. Designed for pump, blower, and fan duties in water and wastewater facilities, the unit converts a fixed mains supply into a modulated output that allows precise control of motor speed and torque. By integrating brake chopper components and dedicated pump algorithms, the drive supports energy-efficient regulation of centrifugal equipment while maintaining the protection levels required in industrial automation.

The drive is rated for 160 kW, which equals 225 hp of continuous mechanical output at the motor shaft. It operates from three-phase power, and its efficiency meets the IE2 class, so input power is converted to torque with limited loss. A control platform operating at switching frequencies up to 32 kHz produces precise voltage pulses that reduce motor noise. The onboard braking hardware dissipates surplus energy during deceleration. Horizontal duty can absorb 13.0 kW, whereas vertical duty can handle 60.0 kW. The chopper has a nominal resistor value of 6.1 Ω and a recommended value of 7.2 Ω to keep component temperatures within acceptable limits. The drive sends logic, relay, and frequency signals over digital outputs without derating.

The converter maintains full current up to 1000 m above sea level; beyond this height, power derates linearly until operation ceases at 3000 m. Ambient air may reach 50 °C or fall to 0 °C without forcing a shutdown, and the circuit boards tolerate a noncondensing relative humidity of 95%. For rapid stopping, the integrated chopper may be paired with a resistor no smaller than 4.2 Ω to keep transistor junction temperatures within safe limits. Motor terminals can be connected with shielded conductors as long as 150 m, allowing pumps to be installed far from the electrical room while still meeting electromagnetic compatibility requirements.
