Product Description:
The FC-202PK55T2134X8141 is an AC variable frequency drive manufactured by Danfoss for the VLT FC 202 AQUA Drives series. In pump, blower, and filtration systems, the unit adjusts motor speed to maintain constant pressure or flow, reducing energy consumption in industrial and municipal water applications. Its control functions allow motor output to follow changing process demand instead of requiring continuous operation at full speed. This operating approach is suitable for small pumping systems that need stable pressure, controlled flow, or level regulation.
The rated motor output is 0.55 kW, which is equivalent to 0.75 HP, making the drive suitable for small centrifugal pumps or compact compressors. A continuous output current of 3.5 A supports this power level, while an efficiency of 0.95 limits conversion losses to 42 W at full load. On the supply side, the maximum input current is 3.2 A, allowing the unit to operate on standard branch circuits with suitable protection. The drive accepts three-phase mains power and supports a 10 A pre-fuse. Its programmable analog output provides 8-bit process feedback and can operate with a load of up to 500 Ω. These electrical characteristics help determine branch-circuit protection, conductor selection, and enclosure ventilation requirements.
The pulse-width modulated inverter can switch at frequencies up to 32 kHz, allowing acoustic noise to be balanced against motor heating. The control interface provides four standard digital inputs, expandable to six, for start commands, pressure switches, float sensors, and similar field devices. A single analog output with 8-bit resolution can provide a speed reference or positioning signal for compatible equipment. The acceptable mains voltage range is 200–240 VAC, matching common low-voltage pump installations. The drive connects to the motor through power leads that accept conductors up to 4 mm². Braking energy can be dissipated through an external resistor with a minimum resistance of 275 Ω and a nominal resistance of 313.7 Ω. Observing the minimum brake resistance prevents excessive transistor current during motor deceleration.
