Product Description:

The 134F2972 Frequency Converter is an efficient electronic motor controller designed to convert AC mains input into variable AC waveform output. It regulates motor speed and torque with precision for stable operation.

The Danfoss 134F2972 frequency converter provides a shaft output power of 0.75 kW and is designed with an IP20 enclosure protection rating. It ensures reliable operation across industrial environments. The continuous current rating of the model is 2.2 A at 380 – 440 V AC and 2.1 A at 441 – 480 V AC that is suitable for a wide input voltage range. The unit supports intermittent current overload of 3.5 A for 60 seconds for safe short term high demand operation. At continuous operation, the converter delivers 1.53 kVA at 400 V AC and 1.7 kVA at 480 V AC. The maximum input current is specified as 2.1 A at 380 – 440 V AC and 1.8 A at 441 – 480 V AC. The unit tolerates up to 3.4 A during intermittent overload conditions. The converter supports a maximum cable cross section connection of 4 mm2 including mains, motor, brake and load sharing terminals. The converter includes provisions for system integration with external networks via status indications or communication signals.

The 134F2972 frequency converter has an estimated power loss of 30.01 W at rated load. The unit maintains a compact design without compromising output by weighing only 2.3 kg. The efficiency of the model is measured at 97.2 % which significantly reduces energy losses. In addition to current and voltage regulation, the device actively monitors motor conditions, responds to system commands and issues alarms for faults. The converter also provides start and stop control, energy optimization functions and effective motor protection.
