Product Description:

The Danfoss 134F4969 Frequency Converter supports a wide voltage range and precise frequency adjustment. Its design ensures consistent current handling, overload protection and safe operation under varying environmental and load conditions.

The 134F4969 frequency converter is a three phase unit designed for dependable motor control across a voltage range of 380 – 500 VAC. The converter is designed for applications requiring continuous current control and efficient handling of load variations while maintaining reliable operation in industrial environments. The unit has a continuous output current rating of 7.2 A under high overload conditions with an intermittent current capacity of 11.5 A. The converter records a power loss of 116 W under standard operation. The motor output voltage ranges from 0 to 100 % of the supply while the output frequency spans from 0 – 590 Hz with flux mode allowing up to 300 Hz. The ramp times are adjustable between 0.01 and 3600 seconds that offers precise speed and torque control. The torque characteristics include a starting torque capacity of up to 150 % of the nominal drive current for 60 seconds and overload torque at the same percentage for 60 seconds that allows robust performance during demanding start up and load fluctuation scenarios. These values can be sustained once every ten minutes.

The 134F4969 frequency converter is engineered to maintain performance across different application requirements. It is built with an IP20 chassis enclosure for protection and compact installation. The unit operates at full scale from a minimum ambient temperature of 0 °C with reduced performance available down to -10 °C. The converter can function without derating up to 1000 meters above sea level and allows operation with derating up to 3000 meters.

Frequently Asked Questions about 134F4969:

Q: What protective features help the 134F4969 frequency converter maintain reliable operation in compact enclosures?

A: It features an IP20 chassis that protects internal components during standard panel installations. This compact form factor supports industrial setups with limited space and moderate environmental exposure.

Q: How does the 134F4969 converter handle start-up torque in heavy-load environments?

A: It delivers up to 150% of nominal current for 60 seconds to support demanding startups. This torque reserve ensures stable performance during sudden load application or motor acceleration.

Q: What output frequency flexibility does the Danfoss 134F4969 offer for precision-driven tasks?

A: It allows output frequency control up to 590 Hz, with flux mode extending operation to 300 Hz. This supports fine-tuned motor response in variable speed or high-frequency applications.

Q: How does the 134F4969 frequency converter maintain current stability during thermal or altitude shifts?

A: It operates without derating up to 1000 meters and maintains limited functionality up to 3000 meters. Performance remains consistent even under reduced temperature or elevated location setups.

Q: In what way does the ramp time configuration support dynamic load applications in the 134F4969 model?

A: Ramp time adjustability from 0.01 to 3600 seconds allows precise control over acceleration and deceleration. This reduces mechanical stress and enhances motor response across shifting load demands.
