Product Description:

The 134F2975 Frequency Converter delivers 2.2 kW shaft output and 3.0 HP power rating. The unit operates with three phase input voltage between 380 and 480 VAC.

This 134F2975 frequency converter provides consistent performance with high efficiency and stable output. The unit achieves efficiency of 97.6 percent at maximum shaft output of 2.2 kW. It supports continuous load operation with a rated apparent power of 3.68 kVA on 400 VAC input. The estimated power loss of the model at rated load is 73.97 W that ensures reduced thermal stress and extended lifetime. The frequency converter has a continuous apparent power rating of 3.68 kVA. This rating ensures reliable power delivery under steady state operation. The safety and reliability are emphasized in its installation requirements. The motor output cables from multiple converters must be routed separately to prevent induced voltage and capacitor charging hazards. The grounding clamps are included for motor wiring to ensure safe installation and operation. The manufacturer (Danfoss) advises against installing power factor correction capacitors between the converter and the motor. The starting or pole changing devices should not be wired between the converter and motor. For IT mains, switches are not permitted between converter and motor. These measures ensure correct operation, maintain protection and prevent equipment damage.

The 134F2975 frequency converter is built for industrial reliability with specified environmental tolerances. It operates at full load capacity up to 1000 m altitude without derating with 1 % derating applied per 100 m above this level up to 2000 m maximum. It handles displacement amplitude of 1 mm peak at 3 to 15.8 Hz and acceleration amplitude of 1 G from 15.8 to 150 Hz.
