Product Description:
The 137N4519 Frequency Converter is designed for reliable performance in demanding operations. It operates on a three phase supply range of 525 to 600 VAC. The device delivers a rated power capacity of 37 kW. It features a compact IP20 chassis design that ensures efficient integration across applications.
This 137N4519 frequency converter from Danfoss provides multiple performance advantages supported by advanced technical specifications. It offers a continuous current rating of 54 A under high overload conditions. Its intermittent current rating reaches 78 A that ensures stable output during peak demands. The device supports a rated motor frequency of 50 or 60 Hz. The output voltage control ranges from zero to one hundred percent of supply voltage. The output frequency range is adjustable between 0.2 and 132 Hz with an extended option from 1 to 1000 Hz. The ramp times are adjustable from 0.02 to 3600 seconds. This enables smooth acceleration and deceleration across operations. The switching on the output is unlimited to ensure reliable operation without restrictions. The device provides a nominal power capacity of 45 kW at 110 percent load. At 150 percent overload, the rated power remains 37 kW. The coated PCB construction improves durability against dust, humidity and environmental stresses.
The 137N4519 frequency converter delivers an apparent power rating of 51.8 kVA under high overload conditions. The power loss under normal overload reaches 900 W while under high overload it remains 740 W. The height of the chassis of the converter is 550 mm that allows compact mounting in restricted spaces. The integrated brake chopper ensures effective braking performance in dynamic operations. The graphical local control panel provides easy parameter setting and real time monitoring.
