Product Description:
The 195N1088 Frequency Converter is designed to provide efficient and precise control of three phase standard AC motors. It offers variable speed control by converting AC voltage to DC and then back to AC with adjustable amplitude and frequency. This unit is ideal for applications that require flexible motor speed control.
The 195N1088 frequency converter from Danfoss operates with an input range of 3 x 380 – 480 V at 50/60 Hz with a maximum input current of 10.6 A. The voltage is phase-to-ground with a maximum rating of 300 V. For output, it supports a frequency range of 0 – 1000 Hz and provides 12.0 A current with 8.3 kVA power. The unit features a chassis rated at IP20 that ensures adequate protection for the system. It can operate in ambient temperatures up to + 45 °C (113 °F). It also complies with UL and CE standards. The unit can handle two connections at the supply input (L1, L2, L3). This frequency converter precisely regulates motor speed by transforming fixed mains voltage and frequency into variable amplitude and frequency outputs. It employs pulse width modulation (PWM) technology to ensure efficient power conversion and optimal motor performance across varying load conditions.
The 195N1088 frequency converter supports a supply frequency of 50 - 60 Hz ±3 Hz with a maximum imbalance of ± 2 % of the rated supply voltage. The true power factor at rated load is 0.90 and the displacement power factor is near unity (> 0.98). It supports a maximum short circuit value of 100,000 A that ensures high resilience to electrical faults. These features combined allow for precise motor control, efficient energy use and strong protection against electrical disruptions.
