The RC series dv/dt filters combine appropriate values of inductance, capacitance and resistance to form a filter which reduces dv/dt and peak voltages from the PWM voltage waveform. This combined with a 3% impedance reactor, that will reduce motor heating harmonics, will significantly increase the life of the motor. Long lead length motor drive applications can experience motor terminal peak voltage spikes twice the DC bus voltage and higher. Therefore motor terminal voltage peaks of 1200 VAC for 480 VAC drives and 1600 VAC for 600 VAC drives are not uncommon. The highest peak voltages will typically occur in lower HP applications.

HPS DV/DT Filter, Series: RC Series, 480/600 VAC, 8 A, 3 ph, 3 mH Inductance, 3 % Impedance, 7.4 in Height, 9 in Width, 6.18 in Depth, Base/Panel Mounting

• They should always be installed next to the IGBT variable frequency drive
• Typical installation applications include production process lines, conveyor systems and deep wells
• dv/dt filters offers the motor protection from voltage spikes while power by a variable frequency drive while lowering the motor's operating temperature and audible noise
• 50/60 Hz frequency rating
• Noise level between 58 to 75 dBA
