PLZ-series (including PLZ-5WH2 series) have the RC damping circuit in parallel with the DC INPUT terminals to avoid negative effects such as an inductance component of the load cables or an oscillation caused by the parasitic capacitance of the FET in the power unit.
The damping circuit for PLZ-5WH2 series is expressed as C + R and the values are as follows:
PLZ1005WH2: 0.47 μF + 16.5 Ω
PLZ2005WH2: 0.94 μF + 8.25 Ω
PLZ4005WH2: 1.88 μF + 4.125 Ω
PLZ12005WH2: 5.64 μF + 1.375 Ω
PLZ20005WH2: 9.40 μF + 0.825 Ω
