Technical Data, Brake Chopper Bg2; Ambient Conditions - Keba ServoOne CM-P BG1 Operation Manual

NOTE:
In the overall axis group, a DC link capacitance of ≥ 100 µF/kW (for 3 x 400 V)
or ≥ 170 µF/kW (for 3 x 230 V), referred to the highest rated power that
occurs, must be provided. This capacitance is determined by adding together
the capacitances of the individual devices. The root mean square of the active
power for a load cycle is defined as the active power.

Climatic conditions
As per EN 61800-2, IEC 60721-3-2 class 2K3
In transit Temperature
Relative atmospheric humidity
1) The absolute humidity is limited to max. 60 g/m³. This means, at 70 °C for example, that the relative atmospheric humidity
may only be max. 40 %.
2) The absolute humidity is limited to max. 29 g/m³. So the maximum values for temperature and relative atmospheric humidity
stipulated in the table must not occur simultaneously.
3) The absolute humidity is limited to max. 25 g/m³. That means that the maximum values for temperature and relative atmos-
pheric humidity stipulated in the table must not occur simultaneously.
