Continuous Speed Controller DR

Description

The continuous speed controller DR individually adapts fan performance to suit the required conditions. The unit is activated modularly behind the dT100 or dT200 ventilation control. Selection is made on the basis of the sum of the total currents of all connected fans, plus a 30% addition.

Example: 2 x fans AV-400 = 2 x 0.95 x 1.3 (addition) = 2.47A
-> Selection 1 x speed controller DR-3
