NOTE!
- Through the power contacts of the bimetallic overload relay circulates Direct Current
during the DC-Braking process.

3. TECHNICAL SPECIFICATIONS

The information below are referred to the data on table 1.
1) The max. current can be calculated by:
Imax= set value at P153[V]/value of the resistor [ohms].
2) The rms braking current can be calculated by:
t
I = I .
br
rms max
actuation times during the most severe 5-minute cycle.
3) The minimum resistor value of each shown model has been calculated so the braking
current does not exceed the maximum current specified in table 1. For this, following
parameters have been considered:
- DBW-01: rated line voltage = 480V.
- DBW-02: rated line voltage = 690V.
- Factory Standard Value of P153.
NOTE!
- For a complete description of the module DBW operation along with the CFW-09,
please, refer to CFW-09 User's Guide.
