Technical Details
Power consumption
The powers inrush current depends on the mains voltage and switch on timing
with the mains phase. In a worst-case scenario (Phase 90 degrees and 130VAC),
the current peak can reach as high as 20A (Figure 35). Eltorque recommends
having a skilled electrical engineer calculate the appropriate number of actuators
on a specific loop or UPS. Eltorque can also assist with some experience data on
request.

Surface treatment
Eltorque actuators have been designed to withstand harsh environments. All
products have undergone and passed severe 700 hrs. salt mist tests. Different
types of surface treatment have been used. Aluminum parts are typically
anodized or CED coated, and steel parts are treated with Dacromet and painted.
Communication interface
The Eltorque communication interface consists of three main modules:
Power supply
Motor control
