Selection Guide

When choosing a load bank:

• Potencia nominal ≥ 1.2 × tested equipment rated power.

• Voltage Level must match system (300–380V standard, custom for 400/415/480V).

• Factor de potencia: choose RL load bank if your DUT (device under test) involves inductive / capacitive behaviors.

• Environment: outdoor use requires higher IP protection and enhanced cooling.

FAQ
