Selection Guide

When choosing a load bank:

• Rated Power ≥ 1.2 × tested equipment rated power.

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

• Power Factor: 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

Q1: Can the load bank run continuously at full power?
Yes, with proper ventilation, it can sustain continuous full-load operation.

Q2: How often should maintenance be performed?
