Common Questions & Answers
Q1:What is the maximum power output of this load cabinet, and what is its minimum adjustment range?
A:Rated total power: 3 kW; minimum step increment: 500 W; allows configuration of load powers in multiples of 500 W, ranging from 500 W to 3000 W.
Q2:Can the equipment operate continuously 24/7 without stopping?
A: Supports continuous 24/7 online operation; however, ensure proper environmental ventilation and do not obstruct the air intake or exhaust vents; maintain the ambient temperature between 10–50°C.
Q3:What are the installation methods?
AStandard 4U rack-mountable; can also be placed directly on a work surface; includes carrying handles and foot pads.
Q4: The output is a C20 socket – what does this mean?
A:C20 is an industrial power socket designed for C19 plugs, featuring three independent socket outlets for connecting external test equipment.
A: This model does not have built-in load protection; an external circuit breaker or protection device must be installed during use to prevent operation under excessive power load.
