K-1000 AC Load Bank (Rack Mounted)

Rack mounted resistive load bank is widely used in data center to simulate electric loads and dissipation of IT systems. These load banks are controlled by sectional steps with customized setting. Users could set power and time as per their needs with easy operation.

Load test using these rack mounted load bank will ensure the effective performance of power supply system, AC conditioning system, lightning protection systems, monitoring system, IT system of data center.
