K-1000 AC Load Bank (Resistive/Capacitive)

A RCD (resistive/capacitive) generator load bank is non-linear load bank. The electronic and non-linear loads simulated by capacitive load banks are typical of the Telecommunications, Computer or Uninterruptible Power Supply (UPS) Industries.

Test of output and power quality for power supply is significant to ensure that power supply will work in critical situation to support loads without any pollution to power grid. The ideal solution is combination of both resistive and capacitive elements in one load bank package.
