K595

55.5 kW Load Bank

Great for Testing

The K595 is used to test small generator sets, Uninterruptible Power Supply (UPS) units and other AC sources. It is intended for use onsite, in industrial and test lab environments.

Weight(121.6 kg) 268 lbs.
  • Great for small generators, UPS’s, and other AC power sources
  • 240/480 VAC 3 phase capacity is 55.5 kW

  • Mobile, with casters

  • No “cool-down” period after operation
  • Capable of Single Phase Testing at wide range of voltages

Product Details

  • The K595 is a 55.5 kW, 240/480 volt, 3-phase, 60 Hz load bank. The K595 is a wye-connected unit. This makes it more versatile as it can also be used for testing 120 volt, single-phase, power sources up to 41.6 kW.
  • This unit is engineered for fast and accurate testing. It is equipped with a large, easy to read analog voltmeter and ammeter. Load connections are made quickly and easily at the bus bars located behind the access door on the front of the unit.
  • The K595 incorporates industrial type contactors for application and removal of loads. They are positioned in an area that is isolated from the high heat generated by the resistive elements for improved reliability.
  • Load elements used in the K595 are made of a corrosion resistant material and are specially wound to support their full length for long and reliable operation. The load elements are engineered to operate at one half (or less) of their temperature rating, which is the main reason why a “cool-down” period is not required after load bank operation.

  • The K490 resistive load elements are at the core of the load bank system. To ensure years of reliable operation, the elements in the K490 operate
at only 1/3 (or less) of their maximum temperature rating, eliminating
the need for a “cool-down” period after operation. The load bank also includes over-temperature protection.
  • The K490 is simple to use. It does not require tools. Electrical connec- tions are made on the front of the unit using hand-tightened terminals. Banana jacks are standard for connecting hand-held multi-meters. The multi-meter allows voltage, current, or frequency monitoring.
  • With logically arranged controls, this load bank is intended to be an essential piece of test equipment used by field service personnel. Its reliable design, compact frame size, and light weight define the K490 as the “load bank of choice.”
