6,250kVA Crestchic Load Bank | CR6.25

6,250kVA Crestchic Load Bank | CR6.25


  • Used, fully tested.
  • Crestchic
  • Model: CR6.25
  • Year: 2008
  • Resistive/Reactive Load Bank

  • The loadbank is an outdoor, transportable resistive/reactive unit for electrically load testing 380-480V A.C. 50/60Hz 3-phase power supplies with voltage tolerance of 5%.
  • The function of the loadbank is the dissipation of electrical energy which is transformed into heat by the resistive elements. This unit will produce 5000kW of real power dissipation at 480V full load.
  • The heat is removed from the loadbank by the fan(s) passing air over the resistive elements. It is essential the inlet and outlet grilles are free from any obstruction otherwise the loadbank will overheat.
  • Circuit Breakers and/or Fuses are fitted inside the loadbank for short circuit and over current protection.
  • Do not operate the Loadbank over the rated voltage or frequency as this may cause failure to the loadbank.
  • External Auxiliary Supply input 380-480V 50/60Hz. If this supply is connected select ‘External’ of the ‘Control Supply’ switch and also select the voltage range on the ‘Control Voltage’ switch of the connected supply. This will supply the cooling fans and the control of the loadbank. 125A 3-phase supply is required.
  • If no External Auxiliary Supply is connected, the ‘Control Supply’ switch must be in the ‘Internal’ position and again select the voltage range on the ‘Control Voltage’ switch of the connected test supply. If the control of the loadbank is derived from the test supply, should the voltage fall below 340V while under load the cooling fan(s) will stop, resulting in the load being dropped.
  • An 110V inlet socket is provided for internal lighting and anti-condensation heating. This circuit should remain live at all times whenever possible, to prevent condensation build- up inside the load module and the micro control chamber. If this is not connected the auxiliary supply is used to prevent condensation in the micro control chamber when switched on.
  • Load application is controlled from either the Hand Held Terminal (HHT) or a Laptop PC with Eclipse Software installed. For complete Micro (MCS) operating instructions please refer to ‘Eclipse AC Loadbank Operating Instructions for Windows PC’ or ‘Eclipse AC Loadbank Operating Instructions for HHT Controller’ enclosed in this manual.
  • A backup local KCS control system is provided with the loadbank for use if the other controllers are not available.
  • A set of three ammeters (1 per phase) and a voltmeter with phase selector switch is provided for local monitoring purposes.
