The Simplex Merlin is a dual voltage (240/480V), fine load step resolution, fully instrumented portable resistive load bank intended for shop or field use by engine generator dealers and service shops for maintenance, testing, and performance proving of engine generator sets, UPS, and other power systems up to 200-400 KW (depending on the model).

FEATURES

  • Load Capacity: Max capacity up to 200, 250, 300, 350, or 400kW at 240 and 480 VAC, 3PH, 60Hz. Capacity derates at other voltages.
  • Duty Cycle: Rated for continuous operation.
  • Load Step Resolution: 5kW minimum at 240 and 480 VAC, 3PH, 60Hz.
  • Controls: Master load toggle switch and load step toggle switches; Digital meter; Fan Reversal, Load Voltage Selector, and Control Voltage Selector switches; Operator indicator lights: normal operation, over-voltage, fan failure / over-temperature.
  • Merlin 200-300 Control/Fan Power: User selectable from internal 208-240V load or from external 115V 1PH 60Hz source – power cord included (see Options below).
  • Merlin 350-400 Control/Fan Power: User selectable from internal 3PH load or from external 3PH 230/460V source.
