Large Portable : Merlin

  Merlin 100KW-500KW Large Portable Load Bank Overview

Simplex Load Banks - Merlin Large Portable Load Bank

The Simplex Merlin is a dual voltage (240/480V - 100KW-400KW; 416/480V - 500KW), fine load step resolution, fully instrumented portable 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 in the 100KW-500KW range.

The Merlin is a totally self-contained testing system. It includes all resistive load elements, load control devices, load element circuit protective devices, connection cable set (100KW-400KW) or cam-type connectors (500KW), cooling system, malfunction detection system, control power supply and test instrumentation.

  Merlin 100KW-500KW Large Portable Load Bank Features

Load Elements
Simplex Powr-Web chromium alloy, open wire, continuously supported, power resistor.
System Controls
Digital Meter (100KW-400KW).
Fan Reversal, Load Voltage Selector, and Control Voltage Selector switches.
Operator indicator lights: normal operation, over-voltage, fan failure / over-temperature.
Master load toggle switch and load step toggle switches.
3-phase, direct drive fan, 6,000-8,000CFM (depending on load configuration).
