Description Simplex Merlin Load Banks are the new standard for advanced design in Portable Load Banks spanning the capacity range of 100–400KW. The Merlin is a dual voltage (240/480v), ne load step resolution, fully instrumented Portable Load Bank intended for small-medium capacity shop or eld 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 50–400KW range. The Merlin is available in discrete model sizes of 100KW, 150KW, 200KW, 250KW, 300KW, 350KW and 400KW. The Merlin control panel includes test instrumentation, load application switches, operation indicator lights and fan/control power switch. The Load Bank includes rugged “Powr-Web” load elements, load control contactors, branch circuit fuse protection of the load elements, high temperature power wiring, cooling fan with circuit breaker, control power fuses. The Load Bank is protected against fan failure, high intake air temperature, high exhaust air temperature, and overvoltage. The unit includes a 12’ connection cable set. Merlin Load Banks are built on a formed and welded steel chassis that is both rugged and lightweight. For exible portability, the Merlin includes casters, lifting eyes and forklift channels. Airow through the unit is horizontal with cooling provided by a cast aluminum airfoil type shrouded propeller fan. Features • Exceptionally rugged, all welded, formed steel chassis • Hinge-open control section door • Lifting eyes, forklift channels and casters • Moving handle • “PowrWeb” Load Elements • Branch circuit fuse protection

100KW - 400KW Load Bank • Page 2 Powr-Web Resistive Load Element Description Simplex Load Banks utilize the “PowrWeb” Load Element (a UL Recognized Component). The “Powr-Web” is an advanced design, air-cooled power resistor specically designed for application to load bank systems. The “Powr-Web” is conservatively operated at half the maximum temperature rating of the alloy and features a short-circuitsafe design based on continuous mechanical support of the resistor by high temperature, ceramic clad stainless steel rods. Construction • Precision calibrated to specic ohmic value • All load elements...
