Atlas-Megawatt Digital 1000KW Load Bank with Data Acquisition Overview • High capacity, 1000kw • Dual voltage: 208-240/416-480vAC • Digital load control, 5kw resolution • Touchscreen operator interface • Data acquisition and recording • Network units to form large systems Description The Simplex Atlas-Megawatt is an ultra large capacity, high performance Portable Load Bank designed to provide the manufacturers, distributors and users of large AC generators and UPS systems with sophisticated testing capability. The Atlas-Megawatt provides 1000kw of resistive load at both 240V and 480V, 3- phase. It can be applied at any AC voltage to 480VAC, 50-60-400 Hertz, single or 3-phase. Load step resolution is 5kw. The Atlas-Megawatt is a totally self contained testing system. It includes all resistive load elements, load control devices, load element circuit protective devices, connection cable set, cooling system, malfunction detection system, control power supply and test instrumentation. Atlas-Megawatt with optional weather resistant configuration and optional toggle switch control. UL Listed Digital Control: PLC based control with 8-inch color TFT touchscreen interface. MODBUS over RS-485 network communication. See page 3. Instrumentation: Digital power transducer with Ethernet communication to digital controller. Data display on touchscreen. Data acquisition and recording. See page 3. Load Elements: Simplex “Powr-Web” chromium alloy, open wire, continuously supported, power resistor. See page 2 for details. Load Control: 3-Pole contactors. Load Element Circuit Protection: Branch circuit fuses. One set of fuses each 50kw branch. Fuses are current limiting type, 200KAIC, 600V. Cooling System: 3-phase, direct-drive fan, 26,000 CFM. Malfunction Detection System: Protection against fan failure, high exhaust air temperature, high intake air temperature, over voltage and fan reversal. Exhaust air temperature displays on screen. Control Power Supply: Dual voltage control power transformer with supply power switchable to internal (generator) or external. Touch Screen: Easily removable from panel. Connection: 12’ connection cable set including 3-phase power cables, ground cable, stored in rear compartment.

Digital Load Bank with Data Acquisition 1000KW • Page 2 Powr-Web Resistive Load Element Description Simplex Load Banks utilize “PowrWeb” load elements. 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 element by high temperature, ceramic clad stainless steel rods. The “Power Webs” are assembled into discrete trays which are assembled in a vertical...
