Digital Load Bank with Data Acquisition 450KW - 700KW Overview • High capacity, 450-700kw • Dual voltage: 208-240/480vAC • Digital load control, 5 kw resolution • Touchscreen operator interface • Data acquisition and recording • Network units to form large systems Description The Simplex Electra is a very 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. Electra Load Banks feature digital controllers with network control and data acquisition capability. Operator interface is via touchscreen. Load control is via screen keypad. All electrical values display on the screen and are recorded by the system for future data retrieval. Any number of Electra and dynaMITE Load Banks can be combined for large system capacities and networked for central control and data acquisition. The Electra Series comprises models rated 450-500-550-600-650-700kw of resistive load at both 240V and 480V, 3-phase. It can be applied at any AC voltage to 480V AC, 50-60 Hertz standard, single or 3-phase. Load step resolution is 5KW. Load Control: 3-Pole contactors. Features UL Listed: File Number E151624. 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 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, 12,500 CFM. Malfunction Detection System: Protection against fan failure, high exhaust air temperature, high intake air temperature, overvoltage 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: “Cam-Lok” type power connections.

Digital Load Bank with Data Acquisition 450KW - 700KW • 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...
