700KW - 1250KW Load Bank Description High capacity load testing of generators, UPS, and other AC power sources; periodic reliability exercise of standby generators; automatic load leveling and minimum load regulation; regenerative/ reverse power protection and other load bank applications is possible with the Simplex Mars Version 2.0 Load Bank Series. The Simplex Mars Version 2.0 is a highly standardized, advanced design, digitally controlled Load Bank Series spanning the 700-1250kw range at common 60 Hertz and 50 Hertz low voltages. Mars V2.0 Is a standard inventory item with versatile control and application possibilities. Mars V2.0 is intended for outdoor or indoor installation. As with all Simplex Planet Series Load Banks, the Neptune is UL/CUL Listed. Mars V2.0 is digitally controlled via an on-board PLC, which accepts standard programs for manual, automatic and multi-station control, as well as data monitoring and data acquisition. V2.0 is designed for local or remote control, including multi-station control, using a standard digital, color touchscreen HMI. Remote control connection is simplified through use of RS-485 over shielded/twisted pair network cable (1000m). Local/remote HMI is housed in a weather/tamper resistant, lockable enclosure. Basic V2.0 is setup for manual control via direct numeric keypad entry. A comprehensive automation option is available which allows automatic load regulation via KW sensing such that the load bank automatically maintains a constant load on the generator. Load level, bandwidth, and timing are user programmable from the touchscreen. This function can be used for minimum loading to prevent wet-stacking and other low load issues, engine optimum loading for emissions control and for regenerative power protection. This function can also be used to stabilize voltage and frequency transients. With the automation option, full display of load bank electrical values (V-A-Hz-KW) is also provided on the touchscreen, with MODBUS registers provided for remote indication and data acquisition. Options are available for Load Bank integration with Building Automation Systems via Modbus RTU RS-485 or Modbus TCP.

700KW - 1250KW Load Bank  •  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 specifically 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 “stack.” Each...
