Description High capacity load testing of generators, periodic reliability exercise of standby generators, regenerative power absorption of inertial motors with reverse power protection of generators and other load bank applications are achieved with the Simplex Neptune Load Bank. The unit capacity range of the Neptune is 200-650KW, resistive, unity power factor. Reactive units (inductive or capacitive) are also available. For unit loads in excess of 650KW, use the Simplex Mars (to 1250KW) or Saturn (to 3000KW). For loads less than 200KW, the Simplex Polaris (to 150KW) is available. The Neptune is a single or dual voltage load bank suitable for all common 60, 50, and 400 hertz voltages up to 600V. Cooling System: Using a very high volume forced air cooling system of 10,400 CFM or 13,400 CFM, air temperature rise is limited to the 150-200°F range. Features • Self-contained load and control system • Utilizes the proven Simplex “Powr-Web” load element (see page 2) • Branch circuit fuse protection of load elements • Digital load control (see page 4) • Comprehensive malfunction detection system • 150°C insulated power wiring; color coded • Plated bus bar • UL Listed • Type 3R, oversize control section with generous cable connection space • Vertical airow, exhausts hot air above level of personnel and away from buildings, pavement etc. • Modular enclosure design with separate and isolated control and power sections • Slide-out, tray mounted load elements • Highly standardized for quick turnaround, or highly customized for special requirements, based upon extensive product line spanning from 5KW to 3MW • Supported by comprehensive engineering and product support, including detail manuals, 24 hour eld service, availability of start-up • Comprehensive overload, short circuit and malfunction protection

200KW - 650KW 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 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 “stack.” Each tray...
