Description The Simplex Polaris 2.0 is a highly standardized, advanced design, Load Bank Series, covering the small KW ranges, 5-150kw, at common 60 and 50 hertz low voltages. The Polaris is intended for permanent installation outdoors or indoors. The Polaris carries the UL and UL-C Listing. The product is designed for local or remote control, with standard digital HMI which accepts a sophisticated optional automation package. The Polaris 2.0 is highly standardized into ve frame sizes. Within a frame size, the unit can be easily programmed to a discrete KW rating based upon the standard load step resolution of the frame. Programming is easily accomplished via the standard touchpanel HMI. The Polaris 2.0 is digitally controlled via an on-board PLC. Control is via a 4-inch TFT color touchpanel HMI. Remote control is via RS-485, shielded/twistedpair network cable (1000m). Local and remote HMI is housed in a weather/ tamper-resistant, lockable enclosure. Basic unit is setup for manual control. Digital control is via direct numeric 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. 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. Load levels, high/low set-point bandwidth, and time delays are easily user programmed on the touchpanel. With the automation option, full display of load bank electrical values (V-A-Hz-KW) is also provided. Options are available for load bank integration with Building Automation Systems via MODBUS RTU RS-485 or MODBUS TCP.
