Description

The Simplex NorthStar Portable Digital Load Bank is speciﬁ cally designed for the Canadian Market by providing 600v capability in an ultra-compact, lightweight, versatile test instrument WHICH CAN BE NETWORKED FOR HIGH AGGREGATE KW. The NorthStar is rated 150kw in steps of 5kw. It is suitable for testing engine generators, wind generators, UPS systems, ground power units, auxiliary power units, static inverters or virtually any other AC power source on the production line, in the service shop or in the ﬁ eld.

The NorthStar is a digitally controlled load bank with network capability. All control is via a hand-held touchscreen controller connected to the load bank via a supplied RS-232 network cable. The load bank includes a digital power transducer with meter displays on the touchscreen. Load is applied via a screen keypad. Any number of NorthStar Load Banks can be networked together via RS-232 cables connected from the “out” connector on the ﬁ rst unit to the “in” connector on the next, and then “out-to-in” in succession until the desired number of units are connected. All control and metering is provided from a single hand-held controller. All instrumentation values for the total network are summed and displayed on the master controller.

The NorthStar is highly portable and easily transported to the job site. The Load Bank includes casters, lifting and moving handles. Power connections are plug-in to Cam-Lok connectors. Control and cooling fan power is obtained from a common 115v, 15A outlet via the included connection cord.
