Electra

Overview

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.
