Description
MARGEN Model MX-R1000 is a state-of-the-art, high capacity resistive load bank system intended for testing and routine maintenance of standby generators, UPS, or other AC power sources. Designed for outdoor installation, the load bank features vertical hot-air discharge to keep the installation footprint to a minimum. The load bank is digitally controlled via an on-board PLC with a colour touchscreen display and includes standard digital monitoring with test data capture to a USB drive
This load bank features a modular design with common sub-assemblies which improves quality and shortens lead- times. Quick shipping is available on various models such as 500 KW, 750 KW, and 1000 KW sizes.
The load bank enclosure is rated NEMA-3R and is suitable for permanent outdoor installation. The cabinet is constructed of heavy gauge steel with a durable polyester powder coat finish. The cabinet has hinged access doors with lockable latches. Cooling air is drawn in from the screened intake sides and the hot air exhaust is directed vertically upward through a stainless steel gravity louver. Forklift channels are included in the base for easy positioning and placement. The load bank incoming power connections are made inside the main cabinet directly to copper bus bars.
The load bank control power is provided from a standard internal control power transformer which derives power from the input load bus voltage. This eliminates the need to run a separate 120 VAC utility feed to the load bank which can save significant time and cost.
MARGEN’s proprietary resistor load elements provide the necessary power loading for each individual load step. The resistors are constructed from precision nickel-chromium resistance alloy and are fully supported within the air stream by stainless steel rods which are insulated with high-temperature refractory ceramics. Heavy-duty, PLC controlled magnetic contactors provide load application of each load step.

Standard Digital Load Controls
The load bank is digitally controlled via an on-board PLC with colour touchscreen display and includes standard data monitoring (Voltage, Current, KW, and Frequency) with test data capture to a USB drive. The load bank can be operated in manual, automatic, or multi-station mode. Multiple load banks can be daisy-chained together and run from a single controller for higher capacity testing. The digital controller includes a wide range of safety circuits including cooling- air loss, over-temp, over- voltage/under-voltage, and load dump. All load is automatically removed and locked-out in the event of a safety circuit trip. A hard-wired Emergency Stop switch is also included.
The load bank digital controller can be daisy-chained up to 40 units (up to an astounding 8000KW), all controller by single-point digital controller with full monitoring (volts, Amps, Frequency, KW) with data logging and acquisition.
This model is the new industry standard for 500 KW to 1000 KW permanently mounted load banks and is backed by years of expertise in load banks since 1976.
