LOAD BANKS AND TESTING SYSTEMS FOR GENERATORS, GENSETS,
WIND/GAS/FUEL-CELL GENERATORS AND UPS
· To test and maintain electrical generators, UPS and battery systems
· To reduce CO2 emission avoiding wear on under-loaded diesel generators
· To prolong the life of electrical power systems and engines
· Meeting testing requirements for European and USA standards (ISO8528, IEC364-7-710, EN60034-9, NFPA70, NFPA110)
APPLICATIONS OF COUNTER WITH LOAD
· Manufacturers of power systems such as generators, UPS and battery systems for computerized testing
laboratory and end of line.
· Buildings, hospitals, places of public gathering, critical communications, security systems for computer
science and finance provided with emergency power systems : European and U.S. standards require that
these are undergo regular maintenance procedures doing load tests at least 50 % of the power
nominal and that the data is collected.
· Any generator at a fixed location : to avoid the common problem of "wet stacking" when the
diesel engine operates with insufficient load causing the accumulation of unburned fuel in the system
discharge that may interfere with the injectors , the valves of the engine and the exhaust system, including
turbochargers thereby reducing performance. The load can be achieved by providing appropriate
an additional load by means of a bank of resistive load with an automatic
load control; This increases the service life of the diesel engine up to four times and increases the
yield .
· UPS systems and battery power : the load banks maximize battery life by uploading and
downloaded regularly.

Load bank controller / data logger
The MC1 controller is made of a touch screen LCD display and a controller. It offers simple operation of the load bank start up, kilowatt selection and load bank status.
The unit automatically configures the load steps in the load bank to provide instant kilowatt response as selected by the Up/Down keys. Other features include load bank “system check”, which prevents loading in the event of fan cooling failure, fan reversal or high temperature. MC1 also features data logging function. The MC1 controller totally replaces outdated control devices such as toggle switches and push buttons.
