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.

Intesys Load Banks are completely self-contained, freestanding units which include all resistive/inductive load elements, cooling system, overheat and fan fail detection system, load elements circuit protection, load control systems and devices, (optional) digital instruments for AC measurements, controllers and computer system+software for automatic testing and data logging

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 The MC1 controller totally replaces outdated control devices such as toggle switches and push buttons.
