LC12DAL Control For WA……LCD Series Load Banks



Description

The LC12DAL controller is a portable processor capable of controlling one or more resistive or reactive load banks from a distance of up to 100m. Operating features include a four-line display  with simple step-by-step instructional prompts, display of load values such as kW, kVa, V, Hz, PF, Amps and load time. Choice of operation includes manual and automatic load routines. The automatic loading feature has loading routines with time duration and pause override function. Changes to a load routine such as load size and time, is possible at any time during a load test from the pause function key. The controller automatically tunes and corrects the load bank in the event of voltage or resistance fluctuation. The controller also ensures that the load bank is fully protected against over voltage or frequency, preventing the test to proceed. All functions are fully displayed, including warning messages, such as voltage exceeded, frequency incorrectly set, emergency stop, load aborted and cooling failure. 

The LC12DAL construction is made of solid aluminium extrusion with die cast corners, weatherproofed and sealed to IP55. The handle can be rotated and locked in any position to suit the user. Connections includes a 6 pin input connector, standard USB port for connection to a PC or Laptop, to obtain additional on-line graphics of actual load tests. Additional features of the controller includes adjustment of all the operational settings namely operating voltage, frequency, power factor, data capture printing intervals. Test routines are held in memory for repeated use.  Data captured includes all electrical values, such as phase voltage, line to line voltage, phase currents, line currents, frequency, kW selected, kW achieved, kVa, power factor and elapse time.

Safety features include load bank "System Diagnostics" to ensure that voltage and the operating current do not exceed the load bank’s designed rating. The LC12DAL controller is also available in a panel mounted version for test cell operations.
