Automatic Load Transfer Controllers ATS2.0 ENKO Electronic Control Systems - IZMIR / TURKIYE Automatic Load Transfer Switch ATS2.0 is a very versatile load ATS2.0 is a full Automatic Load Transfer Control Switch, which moni- transfer switch, intended to be used in most demanding applications. tors 3ph Mains Bus-Bar voltages and transfer the load, if any or all Can control pulse type breaker monitors Mains frequency for the same action. These units can be modules directly from its output used with any two voltage bus-bars, where the load is required to be controlled according to their availability. The control module also phase voltages go out of their respective set limits. The controller also monitors all three phases of the Generator bus-bar and take action accordingly. ATS2.0 is designed with highly functional capabilities where the user can interface with most demanding applications. The module can control MCB and GCB contactors as well as compact circuit breakers direct from its ports, where two independent signals are required for switching the breaker on and off. The module allows the user to start the generator for testing or periodical maintenance. While the generator is running, the load can be transferred between mains and generator bus-bars, using the switches on the front panel. If, during this phase, the mains voltage fails, the unit automatically switches to “Auto” mode and connects the Its built-in features make ATS2.0 a load to Generator output. perfect device for bus-bar control During operation, mains or generator phase voltages or frequency can and load management module, integrated with enhanced user both be displayed on the front panel, hence avoiding extra AC voltmeters to be used on the panel. All voltage values are displayed in True selectable functions. All unit parameters can be adjusted from the device configuration menu and all program parameter values can be seen on the controller display. The units can also be programmed to control the engine cool- grammed for many specific func- down function, hence allowing simple engine starter units to be used with small capacity generator sets.
