Accessories for variable transformers, tracking controller
Description
Control unit for motor-controlled variable transformers
The REO control unit NLR 7000 is used for constant adjustment of voltage or power in variable transformers.
The REO Controller NLR 7000.1 -3 is an electronic controller for the following control options – all combined in one controller:
- NLR 7000. 1= Variable AC control
- NLR 7000. 2 = Variable DC control
- NLR 7000. 3 = Constant voltage +_ 10-30%
The control electronics of the NLR 7000 control the three-phase motor of the variable transformer for this purpose. Various applications are made possible through programming. The parameters are set via the LED displays – optionally also with remote control.
Benefits
- simple operation
- for voltage stabilizers or as current/voltage regulators
- horizontal or vertical mounting
