Bipolar 2-4 Quadrants Power Supply include the D4, D2, D2C series.
D2 Power Supplies series are built to meet particular testing needs in many sectors, for example to obtain charging and discharging profiles of batteries in a cyclic way without having to disconnect the battery from the power supply to connect it to a load or for automotive tests or in all those applications that require a voltage generator and an electronic absorber in a single instrument.
D2C series are Power Supplies with 2 opposing quadrants to obtain the supply of current with inverted poles. Indispensable in certain galvanic or chemical processes that require cyclical inversion of the power supply polarity of the process electrodes so they eliminate the problem of maintenance of contactors that carry out polar exchange in a mechanical way. They are also suitable for testing direct current motors to reverse the direction of rotation in the absence of sparking created by an electromechanical switch or for managing direct current electric motors that must be controlled in both directions.
The Bipolar 4 Quadrants Power Supplies can source or sink current both in
the positive quadrant and in the negative quadrant.
