This new laboratory power supply for symmetrical, that is, positive and negative output voltages, has stepless voltage regulation. For this purpose, three output sockets are located on the front panel. The central socket functions as the centre tap (0) and the output for the negative socket can be
up to -15V DC and for the positive socket up to +15V DC respectively. If the load is connected between the + and - poles, the output can be up to 30 V. In addition, this device has a 5 V / 0.5 A fixed voltage output. Therefore the device is ideal for use in training, and useful applications can also be found when explaining DC polarity or electroplating.
