KD multi-channel series DC power supply uses digital encoders and the button control, which has the simple and convenient operation, safe and reliable features. And there are series and parallel output operations and triple-way adjustable control, that is, CH1 and CH2 output 0-30V while CH3 can output three voltage stalls: 2.5V, 3.3V and 5V. In addition, there is the output switch and the shutdown memory function. And the fine and coarse adjustments can be achieved by pressing the knobs. Furthermore, the knobs have 2 operating modes: the continuous adjustment and the lock adjustment, which can make the operation convenient and reliable, that is, the keyboard can be locked to avoid improper operation. Regarding interfaces, LAN, USB & RS232 are included with a wealth of SCPI instructions, which can provide the Labview driver and programming examples to facilitate engineers to set up the test system
quickly.
