Matrix MPS-3003H-3 power supply

This 3 channel power supply from Matrix has a decent build quality and an attractive price. Using a button, CH1 and CH2 can be combined into series or parallel to make 60V / 3A or 30V / 6A. The earth terminal is seperate, which also allows you to make a symmetrical power supply. CH1 and CH2 can be switched on/off using seperate buttons, while CH3 always provides 5V (up to 3A).

The voltage can be set in steps of 10mV, the current can even be set in steps of 1mA.
