Chapter 1 General Introduction
1.1 General Introduction
The ARRAY 3600 Series Power Supply is a compact programmable DC power supply. It is
equipped with back-light LCD display, number keypad and rotary knob which make it much
easier to use. It can be operated at constant voltage mode or constant current mode. Pro-
gramming feafures include over-current protection, maximum output voltage and power
limitation, and 10 parameters storage. It is an essential instrument for scientific research,
education, service and so on institutions.
