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,
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.
