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.
