Page 11: Chapter 1 General Information
ARRAY 366XA is a series of programmable switching-mode DC power supply with stable voltage and constant current. The excellent line and load regulation, extremely low ripple and noise make it well suited as a high preference power system. 366XA, as a kind of high-efficient switching-mode supply, features wide supply input voltage from 100-240AC, high power factor and a minimum output of 0V. -
Page 12: Installation
Keep the original packing materials in case the power supply has to be returned to Array for repairing in the future. If you return the power supply for service, please attach a tag identifying the owner and model number. A brief description of the malfuction is also needed. -
Page 13: Rack Mounting
the over-temperature protection may take effect, depending on the input voltage and output power. A brushless fan is used to cool the power supply by drawing cool air through the two sides and exhausting the heat through the fan outlet on the rear panel. Sufficient space must be left at the rear and two sides of the cabinet for air circulation when the power supply is installed. -
Page 14: Chapter 2 Initial Operation
Preliminary Checkout ARRAY 366XA power supply can be used from a rated 100 V to 240 V single phase AC power source at 47 to 63 Hz. There is an indication below the AC power inlet on the rear panel showing the rated input voltage set for the power supply at the factory. -
Page 15: Fuse Replacement
Fuse Replacement 1 Replace the fuse Step 1: Remove the fuse-holder below AC power inlet. Step 2: Replace the fuse with the correct one that meets the requirements. Step 3: Put back the fuse holder. For 115V AC operation, 10AT fuse must be used; For 230V AC operation, 6AT fuse must be used. -
Page 16: Power-On Checkout
Power-On Checkout The power-on test includes an automatic self-test that checks the internal microprocessors and a system self-test after the power supply is turned on, and examines the information relate to self-test process shown on the front panel. You will observe the following sequence on the display: 1. -
Page 17: Output Checkout
Output Checkout The output checkout is to ensure that the power supply develops its rated outputs and properly responds to various operations. Specific steps are shown as followings: Voltage Output Checkout 1. Turn on the power supply. Press the “Power-on” button, and finish the power-on checkout. Usually the power supply will go into the power-on / reset state automatically. - Page 18 Current Output Checkout 1. Turn on the power supply. Press “Power-on” button and finish the power-on checkout. Usually the power supply will go into the power-on / reset state automatically and the “OFF” annunciator in the lower right corner of the LCD turns on. Both the voltage value and current value are 0.
- Page 19 6. Ensure that the current can be adjusted from 0A to the maximum rated value. Adjust the knob until the ammeter indicates 0A and then until the ammeter indicates the maximum rated value. If an error has been detected during the output checkout procedures, the ERROR annunciator will turn on.

normal range. The Power Supply Calibration Because various factors may cause the reduction of the power supply’s output precision after it has been used for a period of time, the user should calibrate the power supply’s output to make the output return to the previous precision. But it is suggested that the power should not be calibrated frequently. - Page 28 In this mode, three voltage points: 0.5V、22V、34.5V should be calibrated. 3.1.1 Wiring OUTPUT KEITHLEY 2000 366XA SENSE 3.1.2 0.5V Calibration Press “Enter” key, you will see the following figure in the display: Input the value you read from KEITHLEY 2000, which is retained to four decimal places.

Page 32: An Introduction To The Scpi Language
An Introduction to the SCPI Language SCPI (Standard Commands for Programmable Instruments) is an ASCII-based instrument command language designed for test and measurement instruments. The detailed techniques used to program the power supply over the remote interface are introduced in the following sections. SCPI commands are based on a hierarchical structure, also known as a tree system. -
Page 33: Command Format Used In This Manual
Command Format Used in This Manual The format used to show commands in this manual is shown below: CURRent {<current>|MINimum|MAXimum} The command syntax shows most commands are the mixture of upper- and lower-case letters. The upper-case letters indicate the abbreviated spelling for the command. -
Page 34: Command Separators
Command Separators A colon “ ：” is used to separate a command keyword from a lower-level keyword as shown below: SOURce:CURRent:TRIGgered A semicolon “ ；” is used to separate two commands within the same subsystem as shown below: SOUR:VOLT MIN;CURR MAX The following two commands have the same effect as the above command. -

Page 38: Rs-232 Interface Commands
Some of them are the SCPI-confirmed commands, and some are the device-specific commands. It is unnecessary to differentiate them when using ARRAY 366XA. Using the APPLy Command The APPLy command provides the most straightforward method to program the power supply over the remote interface, such as to control one output or triple outputs of power supply, and to read the immediate output value of each supply. -

For the setting range, please consult the relevant current parameters listed in the table of “Programming Ranges and Output Identifiers” section. When the voltage and current are set, the “DEF|MIN|MAX” represents the default value, the minimum value and the maximum value respectively. -

Page 59: Chapter 6 Tutorial
Chapter 6 Tutorial Tutorial The ARRAY 366XA is a high performance instrument capable of delivering clean dc power. But to take full advantage of the performance characteristics designed into the power supply, certain basic precautions must be observed when it is connected for use on the lab bench or as a controlled power supply. -
Page 60: Unregulated State
Figure below shows the operating modes of the three outputs of the power supply. The operating point of one supply will be either above or below the line RL = RC. This line represents a load where the output voltage and the output current are equal to the voltage and current setting. -
Page 61: Connecting The Load
And the noise across the output terminals is of very low value in the ARRAY 366XA. The noise from the terminals to earth ground can be a problem for very sensitive circuitry that is referenced to earth ground. When a circuit is referenced to earth ground, a low level line-related AC current will flow from the output terminals to earth ground. -

Page 63: Reliability
Series operation of two or more power supplies can obtain a higher voltage output than that is available from a single supply. Series connected power supplies can be operated with one load across power supplies. The power supply has a related internal protection function so that if operated in series with other power supplies, damage will not occur when the load is short-circuited or the series-wound power supply are not turned on simultaneously. -
