2.6 Installing
2.6.1 Preparation For Use
(1) Ensure the Power Supply is connected to the AC line input that meets the specification.
(2) The instrument must be installed in an area with good air circulation to avoid the internal temperature getting
too high.
(3) For indoor use only, ambient temperature 0°C to 40°C.
2.6.2 Requirements of Input Power
Please pay attention to the following items for FTP3000 series power supply input connection:
①Single phase AC input: 190VAC~265VAC, 47~63Hz;
②The AC input power cord is a 3-core cable with grounding connection, DO NOT operate the instrument if there
is no proper socket;
③There is 1PCS AC input power cable included with the accessories, which should be compatible with your local
electric voltage. Contact Faithtech agent or after-sale service immediately if you find the input cable is not
matching with the power supply AC input terminal.
----------------------------------------------------------------------------------------------------------------------------
The instrument provides mainframe grounding connection via 3-core power cable. Make
sure there is proper ground connection in applying socket before operation. Under no
circumstances shall this DC Power Supply be operated without an adequate ground
connection.
----------------------------------------------------------------------------------------------------------------------------
2.6.3 Power ON Self Check
When powered on, the power supply will conduct self check, the check process and results will be displayed on
the screen, such as below:
Figure 2-5 FTP3000 Power ON Self Check
The power supply will enter MAIN PAGE if all checking results are OK, otherwise it will wait for 3 seconds before
entering MAIN PAGE.
If there is FAULT during power supply power on self check, please refer to “Table 5-2 Power On Self-Check Fault”.

____________________________________________________________________________

2.7 Connection
2.7.1 Output Connection
The device under test positive and negative input terminal is connected to the “+” and “-” output terminals on the
front panel of the power supply respectively. When connecting, pay attention to the wire diameter, length and
polarity of the output cable. To prevent the wire diameter from being too small to affect the test accuracy and
generate large heat to cause safety accidents, please refer to "Table 6-1 Recommended Wire Diameters for
Cables" for wire diameter selection.
Figure 2-6 Power Supply Output Connection
----------------------------------------------------------------------------------------------------------------------
The diameter of the wire connected to the load must be adequate so as to carry the
maximum applied current.
----------------------------------------------------------------------------------------------------------------------
2.7.2 V-Sensing Connection
There are two kinds of V-sensing: local V-sensing and remote V-sensing.
FTP3000 series power supplies are able to compensate for the voltage drop caused by output connecting cables.
For remote sensing, be sure to connect the power supply’s remote sense connector “+S” to the load’s positive
input terminal and the “–S” connector to the load’s negative input terminal. Do not reverse the connections.

3. Function Introduction
This chapter describes the main functions and characteristics of the power supply. Reading this chapter, you will
have a deeper understanding of FTP3000 series power supplies.
3.1 Local & remote operation mode
The power supply provides two operation modes: local operation and remote operation. In the local operation
mode, the user mainly operates through the keyboard and knob on the front panel, and checks the power status
through the LCD display; in the remote operation mode, the user mainly performs settings and operations via the
communication interface and programming commands.
Local operation mode
When the power supply is turned on, it operates in local operation mode by default. In this mode, the user
operates the power supply through the front panel keyboard and rotary knob. The LCD screen provides users with
display functions such as parameter viewing, measurement display and status indication.
Some parameters can only be set in local mode, including:
System language
Serial port baud rate and parity method
Key sound
IP address and subnet mask
Communication protocol
Remote operation mode
To enter the remote operation mode, please use the proper communication cable to connect the PC with the
power supply. The communication configuration parameters must be consistent with the control device settings.
Upon receiving the programming command, the power supply automatically switches to the remote operation
mode from local control mode.
In remote control mode, all other keys are disabled except key, and the power supply can only be
controlled by programming commands. Press on the front panel to return to local operation mode.
