1.4 Connect Power
The power supply supports a variety of AC line power input values. For each
line voltage, the rear panel voltage selector settings are dierent, as shown in
table 1 below.
Table 1: AC input line power specications
AC power input Voltage selector

100 VAC ± 10%，50 - 60 Hz
120 VAC ± 10%，50 - 60 Hz
220 VAC ± 10%，50 - 60 Hz
230 VAC ± 10%，50 - 60 Hz
Please connect the external AC power carefully using the steps below:
1. Check the input power
Make certain that the AC line power to be connected to the instrument
meets the requirements outlined in Table 1.
2. Check the voltage selector on the rear panel
Make certain that the voltage selector setting on the rear panel of the
instrument matches the actual input voltage.

9 User Manual EAR99 technology subject to restrictions on copyrights page.
3. Check the fuse
When the instrument leaves the factory, the specied fuse is installed.
Please check whether the fuse matches the actual input voltage
according to the "Input Power Requirements" on the rear panel of the
instrument.
4. Connect the power
Connect the instrument to AC power supply using the power cord
provided with the accessories. Then press the button to turn on
the power.
WARNING
Before switching the input power supply voltage, please disconnect the
power supply before setting the voltage selector to the appropriate setting.
WARNING
To avoid electric shock, make certain that the instrument is correctly
grounded.

1.6 Output Inspection
1. Check the output voltage
• Turn on the power and make sure the channel current setting is not zero
when the instrument has no-load.
• Press on/o button, the supply should be working in constant voltage
(CV) mode. You can set the voltage range of the T3PS16081P by
adjusting the voltage setpoint from the minimum (0 V) to the maximum
value (16 V) and the voltage range of the T3PS30051P by adjusting the
voltage setpoint from the minimum (0 V) to the maximum value (30 V).
2. Check the output current
• Turn on the power and make sure the voltage setting is not zero.
• Connect the output terminals (short) with an insulated wire that can handle
10 A or more (18 AWG single core, for example).
• Activate the output by pressing the on/o button. The low impedance
(shorted) output will cause the instrument to enter current control (CC)
mode. You can set the current range of the T3PS16081P by adjusting the
current setpoint from the minimum (0 A) to the maximum value (8 A) and the
current range of the T3PS30051P by adjusting the current setpoint from the
minimum (0 A) to the maximum value (5 A).

1.7 Fuse Replacement
The specications of the fuse are relative to the actual input line voltage, shown
in the table below. You also can refer to the rear panel “input power
requirement”.
To replace the fuse, please follow the steps below:
1. Turn o the instrument and remove the power cord.
2. Insert a small straight screwdriver into the slot at the power socket
and gently pry out the fuse seat.
3. Adjust the power voltage selector manually to select the correct
voltage scale.
4. Take out the fuse and replace it with the specied fuse (for the
corresponding relationship between the AC input voltage and fuse
specication, refer to the “input power requirement” at the rear panel).
5. Re-insert the fuse holder into the power socket (please pay attention
to the directions).
WARNING
To avoid personal injuries, unplug the power supply before replacing the
fuse. To avoid electric shock or re, select the proper power supply
specication and replace only with the proper fuse.
