First use
Connecting power
-
input power demand
The details of input power should refer to chapter IV Performance Indicators. -
check the fuse
The proper fuse has been installed when the instrument is delivered. Please use the correct fuse model before startup. -
Connect power supply line of instruments
Use the power cord supplied by the attachment to connect the instrument to the AC power supply.
In order to avoid electric shock, please confirm that the instrument has been properl grounded.
Power-on check
Press the power switch front panel, connect the power. The back light of
ON/OFF key displays the red. The power output is in the off status. Press
ON/OFF key and the back light of ON/OFF key displays green. The power has
opened output.
Hint: please restart after shutdown. Please guarantee the interval of two
startups is larger than 5s.
Output check
The output check may ensure the instruments to correctly respond to the
operation of front panel and output the rated value. The output check includes
the voltage output of channel load and the current output of short circuit.
-
Output switch
To open the power output, press .on/off. key and the back light will turn to green. And then press the key to close the output and the back light will turn to red. -
voltage output check
- When the instrument is in empty load, open the power key and confirm the constant current of current knob is 0;
- Press ON/OFF key and open the output. When the back light turns to green, the channel is in constant voltage output status (CV light is on). Check whether the voltage is adjusted to the maximum rated value from 0.
-
Power output check
- Open power key;
- Adjust the power knob to make the power output voltage as 3-5V and then press ON/OFF key to cut the output;
- Use one wire to connect the output terminal of front panel;
- Press .ON/OFF key to open the voltage.
When the back light turns to green, the channel will be in constant current output status (CC indicator is on). Check whether the current is adjusted to the maximum rated value from 0. Chapter II Operating specifications
Operating specifications
Constant voltage output
The power supply provides two kinds of power output modes: constant voltage output (CV) and constant current output (CC).
Under CV mode, the output voltage will be directly controlled by two knobs of coarse and fine adjustment. Under CC mode, the output current will be controlled by two knobs of coarse and fine adjustment. For example, the voltage is set as 16V, the current is set as the maximum rated value and the access load is 8./300W. 16V/8. = 2A < maximum rated value, so the constant voltage outputs 16v and 2A power supply.
Operation steps:
- Connect the output lead: connect the instrument output terminal to the load in the mode as follows.
- Open power supply: press the power key and the starting instrument will enter the working status.
- Voltage setting: adjust two knobs of fine and coarse voltage adjustment and set the voltage as 16V.
- Current setting: adjust two knobs of fine and coarse voltage adjustment to set the constant current value as the maximum rated value.
- Open output: press .ON/OFF. Key (backlight will turn green) and the instrument will work under the constant voltage output mode.
Hint: under CA mode, if the load changes cause the output current exceed the setting value, the instrument will be switched to CC mode according to the setting current, and the output voltage will be reduced proportionally. At this time, the current setting value will be increased and CV output will be recovered.
Constant current output
For example, the voltage is set as 16V. the current is set as the maximum
rated value 5A (eTM-305). The access load is 1./300W. because 1..5A = 5V < 16V
and 16V/1. = 16A > 5A, the channel constant current will output 5V and 5A
power.
-
Connect output lead: connect the instrument output terminal to load in the mode shown in the following figure.
Incorrect connection may cause damage to the product or equipment connected to this product. -
Open power supply: press the power key and the starting instrument will enter the working status.
-
Voltage setting: adjust two knobs of fine and coarse voltage adjustment and set the voltage as 16V.
-
Current setting: adjust two knobs of fine and coarse voltage adjustment to set the constant current value as the maximum rated value.
-
Open output: press .ON/OFF. Key (backlight will be green) and the instrument will work under the constant current output mode.
Hint: under CC mode, if the load changes cause the output voltage cause the setting value, the instrument will be switched to CV mode according to current voltage, and the output current will be reduced proportionally. At this time, the voltage setting value may be increased and CC output will be recovered.
Maintenance
Regular check
- In the product use process, in order to ensure the product to achieve the best working conditions, please do check regularly.
- Check the power supply power input socket is burned. Check the power supply output terminal is loose.
Replacement of fuse
