introduction

The innovative PeakTech 6181 power supply with color TFT display combines the advantages of a linear-controlled laboratory power supply with the remote control options that were previously mostly reserved for switching power supplies. Operation is via the graphical menu navigation and enables uncomplicated control and programming of the many functions. In addition, the device can be completely remote controlled via the enclosed PC software. To double the output voltage or output current values, the two independent channels can be connected in series or parallel. A plus/minus connection of the outputs is also possible.

General inspection

When you receive your new power supply, it is recommended to check the following steps:

check for transport damage
If the packing carton or foam protection is found to have damage, do not discard it until the complete unit and its accessories have been electrically and mechanically tested.
check the accessories
The supplied accessories are described in “Appendix A:” of this manual. Please Make sure all listed accessories are present and undamaged, if problems are found please contact your dealer or PeakTech directly.

check the device

If there is physical damage, operational error or a performance problem, please contact your dealer or directly to PeakTech. Please keep the original packaging. Ideally Should the device always be sent in the original packaging to avoid transprot damage.

Switch-on control
Connect the device to the power supply using the supplied power cable.
Attention:
To avoid electric shock, the device should only be connected to a grounded outlet.
Press the power button on the front panel. The keys light up and the screen displays the Loading screen until the device switches to the user interface. This may take a few seconds.

Output control

Checking the output power ensures that the device can reach its rated power and rated output. For the following steps, we recommend that you first read the chapter on switching the channel output on / off and setting the output values.

Voltage output test
The following steps check basic voltage functions without load:

If the instrument is not loaded, select a channel and make sure that the current setting for that channel is not set to zero.
Turn on the channel output and make sure the channel is in constant voltage (CV) mode.
Set various voltage values on this channel; Check if the actual voltage value is displayed and also the actual current value is displayed as near zero.
Check that the output voltage can be set from zero to the maximum rated voltage.

Current output test

The following steps check basic power functions with a short circuit across the power supply Issue:

Connect an insulated test lead to the (+) and (-) output terminals to create a short circuit. Use a wire diameter sufficient to handle the maximum current.
Set the output voltage to the maximum value for this channel.
Turn on the channel output. Make sure that the channel you are using is in Constant Current (CC) output mode.
Set some different current values on this channel and check if the current value is is displayed close to the set current value and check if the actual voltage value is displayed as close to zero due to the short circuit.
Check that the output current can be set from zero to the maximum rated power.
Turn off the channel output and remove the short circuit from the output terminals.

Output mode

The output mode can simplify the parameter input of CH1 and CH2. The output mode setting applies to CH1 and CH2 only, without affecting CH3.

There are four output modes:

Independent Output (Independent Mode)
The values for each channel can be set independently.
Parallel Track (Parallel Mode)
When CH1 and CH2 are connected in parallel, you can select this mode to simplify parameter input. You only need to set the parameters of the combined channel. The nominal voltage is the same as for the single channel; the current value is the sum of the current values of CH1 and CH2. Press the orange ON/OFF to turn the combined channel on / off.

Series Track (Serial Mode)
If CH1 and CH2 are serially connected, you can select this mode to simplify parameter input. You only need to set the parameters of the combined channel. The rated current is the same as for the single channel; the current voltage value is the sum of the output voltages of CH1 and CH2.

Press the orange ON/OFF to turn the combined channel on / off.

The connection method of the serial circuit of CH1 and CH2 is as shown in the Figure described below:

Channel Track (Dependent Mode)
In independent output mode, set the output parameters of CH1 and CH2 and switch to Channel Track mode. When the parameters of one channel are changed, the other channel changes proportionally. For example, in independent output mode, set CH1 voltage to 2V, current to 1A; set CH2 voltage to 4V, current to 2A. When CH1 voltage is set to 6V, CH2 voltage will be set to 12V proportionally after entering “Channel Track” channel tracking mode. If CH1 current is set to 2A, CH2 current will be set proportionally to 4A.

Note: If the setting value is outside the nominal range, it is set to the maximum.

To set the output mode:

Press the Utility key. The “Output Mode” menu is activated.
Use the ▲ / ▼ keys to select the desired mode and then use the key to select the mode.

- Check whether the voltage has been set to 0V. If so, change the voltage value.
- Check whether the current has been set to 0A. If so, change the current value.
- If the timer mode has been selected, check whether one of the sequence steps is set to 0A or 0V. Change this value if necessary.
- If the problem still exists, contact PeakTech Service.
The USB storage device is not recognized correctly:
- Check the storage medium for function with another device, e.g. a PC.
- External USB hard drives are not supported, only flash memory can be used.
