Safety Precautions

This product complies with the requirements of the following directives of the European Union for CE conformity: 2014/30/EU (electromagnetic compatibility), 2014/35/EU (low voltage), 2011/65/EU (RoHS).
To ensure the safe operation of the equipment and eliminate the danger of serious injury due to short circuits (arcing), the following safety precautions must be observed.

Damages resulting from failure to observe these safety precautions are exempt from any legal claims whatever.

General:

Read these operating instructions carefully and make them available to subsequent users.
Always observe the warning notices on the device; do not cover or remove them.

Pay attention to the use of the device and only use it in its appropriate overvoltage category.
Familiarize yourself with the functions of the device and its accessories before using it for the first time.

Do not operate the device unattended or only when it is secured against unauthorized access.
Only use the device for its intended purpose and pay particular attention to the warnings on the device and information on the maximum input values.

Check that the device is functioning correctly before use, especially if the connected load has sensitive electronics.
Always observe the applicable health and safety regulations and operating instructions!

Electrical safety:

These devices are suitable for a mains voltage of 107 to 253V AC.

The appliance must be positioned so that the main plug can be easily removed from the socket.
Ventilation slots in the housing must be kept clear (risk of heat build-up inside the appliances if covered)

Do not insert any conductors or other objects through the ventilation slots
Do not place any liquids on the appliances (risk of short circuit if the container tips over).

These laboratory power supply units are devices of protection class I with an earthed housing. Only use sockets with protective earth for connection and ensure that the connection cable is undamaged.
Do not operate the appliance unattended or protect the device against unauthorized access
Voltages above 25 VAC or 60 VDC are generally considered dangerous voltages.
Work on dangerous voltages may only be carried out by or under the supervision of qualified personnel.
Wear suitable protective equipment when working with dangerous voltages and observe the relevant safety rules.
Do not exceed the maximum permissible input voltages under any circumstances (risk of serious injury and/or destruction of the device)
Never touch the bare terminals when working with dangerous voltages during operation.
Do not use several of these switching power supplies in parallel or series operation. Improper use can cause damage that is excluded from any warranty.

Measuring environment:

These devices are only suitable for use in dry indoor areas and have no protection against dripping or splashing water.
These devices are only suitable for use in dust-free indoor areas and use a fan for active ventilation and ventilation slots for cooling the interior. A dusty environment can cause dust to be sucked in and thus damage the device due to short circuits or insufficient cooling.
Avoid any proximity to explosive and flammable substances, gases, and dust. An electrical spark could lead to an explosion or deflagration – danger to life!
Do not carry out measurements in corrosive environments, the device could be damaged or contact points inside and outside the device could corrode.
Avoid working in environments with high interference frequencies, high-energy circuits, or strong magnetic fields, as these can have a negative effect on the device.
Avoid storage and use in extremely cold, damp, or hot environments, as well as prolonged exposure to direct sunlight.
Avoid storage and operation in places with high, condensing humidity to prevent dripping water in the appliance.
Before starting the measurement operation, the device should be stabilized to the ambient temperature (important when moving from cold to warm rooms and vice versa)

Maintenance and care:

Never operate the appliance if it is not completely closed.
Check the appliance and its accessories for damage to the insulation, cracks, kinks, and breakages before each use. If in doubt, do not use the appliance.

Switch off the appliance before changing the fuse.
Only replace defective fuses with a fuse corresponding to the original value. Never short-circuit the fuse or fuse holder.
Maintenance and repair work on the appliance may only be carried out by qualified personnel.

Clean the housing regularly with a damp cloth and a mild cleaning agent. Do not use corrosive abrasive cleaners.
Do not make any technical changes to the appliance.

Attention!
Laboratory power supplies are not designed to charge batteries. Incorrect use can lead to serious damage to the device or the battery, which is excluded from claims of any kind.

Cleaning the cabinet
Before cleaning the cabinet, withdraw the main plug from the power outlet. Clean only with a damp, soft cloth and a commercially available mild household cleanser. Ensure that no water gets inside the equipment to prevent possible shorts and damage to the equipment.

Operating method

Setting the constant voltage output:
Set the desired output voltage with the voltage knob (3). Press on the voltage knob, to select the desired digital point for coarse or fine adjustment. Once the desired voltage is set, turn on the output with the Output button (8). The C.V. and Output-LED indicate the voltage output.

Current limitation/constant current output:
Set the desired current limitation when output is off with the current knob (4). Press the current knob to select the desired digital point for coarse or fine adjustment. Once the desired current is set, turn on the output with the Output button (8). The C.C. and output LEDs indicate an active current limitation.
Note:
The maximum output current is determined by the connected load. You can’t charge a connected consumer with a higher power than it needs.
PeakTech 6226: In current setting values under 9.9 A, the display will show X.XXX (1 mA resolution); when the setting value reaches or over 9.9 A, the display will show XX.XX (10mA resolution).
Activate/deactivate key lock:
Once you have adjusted the desired settings, press and hold the voltage and current controls for 3 seconds to activate a key lock. Now only the output button is operable, but the voltage and current control can’t be changed. Press both buttons again for 3 seconds to disable the key lock

Note

If the power supply cannot be turned on and the mains supply is turned on, the fuse of the laboratory power supply may be triggered. Turn on the laboratory power supply, unplug the power cord, and replace the fuse.
Does the replacement of the fuse is not successful, maybe a defective in the device can be present. Consult your dealer to carry out an inspection.
If the output voltage in constant voltage mode is lower than the preset voltage and the CC indicator lights, the power supply has automatically switched to the constant current mode. Check the connected load or increase the output current.
If the output current in the constant current mode is lower than the preset current and the CV indicator lights, the power supply has automatically switched to the constant voltage mode. Check the connected load or increase the output voltage.

If the output voltage in constant voltage operation is not stable or jumps, it is probably because the mains supply voltage drops below 90% of the rated value. If the problem is not caused by the mains supply voltage, contact your dealer.

Safety Caution

The mains power must be switched off before servicing and servicing should be referred to a qualified person. The unit should be stored in a dry and well-ventilated place and the power cord removed if stored for long periods.
Laboratory Power Supplies are not designed for charging batteries. Any use of this type can cause serious damage to the device, which is exempt from any legal claims whatever.

Do not operate the device to power inductive loads, such as electric motors, which act as generators during overrun and thus can produce a reverse voltage.
Replace the fuse only with an identical fuse.
