PeakTech 5995 Digital AC DC Power supply Instruction Manual

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 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.

Caution! Do not switch-on the unit if the case is dented.
Prior to connection of the equipment to the main outlet, check that the available mains voltage corresponds to the voltage setting of the equipment.
Do not exceed the maximum permissible input ratings (danger of serious injury and/or destruction of the equipment).
Replace a defective fuse only with a fuse of the original rating. Never shortcircuit fuse or fuse holding.
Check test leads and probes for faulty insulation or bare wires before connection to the equipment.
Use caution when working with voltages above 35V DC or 25V AC. These Voltages pose shock hazard.
To avoid electric shock, do not operate this product in wet or damp conditions. Conduct measuring works only in dry clothing and rubbershoes, i. e. on isolating mats.
Comply with the warning labels and other info on the equipment.
Do not subject the equipment to direct sunlight or extreme temperatures, humidity or dampness.
Do not cover the ventilation slots of the cabinet to ensure that the air is able to circulate freely inside.
Do not insert metal objects into the equipment by way of the ventilation slots.
Do not place water-filled containers on the equipment (danger of shortcircuit in case of knock over the container)
Do not subject the equipment to shocks or strong vibrations.
Do not operate the equipment near strong magnetic fields (motors, transformers etc.).
Keep hot soldering irons or guns away from the equipment.
Allow the equipment to stabilize at room temperature before taking up measurement (important for exact measurements).
Periodically wipe the cabinet with a damp cloth and mid detergent. Do not use abrasives or solvents.
Do not store the meter in a place of explosive, inflammable substances.
The instrument must be set up so that the power plug can removed from the socket easily.
Do not modify the equipment in any way
Opening the equipment and service – and repair work must only be performed by qualified service personnel
Do not use this instrument for high-energy industrial installation measurement.
Measuring instruments don’t belong to children hands.

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

Precautions for using the power supply

Caution ! Before connecting the mains plugs of the power supply to the main outlet and switching on the equipment, be sure that the correct main voltage is available and polarity has been correctly observed. Incorrect polarity can damage the power supply and/or any connected equipment. Replace defective fuse only by an equivalent type. Before inserting the mains plug in the power outlet ensure that the line voltage corresponds with the selected line voltage of the power supplies.

Caution! Never use the instrument without fully closed housing.

Adjustment of output current (DC)

Caution! Before connecting this power supply to the load ensure that the specified maximum output current is not exceeded.

Disconnect the leads from the plus (+) and minus (-) terminals or the AC terminals of the power supply.
Adjust the desired output voltage with the voltage control.
Turn the current control counter-clockwise.
Short-circuit the plus and minus output terminals with a suitable shortcircuit bridge or cable (the bridge or cable must be adequately dimensioned for the desired output current).
Caution! Only possible in DC-voltage range. Short-circuit at AC-voltage range activates input-fuse.
Turn the current control clockwise until the desired current is indicated.
Remove the short-circuit bridge or cable from the plus and minus terminals.
The power supply is ready for operation now.

Operating method

To adjust the desired output voltage (0…30V), first should rotate clockwise the adjustment knob (12) to maximum, then turn on power switch (1).
Adjust adjustment knob (14) till output voltage reach required voltage value.
The LED for constant current (CC) expires and the LED for constant voltage (CV) lights up.

Caution:
This unit has excellent protection function. The adjustable output has currentlimit protection. As there is controlling circuit for regulating transistor’s power loss in the circuit, when short-circuit occurs, the power loss on large power transistors is not very high, it can’t cause any damage to the unit. But there is still power loss when short-circuit, in order to reduce aging and energy consumption, so this situation should be find as soon as possible and turn off power, then exclude the faults.

When operating is finished, put it in a dry place of good ventilation, and keep it clean. If it is not in use for a long period, pull off the power supply plug for storage.
For maintenance, input voltage must be cut off.
