AVSL 650.682 NETVOEDING POWER SUPPLY - Manual (Page 4)

UK
The SkyTronic range of adjustable power supplies is fitted with high precision voltage and
current controls. The voltage is continuously adjustable and the max. output current limit can
also be adjusted. The power supply can be used as a constant power source. In that case the
current is continuously adjustable.
The power supply has been designed for professional use in work shops, laboratories and
schools.
The digital voltage and current display has a precision of 1 decimal with a max. deviation of ±
1% + 2 digits. The high precision control circuit can reach via an external measurement
instrument an accuracy of 5mV for voltage and 10mA for current.
Operation
Front panel:
1. Voltage and current display
2. Current adjustment
3. Fine adjustment of current
4. Fine adjustment of voltage
5. Voltage adjustment.
6. LED indicator of voltage source (current limit is not activated)
7. LED indicator for current source (current limit is activated)
8. ON/OFF switch
9. 3 connection terminals:
red (+)
black (-)
green (earth ground)
Load connection
Adjust the required voltage and connect the unit to be powered to the red (+) and black (-)
terminals. The current display shows the supplied current. If the current LED lights up, the
power supply is overloaded or shorted. Check the connections and adjust the load in order to
ensure trouble-free operation.
If you want to use the unit as a constant power supply, rotate both voltage controls completely
clockwise (max. voltage) and the current control knob completely anti-clockwise until the
required current value is reached.
Under normal conditions, the current control knob can be turned completely clockwise (for
max. current) or rotated back to a required maximum current value in order to protect the
connected unit.
Safety recommendations:
- Check the case and the leads for damage.
- For indoor use only
- Do not use the unit in humid areas
- Do not spill liquids inside the housing.
- Do not place the unit at a warm place (max. 30°C)
- Do not obstruct the ventilation holes and heat sink. Leave enough space around the unit to
ensure sufficient ventilation.
- The heat sink might get hot during operation. Do not touch during operation !
- Do not open the housing – leave all repairs to a qualified technician.
