with the load. When used in places with high demand, make sure one of the
output terminal “+” or “-” must reliably connects with post head “GND” so as
to reduce output ripple voltage.
(4)Constant current setting: Firstly, regulate the voltage to any value between
3-10V, and regulate the knob (6) to the minimum. (0A), and then use a lead to
make positive and negative polarities shorted. Regulate the Current regulation
setting knob (6) to the necessary current value. Remove the short lead, and
then regulate the voltage to the necessary value, connect the load, then you
can start your work. At this moment the power supply is under the constant
current. That is the current remains the same, while the voltage changes with
the load. (There will be slight sounds when positive and negative polarities are
shorted. That is normal phenomenon)
IV Matters need attention
1. Input voltage: Confirm the input voltage is AC220V±10% 50Hz or
110V±10% 60Hz.if the input voltage is wrong, the power supply can not work
normally, and even it will lead to serious result.
2. Working condition: For the purpose of heat dissipation, there should be
enough space around the power supply. The two sides and back of the power
supply should have more than 10cm space. This kind of power supply uses
intelligent fan controlled by temperature to cool. When inside temperature of
