ALL-PURPOSE DC REGULATED POWER SUPPLY
The CSI-4PLUS DC regulated power supply is a multi-function power supply
with four-way DC and one-way AC. The special design of the internal circuitry improves
the security, stabilization and reliability of the power supply. The power supply has an
accurate digital voltage meter and current meter which can synchronously show the
accurate output voltage and current. All of the fan-out is equipped with the standard
security faucet which can largely improve the security. As a new multi-function power
supply, it is more functional for schools and scientific research institutions to use as
teaching equipment.
MAIN FUNCTION:
DC 0-500V adjustable output: four digit figure voltage meter indicates the output
voltage. The output current is 5mA. When the voltage is over-loading, it can turn off
automatically. It must be turned on by hand.
DC 0-20V adjustable output: four digit figure voltage meter indicates the output
voltage. The output current between 0 and 6A can be adjustable. Four-digit figure current
meter indicates the output current. When the circuit shorts or is in constant current mode
of operation, the alarm will ring and can reset automatically.
It can choose the DC output between the ±5V and ±8V. The maximum output
current is 1.2A. This output features with the over temperature protection, the
dissymmetrical output and the short circuit alarm. It can reset automatically.
It can choose the AC output among the 2V, 6.3V, 9V and 12V. The maximum
current output is 2.5A. This output features with overload (e.g. short circuit) protection
and alarm. It can reset automatically.

27. Power fuse; when you replace with a new fuse, please notice the specifications,
then refer to the following method.
1. Input voltage: before switching on the power supply, please make sure
that the local electrical supply is the same as the input voltage of this
power supply.
2. Abnormal operation: Do not use your hands or other parts of the body to
touch the fan-out of the DC500V to prevent being hurt
A. The connection between the fan-out and the load must be locked-in, if
not the output terminal may hurt you.
B. The DC ±5V, ±8V and the AC fan-out can not be shorted because the
unit has short-circuit protection. If it were to occur, the unit should be
shut off. To prevent the burning of any internal circuits, do not short the
fan-out connection.
C. There is high voltage inside this unit, please do not open because it can
be very dangerous.
D. Placement: After operating, place the unit in a dry place with good
ventilation and keep it clean.
E. The replacement of the fuse: if the fuse is damaged, try to find the
reason why then replace with the exact style fuse. Turn off the AC input
supply before replacing to ensure safety.
F. Correcting a malfunction: If there is something wrong with the power
supply, contact a professional repair person to fix it. Do not open the
case yourself to avoid further malfunctions and harming yourself.
