1. INTRODUCTION
GP-305 , 3010 , 503 , 505 series are regulated DC POWER SULLPY units with voltmeter
and amperemeter : GP-305 can supply the DC power of 0 to 30V/5A
GP-503 can supply 0 to 50V/3A.
GP-505 can supply 0 to 50V/5A.
They are provided with continuously variable coarse adjustment and the output voltages,
and with continuously variable current adjustment in a range of 10 to 100%.
Current limiting and overload protection functions are built in to protect the load under
any circumstances.
The supply features anloge voltmeter and amperemeter, enabling the user to monitor
the supply's operation at a glance.
LEDs for Constant current ( C.C ) and Constant Voltage ( C.V ) enables monitoring of
operation status.
Main input voltage AC230V and 50/60Hz are supported.
2. FEATURE
Built in output current limiter circuit
Availability of series and / or parallel operation

3. PRECAUTIONS
3-1. Line voltage selection
This instrument must be operated with the correct line voltage selector switch setting
and the correct line fuse for the line voltage selected to prevent damage.
The instrument operates from either a 90V to 132V or 198V to 250V line source.
Before line voltage is applied to the instrument , make sure the line voltage selector
switch is set correctly.
In the case of the line voltage selector switch selected , must be operated to the
correct line fuse.
This instrument is the of category
To change the line voltage selection
1. Make sure the instrument is disconnected from the power source.
2. Pull out the line voltage selector switch on the bottom panel.
Select the arrow mark position of the switch from Table 3-1.
Select the arrow mark to the desired position and plug it in.
3. Pull out the line fuse holder containing the fuse for overload protection.
Replace the fuse in the holder with the correct fuse from table3-1 & plug it in.

3-3. Cleaning
1. To clean stained casing, lightly rub the stained area with a soft cloth dipped in a
neutral detergent.
2. If the surface of the panel is dirty, use the same method to clean.
If the panel is heavily stained, rub the affected area lighty with a soft cloth soaked
in light neutral detergent or alcohol.
3. Never use highly volatile material such as benzene or paint thinner.
