GENERAL INFORMATION
1.0
DESCRIPTION :
1.1
The 1305 DC Power Supply is a compact, high
perfomance Dual output DC power supply for industrial
and laboratory use.
1.2
The two main outputs are continuously variable from 0 to
32V and can supply 5A max each. They can be operated
in constant voltage or constant current modes. Automatic
transition from CV to CC mode may be set at any voltage
or current within the range. Separate front panel meters
are provided to monitor output voltage and load current of
the variable output sections.
1.3
The output voltage and current limit settings of the
variable outputs can be varied manually using front panel
controls.
1.4
All outputs are floating i.e., neither the output positive
terminal nor the negative terminal (nor any point within
the regulator circuitry) is connected to ground.
1.5
The power supply is designed to operate in ambient
temperature of upto 40°C and full output may be drawn
continuously provided proper ventilation is provided around
the power supply. The power supply works from mains
supply of 115V or 230V AC, 47-63 Hz ( With Internal Tap
Selector).
