In terms of performance, a linear regulated supply has a very precise regulating
properties and responds quickly to variations of the line and load. Hence, its line
and load regulation and transient recovery time are superior to supplies using
other regulation techniques. The power supply also exhibits low ripple and noise,
is tolerant of ambient temperature changes, and with its circuit simplicity, has a
high reliability
The power supply contain a linear regulated power supply. It is controlled by a
control circuit that provides voltages to program the outputs. The power supply
sends back to the control circuits a voltage representing the output at the
terminals. The control circuits receive information from the front panel and send
information to the display. Similarly the control circuits ‘’talk’’ to the remote
interface for input and output with the GPIB and RS-232 interfaces. The remote
interface is at earth ground and isolated from the control circuit and the power
supply.
