5 USING YOUR PROGRAMMABLE
POWER SUPPLY
5.1 INTRODUCTION
This chapter contains functional information about usin
your pro
rammable power
supply (PPS). It covers basic information, such as connectin
a load to an output
channel, and more advanced information such as the followin
:
1) Connectin
loads in parallel to an output channel.
2) Connectin
output channels in series to a load to increase the maximum
output volta
e or connectin
them in parallel to a load to increase the output
current.
This chapter also contains information about main operatin
features and
describes how to use those features. You can use your pro
rammable power
supply in one of the followin
ways:
1) In a system environment, via a system controller (PC + IEEE interface). This
is called "remote operation".
2) As a bench-top instrument, usin
the front panel keys, indicators and display.
This is called "local operation".
Each output channel of the power supply is a dc power source with controlled
limits for power, volta
e, and current. An output channel can operate as a
constant volta
e (CV) source, as a constant current (CC) source, or as a constant
current (CC) sink (PM283x only) dependin
on volta
e/current settin
s and load
conditions. The maximum output volta
e or current is limited by the followin
:
1) The maximum volta
e and current cannot exceed the output channel-specific
limits.
2) The product of volta
e and current cannot exceed the output channel-specific
power limit accordin
to the formula Vset x Iset
≤
Pmax.
For output limits, refer to section 5.5.1 "Output channel ratin
s and
characteristics".
CAUTION: You may turn on your power supply if you are sure that the
installation instructions as described in Chapter 3 have been
followed. The power supply is ready for use within a few seconds
after power-up. After a warm-up time of 30 minutes, your power
supply meets the specifications listed in the Reference Manual.
