Using your Programmable Power Supply

5 USING YOUR PROGRAMMABLE
POWER SUPPLY

5.1 INTRODUCTION

This chapter contains functional information about using your programmable power
supply (PPS). It covers basic information, such as connecting a load to an output
channel, and more advanced information such as the following:
1) Connecting loads in parallel to an output channel.
2) Connecting output channels in series to a load to increase the maximum
output voltage or connecting them in parallel to a load to increase the output
current.
This chapter also contains information about main operating features and
describes how to use those features. You can use your programmable power
supply in one of the following ways:
1) In a system environment, via a system controller (PC + IEEE interface). This
is called "remote operation".
2) As a bench-top instrument, using 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, voltage, and current. An output channel can operate as a
constant voltage (CV) source, as a constant current (CC) source, or as a constant
current (CC) sink (PM283x only) depending on voltage/current settings and load
conditions. The maximum output voltage or current is limited by the following:
1) The maximum voltage and current cannot exceed the output channel-specific
limits.
2) The product of voltage and current cannot exceed the output channel-specific
power limit according to the formula Vset x Iset
For output limits, refer to section 5.5.1 "Output channel ratings 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.
