Power Supply Configurations

Flexibility and configurability are important in many
power applications. With a wide range in designs and setups, let’s take a look at how power supplies can be used in different applications to take advantage of their extensive power envelopes. SIGLENT linear power supplies can operate at both max voltage and max current at the same time. This means the supply is never limited by power and is always either in constant voltage (CV) mode or constant current (CC) mode.

Linear supply channels are also often isolated from ground. This includes the SPD3303X and SPD4000X series. Linear supply channels can also often be used in series or parallel. Putting channels in series increases the voltage while adding channels in parallel increases the current. These power supplies have internal connections that enable those configurations without complicating external wiring. These power supplies also have some 4 wire sense capability as described above. This table explains the configuration of the channels and connections on linear supplies:

SIGLENT switching power supplies are configured to
allow more flexible use of the output power. These channels operating envelopes follow a curve that is related to the total power and the efficiency of the supply. For instance, the SPS5081X can provide 4.5 Amps at 80 Volts or 15 Amps at 24 Volts. Those points are connected by a curve that touches on 9 Amps at 40 Volts. Here is the curve for the 40 Volt and 80 Volt SPS5000X series models:

Most of these models have their connection points on the rear of the instrument. There are also limits to the number of channels that can be used in series or parallel. Use this table as a reference for switching power supplies:
