Operation and connection modes
The output of the power supply is formed by three channels referenced to a common negative
channel. The power supply can be used in two different connection modes:
-
Independent channel: each channel (U,V,W) is controlled independently. The setpoint
and also the operation mode can be different for each channel.
-
Parallel channels: the three channels are controlled by the control software as a
unique channel to multiply the output current by 3. The setpoint and the operation
mode are the same for all three channels. It is mandatory to shortcircuit by hardware
the three output channels. All operation modes are available in this connection mode.
However, three operation modes are allowed:
-
Constant Voltage (CV): the output voltage is controlled to the setpoint value.
-
Constant Current (CC): the output current is controlled to the setpoint value.
-
Constant Power (CP): the output power is controlled to the setpoint value.

Limits
The DCPS output limits are defined by:
-
Maximum voltage: 750V
-
Maximum current: defined in the datasheet as
Rated Current DC (per channel)
or
Rated Current DC (total)
-
Maximum power: defined in the datasheet as
Rated Power (kW)
For example, below the limits of a DCPS160 power supply (with 750 V as maximum voltage)
are shown:
