Fig 1-5 Constant Power Mode - Prodigit 33501 Series Operation Manual

CP Mode:
At Constant Power mode, the 33501 Series Electronic Load will attempt to sink load power
(load voltage x load current) in accordance with the programmed power. (See Fig 1-5).
Dynamic wave form definition:
There are six parameters to generate dynamic wave form or pulse wave form, the 33501
Series Electronic Load will sink current from power source proportional to the dynamic wave
form, the dynamic wave form definition is shown in Fig 1-6. The period of dynamic wave form
is Thigh + Tlow, dynamic frequency = 1 / (Thigh + Tlow), the Duty cycle = Thigh / (Thigh +
Tlow)

The load current level and load status are can be set with Front panel on each module, GPIB
command. It is called manual operation and GPIB operation respectively, the load input
voltage and load current can be read back to computer through GPIB.
The GPIB operation is described in Chapter 4 GPIB operation.
