3 Product Overview
This chapter provides an overview of the APS 6RL Series programmable DC power supplies.
It introduces the reader to general operating characteristics of these power supplies.
3.1 General Description
The APS 6RL Series Regenerative Electronic load is designed to provide accurate, stable and
clean DC load conditions to a power supply under test and regenerate most of the energy
back to the grid. The APS 6RL Series regenerative load can be operated from the front panel
(manual mode, also referred to as Human Machine Interface or HMI) or using and of the
available digital or analog remote control interfaces. Standard interfaces are USB and
isolated analog I/O. Other interfaces can be added as options.
These programmable DC loads are especially suitable for test systems and industrial controls
due to their compact construction in a 19” enclosure (3U rack height). Apart from basic
functions of electronic DC loads, current or power set point curves can be generated using
the integrated function generator (sine, rectangular, triangular and other curve types). If
needed, arbitrary generator curves up to 100 points can be saved to and loaded from an
USB memory stick.
Using the optional plug-in digital interface modules, other interfaces such as Profibus,
ProfiNet, ModBus TCP, CAN or CANopen can be added easily. These enable the units to be
connected to standard industrial buses simply by changing or adding a small interface
module. The configuration for each of these, if required at all, is simple.
In addition, the units offer as standard the possibility for parallel connection using a Share
bus master/slave mode for constant current sharing plus a genuine master-slave
connection. Summing of master and slave units measurements by the master is standard.
Operating in this way allows up to 32 units to be combined to a single system with a total
power of up to 480 kW.
All models are controlled by microprocessors. This enables an exact and fast measurement
and display of setting and read back values.
The performance of the 6RL Series regenerative load models are detailed in section 4,
“Technical Specifications”. Maximum voltage, current and power capability depends on the
specific model. This manual covers standard 6RL Series models. If your unit has a custom
voltage and current range, most of the information in this manual still applies.
