The PMLA electronic multi-channel load has up to 3 cooling units, each with 4 mounting positions for load modules. 150 W, 300 W, 450 W or 600 W load modules are available.
Depending on power, a module occupies one (150 W), two (300 W), three (450 W) or four slots (600 W)
The modules are available in four different voltages 40 V, 60 V, 120 V and 240 V and currents from 1 A up to 120 A.
Various loads can be configured, e.g.:
1 x 600 W + 1 x 450 W + 2 x 300 W + 5 x 150 W
The total power is max. 1,800 W.
The loads can therefore be easily configured to test units with multiple outputs.
The load inputs are galvanically separated. Very simple systems can therefore be specially configured for requirements with multi-channel Burn-In equipment.
Operating Modes and Functions
The following operating modes are possible:
• Current mode
• Voltage mode
• Resistance mode
• Power mode
• Dynamic mode with up to 100 setting values
An adjustable current or voltage protection as well as voltage and current measurement functions are available.
Measurement Data Storage
A data acquisition function records up to 100 measurement points (time, voltage, current) at each channel and saves it internally.
The master device has a graphical user interface. All channels, also those of connected slave devices, can be operated.
Optional I/O Port for the following functions.
• Load setting C and V
• Load on/off
• Voltage monitor output
• Current monitor output
• Sense inputs
Factory Calibration Certificate
A Factory Calibration Certificate (FCC) can be supplied with the devices. The FCC meets the requirements according to DIN EN ISO 9000ff. This calibration certificate documents the traceability to national standards to illustrate the physical device in accordance with the International System of Units (SI). The recommended calibration interval is 2 years.
Software Tools und Drivers
LabVIEW drivers are available.
Suitable software tools are in preparation.
• Calibration of driver outputs
• Consumer test of electrical systems
• Batteries and accumulators
• DC/DC converters
• Electronic assemblies
• Electronic fuses and cut-off
• Fuse boxes
• Power distributors
By a trigger system all channels can synchronously be switched on or a programmed waveform can be started.
Cooler and Load Modules
At each device three cooling units can be installed. At each cooling unit one, two or four modules can be installed, depending on type.
The load terminals are provided at pluggable terminal strips.
The air transport from the front panel to the rear panel enables the assembly of compact rack systems without gaps. The temperature-controlled fan control provides a pleasant operating noise.
