Details

Configuration
The PMLI electronic multi-channel load has up to 12 slots 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).

Load Modules
The modules are available in three different voltages 60 V, 120 V and 240 V and for currents of 4.5 A to 80 A.

Various loads can be configured, e.g.:
1 x 600 W + 1 x 450 W + 2 x 300 W + 1 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 to 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 2 presets

An adjustable trigger voltage enables current only to flow when the defined voltage is exceeded.

Load Modules
Load modules are available in three voltage categories and four power classes.

Load Connections
The load inputs are connected to jack-in terminal strips. All load inputs are galvanically separated.

Analog Measurement Outputs, Analog Control Input
For each load module, analog measurement outputs 0 ... 10 V for voltage and load current are available.

Via an analog control input the load current can be additionally set by 0 ... 10 V.

Cooling
The air supply from the front panel to the rear panel enables the assembly of compact rack systems with no gaps. The temperature-controlled fan control provides a pleasant operating noise.

Devices and Interfaces
are available in the following versions:

PMLI-M Master device with GPIB + RS-232 interface and PMLI system bus for connection of up to 8 slave devices.
PMLI-S Slave device with PMLI system bus for operation on a master device and with an output for a further slave device.
SLOT4 Empty cooler module (without load modules) with 4 free slots. (1x, 2x or 3x required per device depending on channels).
PMLI05 Optional external LAN-RS-232 adapter

Programming
Programming takes place in SCPI syntax. All channels can be addressed individually or in groups. 
Current LabVIEW® drivers and tools can be downloaded from our website.

Documentation
We supply a User Manual as pdf file and printed General Safety Instructions, each in German and English.
