Ethernet Interface with Integrated Sequencer Included as Standard

• Arbitrary waveform generator or standalone automation. 
• Sequencer is integrated in the ethernet controller
• User defined waveforms can be stored in the sequencer

• Ideal for repetitive testing and automation
• Can work like a PLC or stand-alone automation: steps interact with the actual inputs and outputs
• Waveform generator independant of computer allowing for standalone operation
• Steps from 1m/sec to hours

Uo to 4 plug and play interface choices with no limitations for interface combinations.

Accessable by a built in Web Interface

Comes Complete with Ethernet Control Software

Optional Power Sink

• 2-Quadrant Output: Power Sink

  The 2-quadrant operation maintains the output voltage constant regardless the output power is positive or negative. Ideal for PWM-speed controlled DC-motors and ATE-systems.

Without Power Sink - Uncontrolled voltage rise when the load current goes negative:

With Power Sink - Dynamic reaction of power sink. Load current switches between positive and negative.

Without Power Sink - Down programming with no load with a normal power supply: voltage falls very slowly.

With Power Sink - Down programming with no load with a power sink equipped power supply: results in short voltage fall times.

Standard Features:

High Voltage Isolation
A higher output isolation allows series operation up to 100 V for low voltage units and 1400 V for high voltage units.

Sequencer
Arbitrary Waveform generator or stand alone automation.

Digital Voltage and Current Setting
Reliable, long life digital encoders are implemented at the front panel. Includes total front panel lock (also for CV- / CC- knobs) and a coarse or fine pitch adjustment depending on the turning speed.

Ethernet Controller
Ethernet interface for programming and monitoring

USB Input
(under development) Front panel USB input for exchange of settings and waveforms (host)

Options:

High Speed Programming
A 10 to 20 times higher programming speed and lower output capacitance. Excellent for laser applications, test systems or as current source with low parallel capacitance as used in plasma chambers.

Two-Quadrant Output: Power Sink
Two quadrant operation maintains the output voltage constant regardless the output power is positive or negative. Ideal for PWM-speed controlled DC-motors and ATE-systems.

Software Control and Interfaces
Field installable interfaces: Isolated Analog Programming, Digital I/O, Isolated Contacts, Serial Controller with multiple protocols RS232, RS485, RS 422 and USB  (device)
