New features (version H0_P0110 dated July 2019)
Temperature compensation
Calibration commands are available for temperature drift compensation to improve current measurements even more.
Speed control
The control speed of the Voltage regulation can be adjusted via the web interface. This is useful when working with e.g. large capacitive loads.
Valuable improvement
Current overshoot
When turning on the output, the unit starts in CC-mode, reducing current overshoots. This is required for e.g. battery and laser applications.
Bug Fixes
INT MOD ANA calibration
Calibration of the analogue inputs and outputs could get mixed up after saving. In that case, recalibration is required after installing this new package.
Updating speed
Updates are processed faster due to a bug fix.
Previous updates:
Firmware version auto synchronization
Installed interface modules are checked for their firmware version during start-up. If they do not meet the requirements of the unit, the interface modules can be auto-synchronized with it.
Functions
Simulation of Internal resistance (Ri) and Leadless sensing is available now. No extra hardware required.
Ethernet logging
A logging mechanism is available for Ethernet communication. Received commands, queries or both can be logged to a file. The file is available via an Ethernet command, as well as via the web interface.
Wh and Ah instrument
Ethernet commands are implemented to measure Ampere Hour (Ah), Watt Hour (Wh), minimum/maximum output current or power.
Time and date
Ethernet commands are implemented to set and read time and date.
Temperature
An Ethernet command is implemented to read the highest temperature in the power supply.
Sequencer advanced mode
In the web console, an extra button is available to monitor the internal variables and timers of the sequencer. The new feature is very helpful during sequence development or debugging.
Valuable improvement
Master/Slave parallel
Up to 60 units can be connected in parallel now.
Remote sensing
Stability of the regulation is improved.
Improved output ripple
Very fast ripple rejection, in case of AC grid fluctuations.
Bug fixes
Master / Slave AC fail recovery
Smooth restart of output voltage after an AC fail recovery.
