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.
