LVD Manager vers. 1.5.0.0

(2019/03/10)



Different Hardware Versions

During the time some hardware improvements was introduced and the following

hardware versions exist (exept PL model):

0(or 1). in period from May to Aug 2017 - first release


2. since Sept 2017 - minor pcb improvements.


3. since Nov 2017 there are a few major improvements:

a) 'Soft start' feature introduced. This is 'must have' feature for

large capacitive loads such as inverters. Also it protects from short circuit

or overload. This is true only on 'turn on' time not while it is already in 'on' state.

b) Temperature is always measured and available to watch.

This is different in early versions where temp. readings was available

only when voltage on input is more than 5V.

4. since Sept 2018 - minor pcb improvements for AL models.


The newest PL model has different MCU and therefore hardware versions are different:

1. since May 2019 - initial version.


New and Updated Features


since 1.5.0.0 (current version)

Added support for newest PL devices.

Minor improvements and bug fixes.

New firmware (v.0.30) added for all usb enabled models.


since 1.4.0.0

Minor improvements and bug fixes.


since 1.3.0.5

Fixed poor USB connection related issues.


since 1.3.0.2

New firmware (v.0.27) added for all usb enabled models.

IO port configuration tools added.

Sense source selector was added for overvoltage cut-off. Now it is possible

to use it as overcharge protection for batteries in

charger->(+in OVD +out)->battery topology.

since 1.3.0.0

New firmware (v.0.25) added for all usb enabled models.

Temperature control added for all devices with new firmware.

Please note that temperature sensor is located near power switch and

its main task is to protect device from overheat not to monitor ambient temperature.


since 1.2.0.0

New firmware (v.0.20) added for all usb enabled models.


since 1.1.0.0

Minor bug fixes. This version is available as auto update.

since 1.0.1.3

New firmware (v.0.17) added for all usb enabled models.


since 1.0.1.2

New firmware (v.0.15) added for all usb enabled models.


earlier versions

Lot of improvements and bug fixes. Please consider to upgrade form earlier versions.



Included firmwares and its change logs


All USB enebled models.

v.0.30 (currently embedded version)

Fixed IO port state on power reset.

Various small bug fixes and improvements.


v.0.29

Fuse Auto-reset time range limited to 3-60 secs. Default is 5 secs.


v.0.27

IO port configuration support added.

Overvoltage sense source selection (In/Out) added.


v.0.25

Temperature inside unit can now be monitored.

(early hardware versions (0-2) needs on input > 5V to mesure temp.)

Working range now has temperature min/max settings.

Please check these settings after update as they may have random values.

Various small bug fixes and improvements.


v.0.20

Fixed false SWITCH FAILURE state detection on sudden input voltage loss while

device was ON. Better fault detection on overheat and driver failure.


v.0.17

Auto-ON on power cycle feature added. After power reset if input voltage

will be in working range and not below lvd cut-off point then module

will turn ON automaticly. Normally you would need to reach lvd reconnect

threshold level to tourn it on.

v.0.15

Remote ON/OFF pins are swapped to confirm labeling.


earlier versions

Lot of improvements and bug fixes. Please consider to upgrade form earlier versions.
