MEAN WELL intelligent products are those equipped with communication interfaces, parameters and functionality can be adjusted or changed via the interfaces.

Take the RPB-1600, the intelligent battery charger as an example, users can easily adjust charge curves to deal with various types of batteries owing to its PMBus communication protocol. Mean Well divides the intelligent products into four sections: PMBus, CAN bus, DALI, DALI-2 and KNX. Please read the following for more information.

>> PMBus
PMBus stands for Power Management Bus, which is an open standard power-management protocol, featuring flexibility and highly versatile standard.

Those intelligent products with the protocol are able to do parameter settings, such as output voltage/current, status reports, etc. The models are as below:

RCP-2000
RCP/RPB/RCB-1600
RSP-1600PM
DRP/DBR/DBU-3200
DPU-3200PM
PHP-3500
UHP-1500/2500
HEP-1000
HEP-2300PM
SHP-10KPM
CMU2C-P

>>CAN bus
The Controller Area Network bus is a serial communication bus designed for robust and flexible performance. Those intelligent products with the protocol are able to do parameter settings, such as output voltage/current, status reports, etc.

The models are as below:
RSP/RCP/RPB/RCB-1600CN
DPU/DRP/DBU/DBR-3200CN
PHP-3500CN
UHP-1500CN/2500CN
HEP-1000CN
HEP-2300
SHP-10K
DRS-240CAN/480CAN
CMU2C-C

>>Modbus
Modbus is a data communication protocol originally intended for Programmable Logic Controllers (PLCs). With numerous variants, MEAN WELL chose Modbus RTU (Remote Terminal Unit) with EIA-485 due to its robust and flexible performance advantages.

Intelligent products equipped with this protocol can configure parameters such as output voltage/current and generate status reports. The following are the models that incorporate this technology:
HEP-2300MOD
SHP-10KMOD
DRS-240/480

>>DALI
DALI stands for Digital Addressable Lighting Interface, an internationally recognized digital protocol for controlling lighting devices such as LED drivers. Products or drivers equipped with this protocol can integrate with DALI controllers to create intelligent lighting solutions for indoor applications. The following are the models that incorporate this technology:
LCM-25DA/40DA/60DA
LCM-40UDA/60UDA
ELG-75CDA/100CDA/150CDA/200CDA/240CDA
ELG-75DA/100DA/150DA/200DA/240DA
HLG-320-CDA
HBG-100DA/160DA/200DA/240DA
HBC-100PDA/160PDA
HVGC-480ADA/650DA
ODLC-45DA/65DA
LDC-35DA/55DA/80DA
PWM-60DA/90DA/120DA
IDLC-45DA/65DA
IDPC-45DA/65DA
DAP-04
LDD-H-DA

>>DALI-2
DALI-2 represents an updated version of DALI. The primary distinction of DALI-2 lies in its more precise specification of electrical tolerances and the addition of new commands, such as extended fade-time, which allows for fades ranging from 0.1 seconds to 16 minutes.

DALI-2 products or drivers are compatible not only with DALI-2 application controllers and input devices but can also be seamlessly integrated into existing DALI systems. The following are the models that incorporate this advanced technology:
LCM-25DA2/40DA2/60DA2
PWM-60DA2/90DA2/120DA2/200DA2
ELGC-300-L/M/H-ADA
HBGC-300-L/M/H-ADA
HVGC-1000-L/M/H-DA
LDC-55DA2
LCM-40TW
DLC-02

>>KNX
KNX is an open standard for both commercial and residential building automation, encompassing all facets of home and building control, including lighting, heating, cooling, ventilation, and blinds/shutters.

Products or drivers equipped with this protocol can integrate with KNX controllers and switches to create small home networks or be installed in smart commercial buildings. The following are the models that incorporate this technology:
LCM-25KN/40KN/60KN
PWM-60KN/120KN
KAA-8R(-10)
KAA-4R4V(-10)
KDA-64
KNX-40E-1280D
DLC-02KN

For Building automation, MEAN WELL utilizes KNX as the solution. Please refer to the KNX building automation website for detailed information and relevant applications.https://meanwellkulon.net/products-knx/

For wireless lighting control, MEAN WELL employs Bluetooth low energy Mesh technology. Currently, our product line includes the LCM-IOT and PWM-IOT series, which are suitable for applications requiring constant current and constant voltage control. For detailed information, please refer to the specifications.

It is 125 nodes that can be controlled at a time by CASAMBI app.

For industrial automation, MEAN WELL suggests using PMBus and CAN bus for digital control and monitoring.

The brightness increasing in a steady/linear rate isn't observed as a linear increase to the human eyes. It is light source whose dimming curve is in logarithmic mode shows a linear increase to the human eye. There are linear and logarithmic dimming curves selectable for users in DALI.

MEAN WELL's CAN bus products meet ISO 11898 and the bus rate is 250kbps. Max. communication distance is at least 150m for the products.

DALI-2 is an upgraded version of DALI-1. DALI-2 has been adjusted and optimized for the following contents.

1. The more precise specification of electrical tolerances and the restructuring of the specification reduce the risk of malfunctions and enhance data accuracy in DALI-2.
2. DALI-2 has introduced 14 new commands/features while eliminating 1 command. Among these additions, the most significant one is the extended fade time, which ranges from 0.1 seconds to 16 minutes.
3. DALI-2 optimizes the communication sequence among the application controller, input device, and control gear, enabling devices from diverse manufacturers to operate harmoniously on the same DALI bus.
4. Before being allowed to use the DALI-2 trademark, DALI-2 products must undergo full certification by the DiiA Association.
DALI-1 and DALI-2 products can be used together. Compatibility issue is shown in the table below.

Please refer to the table.

For models equipped with PMBus, like RCP-1600, you can refer to the chapter on communication interface in the user manual. For those recognized as optional (non-standard) features, such as RCP-1600-48CAN, please apply for them through your local distributor.
