MCU2
The MCU2 (Master Communication Unit2) serves as a data interface to a maximum of 60 MLM 24 VAV field Diffusers, as well as a gateway to BMS protocols such as BACnet/IP, BACnet MS/TP and LonWorks.
PSU2
The PSU2 is designed to meet the power requirements of the Rickard MLM24 diffuser network.
It contains a universal input switching power supply making use of the latest technology for energy efficiency, safety and low EMI. The product is optimized to meet the inductive requirements of multiple actuator motor drives.
iPSU
The iPSU serves as both a data interface and power supply unit to a maximum of 15 MLM24 VAV field diffusers. It also contains a gateway to BMS protocols such as BACnet/IP and BACnet MS/TP. It serves as cost effective alternative to a PSU and MCU combination when the installation is smaller.
