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.

The iPSU network side consists of industry standard hardware and software interfaces. It also serves as a connection point to the proprietary MLM24 Application software. The iPSU also makes it possible to configure master and slave relationships between any of the 15 diffusers connected to it.
 
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.
 
DATA COMMUNICATIONS:
 
The iPSU features a field bus front-end to feed power and data communications to a daisy chained diffuser installation. 
The network back-end consists of industry standard hardware and software interfaces. It also serves as a connection point to the proprietary MLM24 Application software.
