Inverters (S4 and S5)

PDI’s inverters are the industry standard for telecom and critical environment power protection. At the heart of PDI’s Model S4 Inverter are scalable 3.5 kVA inverter power modules which can be stacked in an N+1 redundant configuration up to 21 kVA. This modular scalability makes the S4 ideal for overlay applications where future power growth is anticipated. All modules are packaged into a receiver cabinet allowing rapid and safe exchange of any component without interruption to the critical load.

The PDI S5 Inverter uses high density circuitry to provide 1500 Watts of power in a slim 1U rack mountable enclosure. DC noise filtering circuits on the S5 practically eliminate ripple current (<30 dBNRC and less than 2mV psophometric), a byproduct of most inverters that can potentially damage even large DC battery banks. The S5 can be paralleled for capacity or redundancy using “plug and play” synchronization cables.

Branch Circuit Monitoring Systems (BCMS)

PDI’s Branch Circuit Monitoring System (BCMS) can measure and remotely monitor the current and voltage on each individual panel board circuit, allowing for proactive management of every device in your facility. PDI’s BCMS is available as factory OEM installed or as a retrofit kit. There are different monitoring packages available from PDI for your BCMS. PDI’s BCMS is a patented technology.

WaveStar BCMS Hub

PDI’s WaveStar™ BCMS Hub can collect information from up to 35 downstream BCMS-enabled power quality products (up to 70 panel boards) in a data center. It can operate as a standalone system, connect to your building management system or deliver power data to the cloud utilizing the PDI PowerMap service. Features include a touch screen monitor, easy to use interface, and exportable Microsoft Excel reporting. The WaveStar BCMS Hub makes real-time power monitoring and management more efficient and easier to interpret.
