 Smart CS-36V5: 20/30A 3 phase 36xC13
  3-Phase High Density Power Distribution Unit with local and remote power monitoring


  • Description
  • Specifications

The three phase Smart Cabinet Power Distribution Units (CDU) provide reliable power distribution combined with local and remote power monitoring and environmental monitoring via IP. Use the network interface to view power, temperature and humidity levels via Web browser, or receive SNMP–based alarms and email alerts when conditions exceed defined thresholds.

415 V 3-Phase power distribution to the rack level is fairly new technology in North American Data Centers. Increased power demand, higher power costs and reduced power availability are driving technologies like this that increase the efficiency within the Data Center. By bringing single phase 240 V power directly to the devices in the cabinet there is a sizable efficiency gain both in the power distribution system and in device itself. If you require further information you can reference our White Paper "Deploying 415 VAC Power Distribution in North American Data Centers" paper number STI-100-008 posted on our web site.

High Density

Single-power input feed; 36 outlets per enclosure

High Power Distribution

240V/415V 3-phase power; 20/30-Amp power input feed option. Delivers up to 21.6kW.

Input Current Monitor

Precisely measure the aggregate current draw (in amps) on each phase. On-site verification of the input current with the LED digital display. Remote verification via web browser or serial screen.

IP Access & Security

Web interface, SSL, SSH, Telnet, SNMP, FTP, SNTP, Syslog, LDAP, LDAPS, TACACS and RS-232 access


Provide automated SNMP-based alarms or email alerts for power and environmental conditions

Environmental Monitoring

Each Smart CDU supports two external temperature & humidity probes and reports conditions through the user interface without the need for additional IP addresses

Add an Expansion Module

Daisy chain the Smart CDU Expansion Module (CS/CL) for power monitoring of separate “A” & “B” power circuits from a single IP address

Branch Circuit Protection

The Sentry CDU Family meets the UL 60950-1 requirement for Branch Circuit Protections
> UL-489 rated circuit breakers

Input Current Monitoring

Exclusive True RMS current monitoring is critical to preventing overloads in high-density computing environments. LED digital displays on the CDU enclosure report the input current of each phase for simple load balancing.

Temperature and Humidity

The Smart CDU supports two external 10’ (3m) probes. Each of these probes measure both temperature and humidity. Receive SNMP-based alerts or email notifications when conditions exceed denied thresholds.

Linking for Smart CDU (Expansion Modules)

The Smart CDU family now has the capability to daisy chain units together. The Expansion Module provides the ability to link two power circuits under one IP address.
