A compact design packed full of outlets and options.

Optima RCM 820 Series

The Optima RCM 820 is a series of PDUs for single-phase applications needing as much capability as possible in a 1U chassis. A range of options results in over 60 models to choose from. In addition to current capacity and outlet connector choices, key options include inlet power monitoring (via Ethernet), and the remote EPO and integrated EMI filter package. Remote outlet switching over Ethernet is included on all standard 820 products.

Inlet power monitoring measures volts, amps, watts, voltamps, power factor, and frequency. As part of the EPO/EMI filter option package, the remote EPO option allows a remote control panel to shut down all outlets of one or more PDUs at the same time. The EMI filter includes a broad-spectrum filter on the incoming ac line which helps attached equipment get a clean power signal. Outlet control includes on/off/cycle with user-adjustable delay settings.

Power Monitoring

Inlet power monitoring is a useful option for several purposes, but commonly watched values are amps, volts, and watts. The built-in circuit breaker will protect wiring from an overload, but how do you know if your equipment is close to tripping the circuit breaker? The inlet monitor’s display of amps provides the information you need. Additionally, setpoints can be used to automatically alert personnel that the current load has reached a warning or critical level. Voltage can also be monitored with alerts. Watts is a measure of how much power is actually being used. This can be useful for verifying the equipment capacity needed for backup battery systems or generators.


Outlet Switching

Outlets can be switched manually through web and command line interfaces, or through SNMP. Integration of outlet control in automated processes can be scripted through the RESTful API (an efficient HTTP protocol), or through Telnet or SNMP.

Each outlet may be user labeled to reflect its purpose or what it is connected to. Each outlet includes on/off/cycle commands with individually adjustable delays. Each outlet is configurable to be on or off at startup, or restored to whatever the last known state was prior to shutdown. Logging of switch events can be enabled or disabled, and even configured to send alerts.


Remote EPO

The Optima remote EPO feature is primarily designed for use with a Marway remote EPO panel such as the Commander UCP 3500. A Commander panel may be connected to one or more PDUs, and thereby trigger an EPO event for several racks in unison.

In the 820 Series products, the remote EPO feature disables all eight outlets on the rear panel, but not the unswitched outlet on the front panel. The firmware detects the EPO event, updates the outlet states, and can optionally send an alert over email, SMS, and/or SNMP.

EPO button is part of an external remote panel. The 820 Series includes a connector for the remote panel.
