Advantages
Increased Safety
The DIRIS MCM is designed to improve installation safety and meets electrical code requirements:
- Built-in optional disconnect provides path to quickly and easily service the meter independently of other circuits.
- mV CT connections, can be connected and disconnected under load.
- No user-direct access to dangerous high voltages, keeping instrumentation engineers safe.
- Retained fasteners, ensuring screws stay securely in place and don‘t fall inside electrical panels.
Easy installation
- Wall or top cabinet mounting.
- Built-in 1” conduit holes - 3 at the bottom and 3 at the top of the meter.
- Push-in terminals for current sensors, no tools required!
- Clear visible numbering of CT inputs, with color coded terminals that match CT output lead wires.
Easy commissioning
- Configuration with a simple and intuitive PC application via a direct USB connection.
- ONE IP address and Modbus slave address supports the entire meter, simplifying network integration pain points.
- CT configuration correction algorithm helps eliminate user wiring and setup errors while reducing
downtime.
Industrial Design
- Aluminum bonded enclosure.
- Internal fuse protection of each hot leg.
- Fuses can be replaced safely for maintenance.
Compact
- The most compact high density multicircuit meter on the market, in an enclosed format.
- Ideal for retrofitting electrical distribution centers with limited wall space.
Wireless communication
When associated with the Socomec RF interfaces, DIRIS MCM power meters from different locations throughout a facility can communicate their measurements wirelessly to a central Hub, which significantly reduces installation and wiring time.
Applications
- Data center - Power availability for servers
- Building - Metering and sub-billing
