Conzerv EM3460 Smart Demand Controller

The Conzerv EM3460 is a comprehensive three-phase electrical instrumentation and load management facilities in a compact and rugged panel-mounted package.  Offering power and energy monitoring at feeders and individual loads. In addition, the EM3460 offers Demand Control. 

The Conzerv EM3460 offers high accuracy, reliability and ruggedness, as well as real value for money. This next-generation micro-processor based instrument monitors over 25 vital parameters and replaces over 20 individual transducers and meters and records more than 200 items of information, for comprehensive Load Management in 3-phase commercial and industrial applications.  These are quickly accessed by seven Smart-Keys on the front panel via a simple user interface, and displayed on a large, 14 mm, high visibility LED display.  Also, features an anti-glare front panel for improved readability.

Includes all the benefits of the Conzerv EM3480 such as; 

• Offers comprehensive power and energy monitoring at feeders and individuals loads;
• Retrieves previous energy reading to cross check utility meter readings or electricity bills;  
• Analyzes loading patterns;
• Visualizes unbalances in system; 
• Checks for wrong connection, reversed phase sequence, deteriorating power factor compensation on one of the phases etc.
• Offers Demand Monitoring
• Ensures automatic synchronization of demand with utility meter
• Displays Max demand along with date and time of occurrence
• Helps to set realistic demand target

Benefits:

• Predictive feature enables prior indication of crossing demand
• Facilitates tripping of non-essential loads
• Analyses electrical faults & planning of load schedules
