Maxchek 400 is a smart maximum demand controller with standard size 96x96 mm specifically designed for industries to keep a check on their maximum demand. It gives an alarm when demand approaches a preset value and also switches off non-essential loads in a pre-programmed logical sequence. This predictive maximum demand controller (MDC) allows stage wise load restoration to maximize the use of a sanctioned load. Maxchek 400 is most suitable for the demand control of industrial consumers, HT consumers and commercial establishments. It also support ethernet module for communication.

Application:

• Commercial and industrial sanctioned demand monitoring & controlling applications
• Control panels for complete plant demand controlling
• Demand management for commerce and industry

Benefits:

• Easy interface with external devices through built-in Modbus (RS-485)
• Detachable connectors for easy installation
• Three relay and one alarm output
• Suitable for star or delta connections and for low or high-voltage applications
• Alarm output for audible indication.
• Field-configurable CT/PT primary and secondary values using push-buttons
• Calibration LED for on-site accuracy check
• Configurable software (ConfigView) for reading of parameters and load survey
• Shift wise demand configuration

Features:

• Two modes of programming - preventive mode (only alarm no control), predictive mode (alarm and automatic control)
• Predictive demand control to forewarn, take corrective measures and check maximum demand crossovers
• Multi-level (phase wise and shift wise) priority based automatic load control mechanism to disconnect lowpriority loads in phased manner
• Configurable demand integration period for sliding and fixed type
• Optimised load disconnection time
• Online load planning by continuously indicating loads that can be added or need to be disconnected (within safe operating limits)
• Check meter with accuracy class 0.2s,0.5s and 1.0
• Auto and push button display
• An user friendly software to program and monitor
• Control outputs for alarm and trip applications - it provides 3 control and one alarm outputs, in the form of potential free contacts
• Large four-line seven-digit display (9.7 H x 5 W mm) with quadrant identification section and bar graph for instantaneous power-level indication
• Ethernet gateway module for easy integration
