Main features MDC-4 Basic option Analyzer to control the maximum demand for each level MDC-4 xx Built-in power analyzer. xx Demand management that can control up to 4 local loads. xx Calculations on scrolling window. xx Measurement of electrical parameters of the installation. xx Activation by level above setpoint. xx Programming of the contracted power. xx Programming of 4 different alarm levels for the outputs. xx100…240 Vac power supply. xx Information on load operating time. xx Current measurement with MC transformers. xx Window for displaying power control parameters. xx Compact dimensions. New Maximum Demand Control by level Managing demand 365 days a year MDC-4 is designed to control the maximum demand of an installation for each level. The unit performs analyzer functions and therefore also calculates the energy consumed. Disconnecting non-priority loads at maximum demand times when you are close to the contracted power avoids penalties on your electricity bill.

Analyzer to control the maximum demand for each level Level control optimises the installation because it allows the maximum number of loads to be used simultaneously, avoiding any power excesses which would normally result in high penalties. Load management The unit controls the disconnection of up to 4 relays. Loads are disconnected by level. For example, if the unit configuration for each of the relays is as below, the unit's response will be as shown in the attached graphic. • • • • 70% of the configured power 80% of the configured power 90% of the configured power 95% of the configured power...
