ELECTRONICS MCE/C INVERTER CIRCULATING MCE/C 11 - MCE/C 15 - MCE/C 22 MCE/C 30 - MCE/C 55 The new MCE/C inverters are the latest technological challenge in the DAB inverters universe. They constitute the new generation of inverters for use with circulator pumps and stand out for ease of use, power, and simplicity of installation and management. MCE/C inverters are designed for use with circulator pumps to enable simple control of differential pressure, thereby adapting pump performance to match effective system requirements. The solution of mounting on the motor base greatly simplifi es installation of the pump with MCE/C in minimal times. Ease of programming is guaranteed by the use of an interface similar to DAB Dialogue and a graphic display. MCE/C inverters feature dual microprocessor architecture to guarantee maximum efficiency and reliability. Sturdy and reliable construction is combined with modern and innovative styling to complete the product also in terms of aesthetics. MCE/C inverters protect the pump thanks to integrated safety devices. They are also able to prolong the useful lifetime of the pump thanks to the elimination of water hammer and rotation of the pump at the minimum rpm necessary to meet the requirements of the user. Last but not least, these inverters save power by keeping pump consumption to the minimum levels strictly necessary to meet user requirements.

ELECTRONICS MCE/C INVERTER ENERGY SAVING Reducing motor speed, even marginally, can lead to an appreciable reduction in power consumption because the absorbed power of an electric motor is proportional to the rpm cubed. For example, a pump powered by the mains that runs at approximately 2950 rpm, will run approximately 20% slower (i.e. at 2360 rpm) when fed with a 40 Hz supply, leading to a saving of 40% in terms of absorbed power. The motor speed reduction increases pump life signifi cantly, thanks to the reduction of mechanical stress. Pump performance in relation to variations in rpm...

INVERTER OPERATING MODES All the functions listed below can be consulted by all users (even the least skilled) by just scrolling through the MCE/C menu. Calibration and parameter modifi cation are protected functions, permitted only to skilled users. Constant differential pressure control mode ΔP-c ΔP-c control mode keeps the system’s differential pressure constant at the H value set (setp) as the fl ow rate varies. This is the standard control mode, for normal use. It can be set directly from the MCE/C’s control panel. The inverter maintains the differential pressure (H setp) constant as...

ELECTRONICS MCE/C INVERTER CONNECTIONS ON MOTOR 1 Hydraulic diagram The MCE is installed on the motor base. The inverter can operate both vertically and horizontally. 2 kits are available for assembly on the motor: Tie-rods: These are connected to the MCE dissipator and fan cover. They require a solid fan cover able to withstand the weight of the inverter, i.e. secured by means of bolts or screws. Fan cover kit: The fan cover kit is used in all situations where the fan cover is not sufficiently solid or strong enough to withstand the weight of the inverter. TWIN OPERATION Groups of up to 2...
