INVERTER PRESSURE PUMPS MCE/P is the leading edge of teh Dab Inverters family and are ideal for professional and very severe applications. They can drive pumps of up to 15 kW. These units combine the simplicity with the robust design and power of an inverter drive. MCE/P are mounted on the pump, and are equipped with pressure sensors and the optional flow sensors as required. The use of a flow sensor, moreover, allows a better pressure regulation. The MCE/P can easily be set up in booster sets,thanks to a standard wire cable connection. Comfort, energy saving, protections and simplicity are the keywords of this professional series. The MCE/P units are air cooled. The MCE/P can be easily installed in existing systems and can operates with all pumps Facility to create sets with interchange of up to 8 pumps. MCE/P 11 - MCE/P 15 - MCE/P 22 MCE/P 30 - MCE/P 55 • Self-ventilated panel-mounting inverters for hydraulic pumps. • For three-phase pumps up to 3HP - 2,2kW (model MCE/P 11 – MCE/P 15 – MCE/P 22) For three-phase pumps up to 7,5 HP - 5.5 kW (model MCE/P 30 – MCE/P 55) . For three-phase pumps up to 20HP – 15kW ( MCE/P 110 – MCE/P 150). • OLED graphic display. • Input power supply 1 x 230V 50-60Hz (model MCE/P 11 – MCE/P 15 – MCE/P 22) Input power supply 3 x 400V 50-60Hz (model MCE/P 30 – MCE/P 55 MCE/P 110 – MCE/P 150). • Electric pump nominal frequency 50-200 Hz. • Control range in accordance with the sensor utilised, with standard range of 1-24bar. • Protections against voltage surges. • Adjustable overload protection. • Extended connectivity. • Protection rating: IP55. • Dry run protection. • Short circuit between output phases. • Overtemperature protection. • Anti-seize and anti-frost function. • Costant pressure.

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 Pump rpm n has a very signifi...

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 pumps can be created....
