Improve your reliability and save on operation cost, by eliminating outages, system failures and unplanned maintenance.
Achieve this by exchanging your old DC-motors to frequency-controlled AC-motors powered by a complete system. A solution that caters to both your AC and DC power requirements. All this with a system which is easy to maintain by your own staff.
For motor loads, AC UPS and DC Motor based-backup systems are not optimal as reliable backup solutions. KraftPowercon’s Uninterruptible Motor Drives solution UMD™ is the most effective solution to secure pumps, gates and other motor loads.
KraftPowercon offers a complete portfolio covering solutions for motor, AC and DC loads.
Supplying motors with the correct power during critical operation means the difference between profit and downtime costs, the difference between running machines and mechanical failures, and the difference between planning ahead and planning urgent field service.
UMD™ systems utilize proven and field tested uninterruptible power supply principles that achieve unmatched reliability.
UMD™ utilizes field-proven, high-quality VFD’s. All the advantages of VFD operation also applies to the UMD™. That includes: limiting start currents, starting at maximum torque, precise speed control, energy savings etc. At Direct On Line start of an induction motor, the inrush current can be up to 9 times of the nominal current. The UMD™ with its internal VFD solves the problem and realize the motor’s full potential.
The UMD™ system is designed to remove all Single Points of Failure. Traditional UPS systems must be doubled or excessively oversized to achieve the same safety level.
UMD™ is delivered as one complete MCC-unit. Type tested according to IEC, UL, CSA and other applicable standards. The system has single or redundant mains input breakers, battery charger, AC and DC busbars, and the required motor drive outputs. In addition, it can be extended to backup all AC and DC auxiliary loads.
As a result of this several complex engineering activities including battery sizing, power loss calculations, motor protection settings, fuse selectivity in distribution board, can be eliminated. It also allows for fast and straightforward installation and commissioning that can be performed by local technicians.
UMD™ is a system intended for the uninterruptible operation of three phase AC-motors. It is based on frequency converters that can be powered not only from the existing mains drive but also from batteries. The system contains the required number of drives, battery and internal distribution of AC, DC power and control circuits. The system is fed by one single or dual mains supply. Each output to the electrical motor is fully controlled by bus or hardwired interface and protection of cable and motor.
The Power Center is a complete modular system for highly flexible output power and easy service. Complete with rectifiers, batteries, battery fuse box, distribution boards and monitoring mounted in a cabinet. The batteries can also be placed in their own rack next to the cabinet. The system has a modular design to enable easy adaptation to the existing needs of the installation.
