 | ENERGY SAVINGS - The Wattmiser recovers the slip power normally lost as heat in other
slip drives and returns this power back into the incoming line. This results in
substantially reduced power costs. |
 | INCREASED EFFICIENCY - The high efficiency of the Wattmiser drive offers dramatic
savings in energy consumption over slip type drives such as the wound rotor motor with
resistor control, eddy current drives and hydraulic couplings. (FIG 4) The Wattmiser
offers high efficiency with far less complexity than adjustable frequency drives because
it uses a simple line commutated inverter. |
 | INFINITELY VARIABLE SPEED CONTROL - By regulating the rotor voltage and current, the
Wattmiser provides infinitely variable motor speed matched exactly to the system speed
requirements. |
 | REDUCES PEAK DEMAND - The Wattmiser limits the inrush current to a minimum level thereby
reducing utility peak demand charges. |
 | LONGER MOTOR LIFE - By soft start and infinitely variable speed control, the Wattmiser
reduces motor heating, bearing wear, and coil flexing since the rotor torque is limited to
that required by the load. |
 | FLEXIBILITY - In pumping applications duplex, triplex or quadraplex systems may be
provided so that pumps are started, stopped and speed controlled automatically to meet the
system flow requirements. Provision is made to alternate the lead pump and thus provide
even wear. |
 | RELIABILITY - All printed circuit boards are burned-in to eliminate infant mortality.
The complete Wattmiser controller is thoroughly tested and run at the factory before
shipment to the site. All components are conservatively rated. |
 | MAINTAINABILITY - The Wattmiser is a solid state control requiring minimum maintenance.
Printed circuit boards are plug-in design for quick removal and ease of maintenance. |
 | EXPERIENCE - Marathon Electronics is the industry leader in application and design of
wound rotor slip recovery systems. Hundreds of Wattmiser have been installed providing
owners with years of trouble-free, energy conserving operation. |
