Keep motors warm and moisture-free during extended shut-down periods. AC Supply Voltage 200 to 600 Vac\ HP Ratings 3 to 900 HP Easy to Install Whether retrofitting an existing starter or installing a new one, the MWH Series is easy to apply. Just wire it in parallel to the magnetic starter’s line and load connection, connect the necessary auxiliary contacts and installation is complete. Simple Adjustment Output voltage is factory set to maintaina +5° to 10°C differential above ambient temperature. This adjustment can be used to trim the control as required for each application. Self Protected In addition to built-in fuse protection, the MWH Series features an RC snubber circuit across the SCR which protects it from any rapid rate of change in the system voltage. A metal oxide varistor (MOV) protects the unit against voltage spikes for reliable, maintenance-free operation. Fully Automatic Operation Designed for fully automatic operation, the MWH Series turns on when the motor starter has turned off. A built-in one minute timer ensures that the motor magnetic field has collapsed before it injects DC power into the windings. When the motor is restarted, the MWH Series instantly turns off. No operator interface is required... the MWH Series is in control. Built-in Overload Sensing The MWH Series had an optional shutdown input that can be connected to the N.O. auxiliary contact on the motor starter’s thermal overload relay. This will disable the motor winding heater control, preventing any additional heating in the motor and allowing for a faster motor cool down period. The MWH Series then goes back on-line after the overload relay is reset. Ideal Alternative to Strip Heaters Eliminate the cost and hassle of installing strip heaters into your motors. Simply wire up the MWH Series to generate heat throughout the motor stator windings. The heat is dissipated evenly without the “hot spots” caused by strip heaters. Conduction of heat to the rotor, bearings and shaft is also more effective which means maximized protection for the whole motor. read more

AC Supply Voltage 200 to 600 Vac HP Ratings 3 to 1000 HP Overview Electronic braking stops the load by injecting a controlled amount of DC current into a three phase AC motor. The ABC Series "automatic braking controller" features full-wave DC braking which can be adjusted to stop your load quickly, repeatably and reliably...even if load conditions change. The ABC Series meets the three main objectives that are important in every industry: Maximized Safety, Increased Productivity and Maintenance-Free Operation. Maximum Safety Protect Machinery & Operators The ABC Series is designed to eliminate dangerous coast-to-stop times of rotating machines and equipment. The ABC Series also eliminates the dangerous practice of jamming the machine to bring it to a stop, which can present potential danger to operators and passers-by alike. OSHA and other safety agencies pay close attention to these types of operating conditions and recognize brakes as an important part of a system to guard against potential dangers. The ABC Series is an ideal way to add braking and eliminate dangerous "coast-to-stop" times in your application. Increased Productivity Stop AC Motors Quickly for a Profitable Operation Long coast-to-stop times equal lost production time. Now you don't have to wait forever for the load to come to a stop before you make blade changes or change a tool. Simply stop your equipment using an ABC Series electronic brake for increased efficiency and product through-put. The ABC Series also eliminates any need for "plug reversing." Reversing a load when it is still spinning creates mechanical shock which can cause equipment breakage and extended downtime. Your machinery can now do what it was designed to do... make product at a profit. Maintenance Free Operation Eliminate Costly Down Time Using the ABC Series electronic brake eliminates the wear and tear on mechanical brakes in the system. This means less time and money is spent replacing discs or pads (which is especially important given the "shorter life" material used in today's mechanical brakes). Let the mechanical brake act as a holding brake and let the ABC Series do the stopping. The ABC Series eliminates the common (and also dangerous) practice of "jamming" equipment to stop the load. Expensive blades and tooling are no longer "sacrificed" to stop your motor. The ABC Series for faster, smoother stopping and maintenance free operation. Easy to Install The ABC Series microprocessor insures proper connections and coordinates system operation. Simply wire the ABC Series electronic brake into the motor starter circuit for a cost effective, maintenance-free means of bringing the motor and load to a stop. No isolation contactors, no additional logic wiring...it works right off the motor input leads! It's as easy as A-B-C. Easy to Select The ABC Series units are sized by amperage and should be selected based on the application requirements. "Standard Duty" ratings are sized for 95 - 110% of motor FLA. "Extra Duty" ratings are sized for 150 - 250% of motor FLA. Specify maximum braking current and voltage when ordering. read more
