441-120

Time Mark

The Model 441 Multi-Stage Alternator is designed to control the operating sequence of multi-stage motor/pumping systems. It can also be used to maintain the desired level of pressure-on air compressor systems. Four motor select DIP switches located on the front panel allow the alternator to control a single-motor/pump, two-motor/pump, three-motor/pump or four-motor/pump system. The Model 441 will assure that only the necessary motors/pumps are operating, and that the run time for each motor/pump is approximately equal. Motors are sequenced first-on, first-off. If the motor/pumping demand requires only one motor/pump at a time, the alternator will start the next motor/pump in sequence each time an input switch is closed. Input switches may be float switches, pressure switches, flow switches, etc. , as required by the application.

Potential uses for the Model 441 include water supply systems, sewage disposal plant systems, storage tank filling systems, air compressor systems, irrigation and water recycling systems.

A2652

Time Mark

The Model 2652 3-Phase Monitor is designed to protect motors, pumps, HVAC equipment, air compressors, etc. , by sensing phase loss, low voltage or phase reversal.

With correct power applied, the DPDT output contacts transfer, and drop out when a fault condition or loss of power occurs. An adjustable trip delay prevents nuisance tripping. The restart delay timer prevents short cycling, which is primarily used with HVAC and compressor motors.

The DPDT output contacts allow the Model 2652 to be used in control circuits and alarm circuits. The automatic reset version can be converted to a manual reset, by adding a normally closed switch. The different voltage versions of the Model 2652 can be adjusted over a wide operating range. This unit is housed in an ABS plastic surface-mount case to reduce space requirements.
