C451-2105-15  5HP, 1PH
C451-2105-35  5HP, 3PH

The rebuilders alternator tester.  Heavy duty in every aspect from its unique full loading capabilities to its heavy duty
 variable speed operation.  Test all type alternators 12/24 volt, negative or positive ground, passenger types to
heavy duty diesels including the late type alternator. 

Free spin starters both domestic and foreign.

1    C451-2105-A15 & C451-2104-A35  Same as C451-2105-15 & C451-2105-35  but features air operating vise with two heavy duty air cylinders, one to hold unit being tested and one to tighten the alternator/generator belt
2    440V or 575V models available

•    Electronic variable speed control (inverter) with speed range controlled by potentiometer
•    Speed range from approximately 800 to 7,000 RPM to make tests at OEM recommended output speeds & low RPM cut-in speeds
•    Heavy-duty motor designed for electronic variable speed inverters that ensure energy efficiency and quiet operation
•    Off/forward/reverse motor switch
•    Variable electrical load control and fixed load control to simulate the entire charging range of the alternator while safely dissipating output current through a bank of heavy duty wire wound resistors which are fan cooled.  This feature eliminates the burn out problem associated with the old-fashioned carbon pile loads
•    Diode ripple lamp shows if main diodes are shorted or open
•    Diode trio lamp simulates dash light operation on Delco 10SI and similar integral alternators, including the late model alternators
•    Oscilloscope plug connections
•    Alternator harness for easy hook up of foreign and domestic alternator test leads
•    Serpentine/V-belt combination pulley
•    Heavy duty D.C. power contactors
•    Heavy duty field rheostat
•    ON/OFF mains lamp
•    Heavy duty hook up leads and clamps
•    Modular design for easy servicing
•    Four 4 1/2” pivot and jewel analog meters
•    Voltmeter: 0-18/36 volt scale, shows alternator output voltage/integral voltage regulator controlling voltage
•    Ammeter:  0-250 scale show output amperage
•    Ammeter: 0-200 scale shows battery charging amperage, i.e. amount of current going into battery and not into load
•    Ammeter: 15-0-15 scale shows rotor draw where applicable
•    Digital tachometer shows alternator RPM adjustable to compensate for pulley size
•    A/B circuit switch
•    12/24 voltmeter range switch
•    Voltmeter external switch for testing stator voltage at “STA: and “R” relay terminal
•    Alternator output leads are dead until motor is turned on, or until battery ON switch is switched to ON position
•    Battery ON switch for constant battery voltage, if needed
•    Fully copper wound class B insulated transformers coated to resist moisture penetration
•    Sturdy heavy duty cast iron mounting vise with alternator bracket  for quick mounting and removal of alternator
•    1 1/4” hold down screw securely holds down heavy duty alternators, generators and starters
•    Hinged belt guard
•    Free running 12/24 volt no load starter test
•    IGN “R” lamp to indicate proper “R” terminal operation on Delco starters
•    5HP
•    Single or 3 Phase 230 Volt
•    Electronic variable speed Control (Inverter)
