Replacement Instructions CTAN #337 Focus 1 to 2100/2300 Replacement This replacement instruction is pertinent for Focus 1 drive upgrade Focus 1 Drives Enclosed Chassis 2400-8000 2400-8001 The Focus DC drive series was a popular single motor speed controller for both permanent magnet and shunt field motors 2HP or less. Focus drives were powered from single phase 115vac or 240vac lines typically powering 90v or 180v armatures respectively. The basic unit was available enclosed or in chassis form. Option kits were available to extend functionality and features. The Focus drive was also sold under various other labels such as: 2400-8000 F903 or 612800 WF1000 LWS 25/200 2400-8001 F904 or 612802 WF1050 LWS 25/200C CTAN337 V1.0 1 8/20/2009 Fincor Drives 2300 In this document we will describe the cross over process from the Focus 1 products to our Fincor replacement. Half of the battle with any upgrade, is knowing what you have and what you’re going to need. Many options can be with the Focus 1 such as an Enclosure, M Contactors, Dynamic Braking, and so on. Now we just have to figure out what is in our current drive. CTAN337 V1.0 2 8/20/2009 Knowing what you have The Focus’s model number can be found either on the top of the heatsink or on the bottom of the enclosure. Pictured below is where you model number is located as well as what your label would look like Current Ratting Serial # Model # Enclosed Unit (Viewed form the bottom) P/N 2400-8001 5507051 Chassis Unit Input AC DC Output Armature Field Catalog Enclosure HP 1Ø Max Armature Field Part # Volts Amps Volts Amps Volts Amps 2400- Chassis ¼ -1 120 14 90 10 100 1 8001W ½-2 240 14 180 10 200 1 2400- NEMA 1 ¼ -1 120 14 90 10 100 1 8000W ½-2 240 14 180 10 200 1 When you decide on the proper drive you should always base your selection on the motor’s rated current. The Focus 1 has an output of 10 Amps DC. The Fincor lines of DC drives have other drives available at a lower current output that might be a better match to your motor at a better price. CTAN337 V1.0 3 8/20/2009 Shown below is the Fincor Series of Low horsepower units that will crossover from the Focus 1. CTAN337 V1.0 4 8/20/2009 Identifying Option Kits Your Focus 3 could have different options. Pictured below are the option kits for you to identify. Fwd/Rev “M” Contactor Contactor with DB with DB resistor M Contactor DB Resistor Fwd/Rev Relays DB Resistor Enclosed unit Power On / Off Speed / Current Switch Limit Pot Fwd / Rev Switch Start / Stop Switch (Shown Unpopulated) If the unit that you are replacing has the option to the right, you may not need it for your future application. Except for the 2120 Series, all of the Fincor Single phase DC Drives are Isolated.
