Vitrohm pressed steel rheostats furnish a simple, accurate and economical method of field control. They are universally applied for adjusting generator, alternator and exciter fiel currents to obtain variations in output voltage and for field control of adjustable speed D.C. and synchronous motors. Other typical applications include heater, furnace, battery charging and other controls.

4" RHEOSTATS-300 Volt Max. Service 

Vitrohm 4" rheostats for 300 volt max. service are specially designed for field and other control applications. 

DANCER ROLL RHEOSTATS-6, 8, 13 inch Types S and M

Series 60DR rheostats are for dancer roll service on multi-motor drives where relative speeds between the motors must be maintained within specified limits. Typical applications of these field control rheostats include textile, paper, steel mills and others in the process machinery field.

MOTOR DRIVE ACCESSORIES-Type SMD

Type SMD Accessories are for use with 8" or 13" rheostats where motor driven operation is required. Standard assemblies can be applied to drive up to four plates simultaneously.

 

For larger 15 1/2" and 18" rheostats as well as the 13" size, a Type LMD large motor drive is available on order.

 

TO ORDER RHEOSTATS

* Consult Customer Service for price and availability.

* If replacing an existing unit, have the "K" number or serial number available.

FOR GENERATOR FIELD CONTROL SPECIFY:

  1. Whether self-or separately-excited. If separately excited give voltage, field resistance (hot or cold) and minimum field current. If self-excited state maximum field current and field resistance (cold) under no load conditions, or peak generator voltage and field current at peak voltage and minimum generator voltage with field current at minimum volatge. 
  2. Open or enclosed
  3. Type contacts
  4. Type accessory.
  5. Manual or motor drive
  6. Optional or special

FOR OTHER APPLICATIONS SPECIFY:

  1. Maximum and minimum current
  2. Rheostat resistance.
  3. Open or enclosed
  4. Type contacts
  5. Type accesssory. If back-of-board mounting, state panel thickness
  6. Manual or motor drive.
  7. Optional or special features required.
