STANDARD SIZE RHEOSTATS - 6", 8", 13" TYPES S and M

Vitrohm pressed steel rheostats furnish a simple, accurate and economical method of field control. They are universally applied for adjusting generator, alternator and exciter field 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. 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 voltage.
  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 accessory. If back-of-board mounting, state panel thickness
  6. Manual or motor drive.
  7. Optional or special features required.
