Other sizes available; contact Ohmite. Also available in low cost Centohm or Silicone coating; contact Ohmite.
Adjustability
10% to 90% of full value. Wattage is proportional to this adjusted
resistance value.
Coating
Lead free vitreous enamel. Large models (500 watts and up) are
supplied in Silicone Ceramic. Also available in low-cost Centohm
coating; Consult factory.
Core
Tubular ceramic.
Terminals
Solder coated radial lug. RoHS solder composition is 96% Sn,
3.5% Ag, 0.5% Cu
Adjustable
terminal
Nickel plated steel. (Screwdriver type adjustable lug supplied
standard. Other types, including silver contact units, available.)
Derating
Linearly from 100% @ +25°C to 0% @ +350°C.
Tolerance
±10% (K)
Power rating
Based on 25°C free air rating. The stated wattage rating applies
only when the entire resistance is in the circuit. Setting the lug at
an intermediate point reduces the wattage rating by approximately
the same proportion. Example: If the lug is set at half resistance,
the wattage is reduced by approx. one-half.
Overload
10 times rated wattage for 5 seconds.
Temperature
coefficient
±260 ppm/°C
Dielectric
withstanding
voltage
1000 VAC: 12 to 100 watt rating. 3000 VAC: 175 and 225 watt rat-
ing (measured from terminal to mounting bracket)
Max. amps
To calculate, use the formula √P/R.
210 Series
Dividohm® Vitreous Enamel
Adjustable Power
Choose Ohmite’s 210 Type adjustable resistors for
applications requiring settings at different resistance
values. These wirewound resistors are equipped with
an adjustable lug, making them ideal for adjusting
circuits, obtaining odd resistance values and set-
ting equip ment to meet various line voltages. 210
Type resistors feature a hollow core to permit secure
fastening with spring-type clips or thru bolts with
washers. They also offer the durability of lead free
vitreous enamel coating and all-welded construction.
Mounting brackets not included with resistors.
