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. 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.
