Power Adjustable Resistors NRS Series
Date:2019-12-06
These high energy wire wounds are equipped with an adjustable lug, making them ideal for adjusting circuits, obtaining unique resistance values and setting equipment to meet various line voltages.
 
NRS resistors feature a hollow core to permit secure fastening with thru bolts with washers or spring-type clips. They also offer the durability of lead free vitreous enamel, or silicone coating and all-welded construction.
 
Power adjustable resistor NRS series bear below characteristics:
 
Features 
Resistance Tolerance: H(±3%), J(±5%), K(±10%).
Flame resistant and rugged lead coating.
Terminals suitable for soldering or bolt connection.
Adjustable lug supplied. High wattage applications.
 
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 approximately one-half.
Wattage is proportional to this adjusted resistance value.
Adjustability is 10% to 90% of full resistance value.
 
Options 
Adjustable, fixed, or tapped styles are available.
Special terminals available for non-standard applications.
Single and double quick connect terminals can be specified.
Standard lug terminals available with or without terminal hardware.
Non-inductive Ayrton Perry windings can be specified.
Special temperature coefficients, tolerances
 
The power adjustable resistor NRS series is RoHS compliant and lead free. For non-standard technical requirements and custom special applications, please contact us.
