High Starter Power Suitable for
Application Loads Involving Brief Current Surges
Preview
DST Power Resistor Construction:
● A tubular ceramic insulator has a fixed number of windings and is wound with heavy alloy wire as
a resistance element. The staggering wound is made according to the desired resistance value,
followed by the placement of the component mounts.
● Metal parts are heavily plated to prevent oxidation at high operating temperatures and to prevent
corrosion. DST’s high power rating (500W~1000W) and low resistance value (0.5Ω-7Ω) provide
applications high starter power and capacity.
● This power wirewound resistor is high temperature-resistant, dissipates heat well, has a low
temperature coefficient that varies in direct proportion, and is suitable for application loads involving
brief current surges.
Applications:
● Typical applications for power strater resistors in motor starters, load measurements, industrial
machinery, electric distribution, dynamic braking, load dumping, current limiting, instrumentation,
and automation control installations.
● Due to the set number of windings on the ceramic form, the resistance value range is relatively
low. Tolerance is ±10% and this product is available in various shapes or in resistance boxes.
The DST Series is RoHS compliant and lead free. For non-standard technical requirements and special
applications, please contact us.
