UXP800 series power resistors

Detailed Product Description

UXP800 series power resistors

For variable speed drivers, power supplies, control devices, robotics, motor control and other power designs, the easy mounting fixture guarantees an autocalibrated pressure to the cooling
plate of about 120 to 160 N.
General Characteristics
Electric support:High alumina ceramic metallized with EBG ALTOX film on the bottom for better heat transfer and optimum discharge.
Encapsulation:Special resin filled epoxy casing with large creeping distance to mass, large
air distance between the terminals and high insulation resistance (CTI 600).
Resistance Element:Special design for low inductance and capacitance values. The element
employs our special METOXFILM which demonstrates stability while covering high wattage and pulse loading.
Contacts:Easy load connecting with M4 or M5 screws.
Connector height (M+N) available from 25 to 42mm.
Various sleeves for increased creeping distance up to 85mm or potted cable connections are available on special request Materials in accordance with UL94-V0
