Product catalog summary
Overview: The document describes the HPR series of high power resistors manufactured by KRAH Elektronische Bauelemente GmbH. These resistors are designed for high power applications and are characterized by their intrinsic safety, high withstand strength, and increased impulse solidity. They are encapsulated in an aluminum profile to protect against dirt and accidental contact.
Specifications:
  • Types: HPR 60 to HPR 500, available in horizontal (H) and vertical (V) styles.
  • Housing: Anodized aluminum.
  • Dimensions: Vary by type, with specific tolerances for length, width, and other dimensions.
  • Resistance Range: From 0.1Ω to 7.5kΩ depending on the model.
  • Tolerances: Available in 1%, 2%, 5%, and 10%.
  • Temperature Coefficient: Between 80 to 200 ppm/K.
  • Insulation Resistance: Greater than 20 MΩ.
  • Operating Voltage: Up to 1000 VAC for higher models.
  • Testing Voltage: Up to 4000 VAC for one minute.
  • Power Rating: From 60W to 500W.
  • Protection Level: IP 65.
  • Temperature Range: -40°C to 200°C.
Performance and Testing:
  • Derating: Linear from 40°C to 200°C.
  • Long Term Stability: 3% over 1000 hours at 40°C.
  • Environmental Testing: Includes long-term environmental tests and rapid temperature changes with a 2% variation.
  • Vibration Load: Safe up to 40 m/s².
  • Terminal Strength: Can withstand a tractive force of 100 N.
Customization: Customer-specific requests for leads, taps, inductivity, capacity, and thermal control are available upon request.
Ordering Example: HPR 60 H 10R K 300 indicates a 60W horizontal resistor with 10Ω resistance, 10% tolerance, and 300mm lead length.

Encapsulated high power resitors HPR 60 - 500-1

Hochlastwiderstand im Aluminiumprofil High power resistor in aluminium profile Résistance de puissance très forte dans un profil en aluminium Hochlastwiderstände vom Typ HPR sind eigensicher, hochbelastbar und bieten eine hohe Spannungsfestigkeit. Die Typenreihe HPR zeichnet sich durch eine erhöhte Impulsfestigkeit aus. Ihre kompakte Form sowie die Ausführung ihrer Anschlußelemente erleichtern die Befestigung und Montage der Widerstandselemente bei ihrer Anwendung. Die vollständige Kapselung gewährleistet Schutz vor Verschmutzung und zufälligem Berühren der spannungsführenden Teile. Für weitere Informationen sehen Sie bitte die allgemeine Beschreibung zur jeweiligen Produktgruppe. The resistors of the type HPR are intrinsically safe high power resistors and have a high withstand strength. One of the remarkable features of the type series HPR is an increased impulse solidity. Its compact form, as well as the execution of the elements of its leads, make the fixing and mounting of the resistor elements easier when using. The complete metal protection guarantees a protection against dirt accumulation and accidental contact with the hot parts. For further information, please see the general description of each group of products. Bauform / Style / Modèle V Type Bauform Style Modèle Les résistances du type HPR sont des résistances à sécurité intrinsèque qui ont une puissance et une rigidité diélectrique très élevées. La série du type HPR se caractérise par une résistance particulièrement forte aux impulsions. Sa forme compacte, ainsi que l’exécution des éléments de sortie, simplifient la fixation et le montage des éléments de la résistance lors de son utilisation.
