Altronic Research 157250SB OMEGALINE Water-Cooled 250kW, 150 Ohm SB Connector

Introducing the Altronic Research 157250SB OMEGALINE Water-Cooled Load
The Altronic Research 157250SB OMEGALINE is a high-capacity, water-cooled dummy load designed to manage up to 250 kW of power with a resistance of 150 Ohms. It is meticulously engineered for continuous duty across a wide range of applications, from 60 Hz up to 1.8 MHz, making it ideal for industrial and telecommunications applications requiring reliable termination of high power transmissions.

Advanced Cooling for Superior Performance
The OMEGALINE 157250SB utilizes a unique cooling system where coolant enters at the electrically shorted end, travels axially along the center of the resistor tube, and then flows back over the resistor, ensuring effective heat dissipation. This innovative design allows for optimal heat transfer with minimal coolant flow, enhancing the overall efficiency and reliability of the system.

Robust Design and Construction
Constructed with durability in mind, the 157250SB features a housing that doubles as the RF connector with a water housing cap tightly secured by fiberglass pultrusion tie rods. These components ensure a robust mechanical stability and a secure water seal, crucial for maintaining the integrity and performance of the load under varying operational conditions.

Precision Engineered for Demanding Applications
The power dissipating components of the 157250SB include a tubular ceramic substrate coated with a conductive resistive film and silver bands for electrical connections. Contact to the resistor is made through silver-plated spring fingers that allow the coolant to pass directly over the resistive film, ensuring efficient operation and longevity of the load.

Optimized for Versatility and Safety
This model is designed for flexibility in use, with the capability to operate within its power rating in specified positions and recommended water flow rates. Enhanced by safety features including a comprehensive electrical test before shipment, the OMEGALINE 157250SB ensures reliable performance tailored to the specific needs of high-power applications.
