B-185H

Product catalog summary
Product Description: The B-185H housing is designed for Varex Imaging rotating anode inserts with a 133 mm diameter target. It is classified as IEC Class 1 and weighs approximately 28.6 kg. The stator cord is 0.9 m long, and the housing can be mounted using a trunnion or port.
Specifications: The nominal X-ray tube voltage is 150 kV, with maximum cathode and anode to ground voltages of 75 kV each. The grid to cathode voltage is -4 kV. The typical bias voltage for cutoff at 125 kV is -3600 Vdc, and the grid voltage for exposure is 0 Vdc. The maximum X-ray tube assembly heat content is 1,482 kJ. The nominal continuous input power is 250 W without HE-100 and 1,130 W with HE-100, according to IEC 60613:2010 standards.
X-Ray Tube Assembly: Permanent filtration is 1.0mm Al as per IEC 60522. Leakage technique factors are 150 kV, 7.2 mA. High voltage cable receptacles comply with IEC 60526. Temperature limits for storage and transport range from -20°C to +75°C, with humidity levels between +10% to +90% and atmospheric pressure from 70 kPa to 106 kPa. The thermal switch opens at 76.7°C ±2.8°C.
Stator Ratings and Characteristics: The time to full speed of the anode is determined by the power rating of the starter and the weight/diameter of the anode. Varex Imaging stators are rated for regular and high-speed starters, with a time to full speed of 1.3 to 2.0 seconds for 102 mm anode series tubes. Rotor speed must be reduced to 4000 r/min or less within 10 seconds using a dynamic braking device. No more than two high-speed starts per minute are allowed, and the starting voltage must not exceed 600 volts rms.
Stator Drive Frequency: The stator drive frequency varies with RPM: 50 Hz (2800 - 3000 RPM), 60 Hz (3400 - 3600 RPM), 150 Hz (8500 - 9000 RPM), and 180 Hz (9500 - 10,800 RPM).
Wire Color Description: Wire colors are: White - Common, Black - Phase, Green - Phase Shift, Red - Insert center section, Green/Yellow - Housing Ground.
Overview: This document provides technical details on the heating and cooling curves of the B-185H X-ray Tube Assembly. It includes specifications, operational precautions, and notes on heat management.
Specifications: Resistance values for components are 16 Ω for Blanco and 30 Ω for Black-Green. A 10 μF capacitor is specified for 180 Hz applications.
Heating and Cooling Curves: The curves illustrate temperature changes in the X-ray tube housing over time, considering heat inputs from tube power, filament power, and stator power, assuming unrestricted natural convection around the tube housing.
Precautions: Housings with heat exchangers and long hoses should not operate separately from the heat exchanger. Proper coupling is necessary to avoid operational issues. Users should refer to the specific heat exchanger's product data sheet for cooling curves.
Manufacturer Information: Varex Imaging Corporation, with contact details provided for their Salt Lake City, UT, and Charleston, SC locations. Specifications are subject to change without notice.
