For increased power requirements, the HS2-MPX is designed for normal and high speed rotation of x-ray tube anodes.



  • 3 Tube operation
  • High efficiency drive
  • Modular construction for quick and easy servicing
  • Easy universal interface
  • LED's at all external inputs
  • 16 Pre-programmed time delays
  • Very quiet acoustically and electrically
  • Microprocessor control for logic reliability
  • A service routine for ease of x-ray tube calibration


Technical Specifications:


Weight: 70 lbs. (starter and cabinet) Shipping Weight: 86 lbs.

Power Supply:

208/240 VAC single phase 15 amp “R” stator -or- 30 amp “Q” stator - UL approved

-or- 277 VAC single phase 12 amp “R” stator -or- 20 amp “Q” stator - not UL approved

Stator Power and Operation:

  Low Speed (60HZ) High Speed (180HZ)  
Start Run Start Run AC Brake DC Brake
R 220V 54V 440V/490V 100V 220V 60VDC
Q 220V 52V 340V 60V 220V 50VDC

Stator connections made directly to a terminal strip in the unit

440V/490V is selectable at time of installation

Brake Sequence:

High speed to low speed = AC brake

Low speed to stop = DC brake (optional), Activated by switch on board

*Starter will not change over until spinning tube is braked

Logic Inputs:

Input opto-isolators require 5 - 24V AC or DC, or 110V AC or DC from generator

If generator power not possible, +24V DC available from starter

Command Inputs:

1. Rad Prep - usually from the handswitch circuits

2. Fluoro - usually from the footswitch circuits

3. High speed select - usually from the tube protector

4. Spot film transfer - usually “RL” from the spot filmer

5. Tube 2 select

6. Tube 3 select

Logic Outputs:

(Both output relay contacts: 3 amps max at 30V DC or 250V AC)

1. Standard X-ray inhibit interlock - N.O. contacts close during run

2. Auxiliary relay - N.O. & N.C. contacts - switch programmable to energize for:

a) High speed selected (for possible tube protector use)

-or- b) Brake on (for filament circuits - tube changeover inhibit)

Acceleration Times:

16 - (low accel / high accel / low to high accel) time combinations switch selectable

*Time for each of the three tubes independently selected

Additional Switch Programming:

1. High speed hold (hangover) times:

0, 20, 40, 60 sec, 10, 15, 20, 30 min.

2. High speed for all spot films

3. 0.75 sec exposure inhibit between high speed hold and spot film transfer.

*This allows time for filament warm-up and cassette vibration dampening.

4. “Rad prep” or “high speed select” input starts anode rotation
