Marine - Shipboard Synchro Signal Amplifiers (SSA)
Description:
The Synchro Signal Amplifier is in actuality a synchro data repeater. It accepts synchro data from remote transmitters, aligns associated output synchros to electrical correspondence with the remote transmitters, and retransmits the data to other equipment. Synchro Transmission is increased by the use of larger output synchros than the remote transmitters.
Synchro Signal Amplifier Types:
Type E SSA – The Type E Synchro Signal Amplifier requires 60 Hertz input data and supply power.
Type F SSA – The Type F Synchro Signal Amplifier requires 400 Hertz input data and supply power.
| TYPE DESIGNATION - Example: Type F - Mark 31 - Model 8A | |||
| Type F | Mark 31 | 8 | A |
Input & Supply Type E = 60 cycle |
Speeds & Input Supply 27-1 & 36 speed - 60 cycle supply 31-1 & 36 speed - 400 cycle supply |
Manufacturer 8 - Henschel |
Output Synchros Letter designates output synchro complement; for example, "A" indicates two Type 6HG and two Type 31TX4 synchros. |
Input and Output Synchro Data:
| Type Amplifier |
Input | Output |
| Type Frequency Speed | Type Frequency Speed | |
| E | 18CT6 60 1 or 2 18CT6 60 36 |
6HG or 37TRX6 60 1 or 2 6HG or 37TRX6 60 36 37TRX4 400 1 or 2 37TRX4 400 36 |
| F | 18CT4 400 1 or 2 18CT4 400 36 |
6HG or 37TRX6 60 1 or 2 6HG or 37TRX6 60 36 37TRX4 400 1 or 2 37TRX4 400 36 |
Note: The output synchros listed above are the largest size that may be used. Smaller size synchros may be installed by use of adapter rings and change gears which are normally not furnished with the equipment. Synchro differentials or control transmitters may be provided as output synchros in lieu of synchro generators.
