| Isoration Type DC
Amplifiers |
| The Isoration Type D.C. Amplifier can be used for such
purposes as, measurement in case of potential (relative to earth) difference,
blocking of in-phase noise, and prevention of grounding loop. |

| · |
SA-144 consists of a power supply unit (SA-144P) and a
two-channel amplifier unit (SA-144U), and can be extended to a maximum
24 channels, without using a multi-channel case. |
| · |
It realizes the specifications on each channel, including
withstand voltage (in-phase rated voltage CMV) 1000V(1min.)/400V(continue),
isolation mode rejection ratio (IMRR) 100db or more (at DC - 60Hz, GAINx100). |
| · |
Calibration voltage is built into each channel. |
| · |
Values phase characteristics and uses a 3rd Bessel type
low path filter (five-step change). |
| · |
Frequency characteristic of DC - 30kHz +0.5/-3dB (at LPF:PASS). |
