- Page 6 , the danger of an electrical shock can be minimized. Take the same care in disconnecting the input cable. Use AC-power source of LDC-823A at 50 - 60Hz, within 10% of rating voltage. e of Caution: Excessively large or small AC voltages may induce erroneous operation.
- Page 9 Input sensitivity by duty ratio With LDC-S23A, trigger level of Schmidt circuit is set in such a way so that it will the maximum sensitivity against the signal of 50% duty ratio, such as sine wave, triangular wave and rectangular wave. When the duty ratio is reduced, the DC level of the signal added to Schmidt circuit will vary as shown in Fig.
