Mengenal aneka informasi perihal Master Clock System

SEIKO QC-5500 Series is a high-precision quartz master clock.
By connecting with an external master clock generating 30-sec polarized
signal output, time correction can be made.
 
Models operating on AC 110 V (QC-55301) and AC 220 V (QC-55302)
are available.

●Master clock function
Up to 90 secondary clocks can be connected to each channel (if the current consumption
of each secondary clock is 12 mA).

●External synchronization function
By connecting with an external master clock generating 30-sec polarized signal output,
the loss/gain of the clock is corrected automatically.
