Input / Temperature rise measurements
(Clause 7.1)
(Clause 7.1)
The apparatus has three modes in supplying voltage
from TF93 transformer for amplifier circuit.
The one is “HIGH mode” of 43 V, and the two is
“MID mode” of 39 V, and the three is “LOW mode” of
26 V, which is controlled by the IC1400 thermal
sensor IC on main heat-sink in amplifier board.
The apparatus is always be started from “HIGH
mode” first, and then changed to “MID mode” or
“LOW mode” electrically by operation of the IC1400
thermal sensor IC when the temperature of the main
heat-sink is exceeding 65 ºC (for MID mode) or
85 ºC (for LOW mode).
The IC1400 thermal sensor IC is UL approved
component according to UL60730-1 and accepted
this component in their position due to comparison
with similar standard IEC60730-1 where there is no
different requirements.
However, please note that the certificate may be
waived by other agency.
