The above figures are ex-
amples for reference.
THM/PRD/PRV [Remote control code: 7A—0B (CD SKIP –)]
(Detection of the temperature of the heat sink and protection function)
THM: Detection of the temperature of the heat sink
(Normal value: 6~40) 0.3V~ 2.0V (reference voltage)
At 5% or less, the protection function works to turn off the power. At more than 40%,
possibility is that there is an error in the temperature detection system.
PRD: Protection value for DC detection (Normal value: 1~13) 0.05V~ 0.65V (reference voltage)
When the value is out of the normal value range, the protection function works to turn
off the power.
PRV: Protection value for power voltage (Normal value: 5~15) 0.25V~ 0.75V (reference voltage)
When the value is out of the normal value range, the protection function works to turn
off the power.
