Substitution Principles And Precautions For Changhong GP02, GP02-1, GP11 Switching Supply Power
The GP02/GP02-1/GP11 switching power supply is based on STR-X6759N+STR-V152. The switching power supply consisting of the STR-V152 generates a 5 V / 5 A voltage, which is available in both 5 V / 1 A and 5 V / 4 A modes. The 5 V / 1 A voltage is provided to the CPU on the main signal processing board and the 5V / 4A voltage is applied to the signal processing circuit. During standby, the 5V / 1A voltage won't be controlled by the on/standby signal and the 5V / 4A voltage will be turned on/off by the main signal processing board.
The switching power supply composed of STR-X6759N produces two sets of voltage: One is 12 V/24 V. If the power supply is the GP02/GP02-1/GP11 switching power supply, the output voltage will be 12 V; If the power supply is the GP09 switching power supply, the output voltage will be 24 V. The two groups of voltage are both provided to the main signal board audio amplifier circuit. The other set of voltage is 24 V, supplied for the LCD inverter. When the computer is standby, the CPU on the main board issued the low level standby instruction of 0 V. The switch power supply of STRX6759N will be shut down, and the 24 V voltage supplied for the inverter and the 12 V/24 V voltage supplied for the sound amplifier will disappear simultaneously.
Substitution principles of GP02, GP02-1, GP11 switching power supply: In China, GP02, GP02-1, GP11 switching power supply could be mutual substituted directly. They can also be substituted with the purchased e01 FSP205-4 (C), e01, FSP179 FSP205-4-4 f01 switching power. If the electric supply is 110 V, only gp02-1, fsp205-4e01 and fsp179-4f01 can be used.
