Taida Yu- HY-2414 - J5, j7: j7 open: j5 closed start power, disconnect the power is turned off, each time the power must be re-opened J5 and then open the power to open. J1: battery interface battery positive and negative 5557-2p j2: Input power interface 5557-4P J3: Output power interface 5557-4P J4: Motherboard on / off control output.
Vr1: charge current regulation potentiometer vr2: charge voltage regulator potentiometer VR3: battery start threshold voltage regulator potentiometer VR4: battery undervoltage protection threshold voltage regulator potentiometer VR5: Output voltage regulation potentiometer LED1: Input power indicator, blue.
J7 default open circuit users can choose according to the actual practical requirements of the appropriate start mode J6: delay set jumper this jumper only for the load when the computer motherboard application, mode 0 J8: LED1-LED3 external lead-out terminal, other conditions are not set ie, need to be an external LED when the outlet leads.
1 pcs lot uninterruptible power supply computer access control security industrial dc power supply DC UPS power supply module - Led4: output voltage indicator, red, with output voltage when the output is off when off. J7 short circuit: j5 closed start power, turn off the power is turned off, when the power is turned on as long as J5 is automatically activated power. In the back-up power as a computer, the module can control the motherboard through J4 switch machine, when the battery is under pressure to send instructions to the motherboard shutdown.
This lamp flashes when the battery voltage drops below the start threshold voltage VSTART. When the input power is normal, led2: charge is completed after the lights, charging off LED3: charge this light, green, red, after the completion of charging off. When the battery voltage is lower than the undervoltage protection threshold voltage VUVP, the power supply can not be activated and the lamp flashes twice, indicating that the battery is undervoltage.
