Dual DC Power Switching Module Dual Low Voltage Differential Ideal Diode 15A UPS Uninterruptible Power Supply 1pcs
- Pin Description:1: Mains power input positive 2: Main power input negative (ground) 3: Standby power input negative (ground) 4: Standby power input positive 5: Output negative (ground) 6: Output positive Indicator light: D1: red light, bright when main power V1 is powered, extinguished when secondary power V2 is powered. D2: Green light, on when the secondary power supply V2 is powered, off when the main power supply V1 is powered. Potentiometer: VR1: main power switching voltage adjustment potentiometer. When the main power supply voltage is lower than the voltage set by VR1, the main power supply will be switched off immediately and the output will be switched to the backup power supply. Main power switching voltage VUVP for the test point TP1 voltage 5 times, according to the following formula:VUVP=VTP1×5 (V) For example, if the potentiometer VR1 is adjusted so that the TP1 voltage is 2V, then the switching voltage VUVP = 2 × 5 = 10 (V). When the main power supply V1 voltage is lower than 10V, it immediately cuts off the main power supply and at the same time switches to the standby power supply. The default shipping switching voltage is 10V. VR2: Main power supply recovery voltage VSTART adjustment potentiometer. When the main power supply voltage is higher than the voltage set by VR2, it immediately switches off the standby power supply and returns to the main power supply output. The main power supply recovery voltage VSTART is 5 times the voltage of the test point TP2,
