Santak UPS power supply no output, what's the matter? |

Santak UPS power supply no output, what's the reason for this?:
1, check the battery power supply lines, especially current limiting resistors
2 、 check whether there are electrical components such as burning, measuring and changing
3. Measure the AC output tube and compare the measurements to see if it is damaged
4. Measure the voltage of each pin of the control module and compare the voltage of the block to analyze the voltage
5, use a magnifying glass to see printed circuit board surface, check whether there is.
6 、 prepare circuit diagram, analyze and repair according to the system
Santak UPS power output without voltage troubleshooting. Santak UPS power, AC and DC boot panel display is normal, there is no indication of failure, this UPS plug in the power on the normal, there is output; but after the city power failure, the battery shows the normal state of operation, but no voltage output.
(1) UPS electric power plug (normal) boot boot - panel display: AC bypass (bypass relay action) - panel display lights (no prompt bypass relay action; note: the normal relay will be action!); the output voltage, but can not be regulated, is estimated to bypass the direct output of the City (but the electric panel bypass indicator is off, the normal display output).
(2) Santak UPS power supply plug city (normal battery): normal boot DC panel display, when the output indicator lights up, the relay has no action, no voltage output (normal to relay action, instant normal output voltage!)
Uninterrupted power supply to check the main board of the relay, the relay is removed, you can first measure the coil is burned, if not burned, it may be sticky contact, you can relay the power test, determine the failure to replace
