With the increasing popularity of information technology (IT) applications in hospitals, uninterruptible power supplies (UPS) have also been widely used. Most UPSs are basically long-term online workers and therefore have a high failure rate. This article takes the most common faults of the on-line UPS of the Santak MP1000 as an example. The UPS repair method is described in detail from three aspects: the damage of the power fuse; the failure of the battery and the charger in the battery; the failure of the control circuit and the power drive circuit of the inverter.
