The UPS 12V is a compact backup power supply for devices requiring 12 V DC. It provides a regulated 12 V output up to 1.5 A and includes a built-in relay output to signal external power loss. The unit is compatible with all HW group devices powered by 12 V adapters. Use Case While UPS systems are common in IT and household environments, small 12 V-powered devices (e.g., PBXs, monitoring units, control systems) are typically backed up using inefficient 230 V UPS solutions. The UPS 12V offers a dedicated, low-power alternative with minimal installation overhead. During a power outage, the internal battery supplies 12 V to the load and opens the signal relay to indicate power loss. Once power is restored, the relay closes and the battery recharges. Connection and Operation Connect the power adapter to the UPS. Both green LEDs should turn on. Connect the device to the Power Out connector. Switch on the UPS. Function Test Disconnect the power adapter. Power IN LED turns off. Power OUT LED remains on. Switch off the UPS. Power OUT LED turns off. Note: The UPS power switch has no status indicator. Verify its state by checking the physical switch position.
