The compact backup power supply for 12 V devices with power failure notification
The HW group UPS 12V is a backup power source for devices with 12 V DC supply. It delivers a stable output voltage of 12 V at up to 1.5 A and reports a failure of the external power supply via an integrated relay output. In terms of power supply, the UPS 12V is compatible with all HW group devices that are operated with 12 V power adapters.
In the IT sector, industry and households, an uninterruptible power supply is standard. For small devices such as monitoring systems, telephone systems (PBX) or controllers with a 12 V power adapter, however, there are hardly any suitable solutions, and a complex 230 V UPS is uneconomical for this purpose. This is where the UPS 12V comes in: it protects your device without significantly increasing the installation requirements.
Reliably protect small devices
The UPS 12V bridges power failures with a built-in battery and provides a timely signal to the connected device.
Built-in battery
The 1.3 Ah battery automatically takes over the supply of the connected device in the event of a mains failure.
Stable 12 V up to 1.5 A
Stable output voltage of 12 V with a load of up to 1.5 A.
Relay output
Failure of the external power supply is reported via a signal relay (50 V / 1 A).
Connection via pin connector
The device to be protected is simply connected to the pin connector (Power Out).
Same power adapter as the end device
The UPS is operated with a standard 12 V / 1.5 A power adapter, as is often already available for the end device.
Also with 5 V output
The UPS 12V and 5V variant additionally supplies devices with 5 V and reports its status via 1-Wire UNI.
Clear LED indicators
The green Power IN and Power OUT LEDs indicate mains and output status.

How the UPS 12V is designed
The UPS 12V is housed in a compact plastic enclosure (135 x 60 x 90 mm, 750 g). Connections, main switch and LEDs are easily accessible on the housing. The equipment differs depending on the version.
Barrel connector for the power adapter (Power IN)
External connection for the power adapter with 12 V, at least 1.5 A. The manufacturer specifies a barrel connector with 2.1 mm inner and 5.5 mm outer diameter.
Main switch
The red switch disconnects the battery. It may only be switched on during operation. If the UPS is not in use, switch the main switch off.
LED indicators
Power OUT lights up when the UPS output is switched on. Power IN lights up when the external power supply is connected. On the UPS 12V and 5V version, Overload (overload of the 12 V or 5 V branch) and Battery Fail (flashes in the event of battery failure) also indicate the status.
Pin connector Power Out
The device to be protected is connected here. On the UPS 12V it is a dual pin connector with 12 V. On the UPS 12V and 5V it is a triple pin connector (+5 V, GND, +12 V) with common ground potential (GND).
Pin connector of the signal relay (UPS 12V)
Triple pin with the connections NO (normally open), COM (common contact) and NC (normally closed). An outer pin is always connected to the middle pin (COM). The contact is rated for 50 V / 1 A.
1-Wire UNI output (UPS 12V and 5V)
Connection for linking to a Poseidon2 or Ares 10. The status of the UPS is transmitted via this.
Reset/Start (UPS 12V and 5V)
Restores the power supply after an overload.
Battery
Built-in battery with 1.3 Ah. The UPS 12V and 5V additionally contains an internal 5 V converter for the 5 V output.
From mains operation to battery operation
The UPS is supplied by the same 12 V power adapter that also powers the end device. In the event of a failure, the battery takes over.
- In normal operation, the power adapter supplies the UPS and thus the connected device; the battery is charged
- If the external power supply fails, the 12 V battery immediately takes over the supply
- The Power IN LED goes out, the Power OUT LED remains lit
- On the UPS 12V the signal relay opens at the same time (NO opens, NC closes)
- The supplied device can report the failure or correctly terminate its activity
- After the power supply returns, the relay closes again and the battery is charged
- On the UPS 12V and 5V the 1-Wire UNI output reports battery voltage, battery current, the estimated operating time at the current load and the status of mains or battery operation
- Each of these values occupies a sensor position in the connected device. Values that are not required can be disabled via the “1-Wire UNI USB Calibrator”
Connection and functional check
Commissioning is carried out in a few steps.
- Connect the 12 V / 1.5 A power adapter to the UPS. Both green LEDs light up
- Connect the device to be protected to the Power Out pin connector
- Optional: Connect the relay output (UPS 12V) or 1-Wire UNI output (UPS 12V and 5V) to the monitoring device
- Switch on the UPS at the main switch
- For a functional check, unplug the power adapter: the Power IN LED goes out, the Power OUT LED remains on
- If the UPS is switched off at the main switch, the Power OUT LED also goes out

Frequently asked questions
What is the UPS 12V and what is it used for?
The UPS 12V is a backup power source for devices with 12 V DC supply. It delivers 12 V at up to 1.5 A, bridges power failures with its battery and reports the failure of the external supply via a relay output. Typical applications are monitoring systems, telephone systems and controllers.
Are there options or variants?
Yes, four: UPS 12V, UPS 12V Set (with power adapter), UPS 12V and 5V (additional 5 V output) and UPS 12V and 5V Set (with power adapter). Selection is made above the shopping cart button.
Is a power adapter included in the scope of delivery?
Only with the set versions. The basic versions UPS 12V and UPS 12V and 5V are supplied without a power adapter, as the UPS is operated with a standard 12 V / 1.5 A power adapter that is often already available for the end device.
Which power adapter is required?
A power adapter with 12 V and at least 1.5 A. Connection is via a barrel connector (inner 2.1 mm, outer 5.5 mm). The manufacturer offers, among others, the “12V/1.5A Wall plug adaptor INT” with three interchangeable plugs (EUR, UK, US).
What does the relay output mean?
On the UPS 12V a signal relay (50 V / 1 A) signals the power failure. NO is open in the idle state, i.e. when the power supply is disconnected, and closes when the device is supplied from the external power adapter during operation. NC closes in the event of a failure of the external supply. In this way the connected device can report the failure or safely terminate its activity.
What is the difference between UPS 12V and UPS 12V and 5V?
The UPS 12V and 5V additionally has a 5 V output (12 V / 1.5 A and 5 V / 0.5 A, usable simultaneously) with an internal 5 V converter. Instead of the signal relay it offers a 1-Wire UNI output with status values and additionally the Overload and Battery Fail LEDs as well as the Reset/Start button. The UPS 12V delivers 12 V up to 1.5 A and reports via the relay.
Which status values does the 1-Wire UNI output provide?
On the UPS 12V and 5V: battery voltage, battery current, estimated operating time at the current load and mains or battery operation. Each value occupies a sensor position in the connected device (e.g. Poseidon2 or Ares 10). Values that are not required can be disabled via the “1-Wire UNI USB Calibrator”.
How do I check the function?
Connect the power adapter, switch on the UPS and then unplug the power adapter. The Power IN LED goes out, the Power OUT LED remains on. When the UPS is switched off, Power OUT also goes out.
What do the LEDs mean?
Power OUT: output switched on. Power IN: external power supply connected. Overload (UPS 12V and 5V): overload of the 12 V or 5 V branch. Battery Fail (UPS 12V and 5V): flashes in the event of battery failure. After an overload the Reset/Start button restores the power supply.
Is the status of the main switch indicated?
No. The status of the main switch is not indicated and must be checked by the switch position. The main switch disconnects the battery and should only be switched on during operation.
What is the battery capacity?
1.3 Ah at 25 °C. The capacity depends on the temperature: 85 % at 0 °C, 100 % at 25 °C and 102 % at 40 °C.
What load can the UPS supply?
The UPS 12V delivers up to 1.5 A at the 12 V output. The UPS 12V and 5V delivers 12 V / 1.5 A plus 5 V / 0.5 A; both outputs can be used simultaneously.
Which devices is the UPS 12V compatible with?
With all HW group devices that are operated with 12 V power adapters, e.g. Poseidon2, Damocles2, Ares 12, Perseus and IP WatchDog2.
