UPS 12V Series – Reliable Backup Power Solutions for 12 V and 5 V Devices

The HW group UPS 12V Series is the ideal solution for uninterrupted power supply to devices operating on 12 V or 5 V DC. These compact backup systems are specifically designed for critical IT, industrial, and IoT environments, helping to prevent downtime and maintain continuous operation. With high energy efficiency, robust construction, and full compatibility with all HW group devices, the series guarantees maximum reliability.

Four Variants for Different Requirements

The series includes four models tailored to various application scenarios:

UPS 12V

The base unit of the series is equipped with a 12 V / 1.3 Ah battery and a relay output for power‑failure signaling. A separate 12 V / 1.5 A adapter is required, though it is often already provided by the connected device. Ideal for compact systems with direct DC power input.

UPS 12V Set

A pre‑configured kit including the UPS unit, 12 V / 1.5 A adapter, relay output, and connection cables. This plug‑and‑play solution is ideal for server rooms, surveillance systems, and small control panels.

UPS 12V and 5V

Adds a 5 V output for dual voltage operation. This enables simultaneous power supply to both 12 V and 5 V devices, such as network hardware and sensor controllers. It uses separate 12 V / 1.3 Ah and 5 V / 3.1 Ah batteries for independent power stability.

UPS 12V and 5V Set

The all‑in‑one package features dual‑voltage outputs, an AC adapter, and matching terminal connectors. Perfect for complex building automation, IoT, and industrial applications.

Technical Features of the HW group UPS 12V Series

• Output voltage: 12 V up to 1.5 A; dual models include an additional 5 V output
• Input voltage: 12 V / 1.5 A via standard power supply
• Battery: 12 V / 1.3 Ah with temperature compensation (Capacity: 85 % at 0 °C, 102 % at 40 °C)
• Compact form factor: 135 × 90 × 60 mm / 750 g
• Operating temperature: –20 °C to +60 °C
• Relay output: 50 V / 1 A signal for power‑failure detection
• Connectors: Pin plug (12 V) or dual terminal blocks (12 V / 5 V models)

Operation and Handling

The UPS 12V Series automatically and seamlessly switches to battery operation in the event of a mains power failure. The internal circuit ensures a smooth changeover so that connected devices continue operating without interruption.

1. Connect the power adapter to the UPS unit – the “Power IN” and “Power OUT” LEDs will light green.
2. Connect the device to be protected via the pin plug or terminal block.
3. During a power failure, “Power IN” turns off while “Power OUT” remains lit – the battery is active.
4. The built‑in relay reports the power failure to the connected system (e.g., Poseidon2 or Ares 12) for immediate response.

Ideal for IT, Industrial, and Smart Home Environments

• Server‑room monitoring – backup for sensors, cameras, and monitoring units against power loss
• Industrial control – maintains power supply for PLCs and production sensors
• Networking equipment – protection for routers, switches, access points, and gateways
• Smart Home – backup for security cameras and alarm controllers
• Telecommunications – keeps PBX systems and IoT hubs online during outages

Relay Output for Power‑Failure Notification

All UPS models include a relay output that automatically reports power failures. Combined with HW group devices like Poseidon2 or Ares 12, the signal can trigger emails, SMS, or SNMP traps to administrators, ensuring real‑time alerts and quick action.

Advantages of the HW group UPS 12V Series

• Compact and efficient DC UPS design with low power consumption
• Universal for 12 V and 5 V devices – ideal for IT and IoT networks
• Durable and robust – wide temperature range and industrial housing
• Secure power‑failure notification through relay signaling
• Plug‑and‑play installation with clear LED indicators
• Cost‑effective alternative to conventional 230 V UPS systems

Benefits over Conventional 230 V UPS Systems

Traditional 230 V UPS units are often oversized for applications where only a few 12 V or 5 V devices require protection. The HW group UPS 12V Series provides a smart solution:

• No energy loss caused by AC/DC conversion
• Direct integration with 12 V and 5 V systems
• Silent operation – no fans or active cooling
• Instant switch‑over (< 5 ms) to battery power
• Built‑in relay for preventive maintenance alerts
