UPS 12V Series: Reliable Backup Power Supply for 12V/5V Devices

The UPS 12V Series from HW-group offers versatile and reliable backup power solutions for devices with 12V DC power supply.

This series includes four variants: UPS 12V, UPS 12V Set, UPS 12V and 5V, and UPS 12V and 5V Set.

Each variant is designed to ensure uninterrupted power supply for critical applications in IT, industry, and private households. With a stable output voltage of up to 12V at 1.5A and an integrated relay output function for signaling power failures, these devices offer an efficient alternative to conventional 230V UPS systems, which are often oversized and inefficient for smaller devices.

The UPS 12V Series is compatible with all HW-group devices operated with 12V power supplies and is ideal for applications such as server monitoring, control systems, or PBX systems.

Package Contents of the Four Variants

Each version of the UPS 12V Series has been specially developed for different requirements, with the package contents tailored to the respective application:

• UPS 12V: This basic version includes the UPS unit with a 12V/1.3Ah battery, a pin connector for connecting the device to be secured, and an integrated relay output function for signaling power failures. A power supply is not included, as the UPS is operated with a standard 12V/1.5A power supply, which is often already available for the end device.
• UPS 12V Set: This set includes the UPS 12V unit as well as a suitable 12V/1.5A power supply, making installation easier. It also contains the pin connector and relay output function. This set is ideal for users who need a complete solution without additional components.
• UPS 12V and 5V: This variant extends functionality with an additional 5V output, which can be operated simultaneously with the 12V output. It includes the UPS unit with a 12V/1.3Ah or 5V/3.1Ah battery, dual terminal connectors for both voltages, and the relay output function. A power supply is not included.
• UPS 12V and 5V Set: This complete set includes the UPS unit with 12V and 5V outputs, a 12V/1.5A power supply, as well as dual terminal connectors. It is ideal for applications that need to secure both 12V and 5V devices simultaneously, such as combined network and control systems.

Technical Features of the UPS 12V Series

The UPS 12V Series is characterized by its robust construction and user-friendly operation. Here are the key technical specifications:

• Connection: The devices to be protected are connected via a pin connector (UPS 12V, UPS 12V Set) or dual terminal connectors (UPS 12V and 5V, UPS 12V and 5V Set), enabling easy integration.
• Output Voltage: 12V at up to 1.5A (all models), plus 5V for the UPS 12V and 5V and UPS 12V and 5V Set models.
• Input Voltage: 12V/1.5A via a standard power supply.
• Battery Capacity: 1.3Ah at 25°C (12V), with a capacity of 85% at 0°C and 102% at 40°C; for the 5V models, additionally 3.1Ah for 5V.
• Dimensions: 135 x 90 x 60 mm, compact for space-saving installations.
• Weight: 750 g, lightweight and easy to mount.
• Operating Temperature Range: -20°C to +60°C, suitable for demanding environments such as server rooms or industrial facilities.
• Relay Output: Signal relay with a load capacity of 50V/1A for reporting power failures.

Applications and Use Cases

The UPS 12V Series is ideal for applications where reliable power supply for smaller devices is required. While conventional 230V UPS systems are suitable for large installations such as data centers or hospitals, they are often inefficient for devices with 12V or 5V DC power supply.

The HW-group UPS 12V Series fills this gap by providing a compact and cost-effective solution for securing control systems, monitoring devices, PBX systems, or IoT devices. Examples of application areas include:

• Server Room Monitoring: Securing sensors and monitoring devices that monitor temperature, humidity, or energy consumption.
• Industrial Control Systems: Ensuring operational continuity of controllers in production facilities.
• Network Devices: Protecting routers, switches, or PBX systems from power outages.
• Household Applications: Securing smart home devices or security cameras operated with 12V or 5V.

The integrated relay output function allows power failures to be signaled to the connected device, so users are promptly informed of problems or the device can safely terminate its activities. This is especially useful in scenarios where data loss or operational interruptions must be avoided.

Functionality and Installation

Installing the UPS 12V Series is extremely simple. The connection is made in a few steps:

1. Connect the 12V/1.5A power supply to the UPS. Both green LEDs (Power IN and Power OUT) light up, indicating a successful connection.
2. Connect the device to be protected to the power-out pin connector (for UPS 12V and UPS 12V Set) or the dual terminal connectors (for UPS 12V and 5V and UPS 12V and 5V Set).
3. Switch on the UPS. To check the function, disconnect the power supply. The Power IN LED goes out, while the Power OUT LED remains lit, indicating that the battery is taking over the power supply.
4. In the event of a power failure, the signal relay opens, and the connected device can report the failure or safely terminate its activities. Once power is restored, the relay closes and the internal battery is automatically recharged.

Important note: The status of the main switch of the UPS is not indicated by LEDs and must be checked visually. This ensures that users can manually control the UPS when necessary.

Advantages of the UPS 12V Series

The HW-group UPS 12V Series offers numerous advantages:

• Efficiency: Compared to 230V UPS systems, the HW-group UPS is compact and energy-efficient, ideal for smaller devices.
• Flexibility: Support for 12V and 5V outputs (on the respective models) enables operation of various device types.
• Reliability: The robust construction and wide operating temperature range make the UPS suitable for demanding environments.
• User-Friendliness: Simple installation and clear status indication via LEDs make operation easy.
• Cost-Efficiency: By using standard 12V power supplies and avoiding unnecessary 230V systems, a cost-effective solution is provided.

The UPS 12V Series from HW-group is a powerful and flexible solution for uninterruptible power supply of 12V and 5V devices.
