In modern IT and industrial environments, reliable voltage monitoring plays a central role. The Power Detector 110–230V from HW-group has been designed to ensure precise detection and control of mains voltage. This compact measurement device detects in real time whether a supply voltage in the range of 110 to 230 volts AC is present. As soon as a voltage drop or interruption is detected, the sensor responds immediately and triggers a notification or alarm via its galvanically isolated relay output. This makes the voltage detector a key component for anyone who depends on continuous power availability.

The Power Detector 110–230V is particularly used where every second counts—such as in server rooms, data centers, system cabinets, or production environments. Its reliability helps prevent downtime and protects sensitive systems from disruptions in good time. In combination with monitoring systems such as Poseidon2, Damocles2, HWg-STE2, or Ares, it offers a versatile solution for real-time mains voltage monitoring in critical applications. IT administrators, technicians, and facility managers use the Power Detector to keep an eye on the status of their power supply at all times.

With its compact, pluggable design, the HW-group Power Detector can be installed quickly. It is simply plugged into a socket and connected to a monitoring system with a digital input via a two-wire cable. The galvanicallyisolated relay output is electrically separated to protect the connected device from potential network disturbances or overvoltage. Thanks to the international plug sets (EU, UK, US), it can be used globally and adapted flexibly. The thoughtful design makes it an indispensable component of modern energy monitoring systems.

In addition to monitoring individual sockets or circuits, the Power Detector 110–230V allows integration into comprehensive monitoring networks. It can work together with other sensors for temperature, humidity, or smoke detection. When connected to the HWg-PDMS software, all measured data can be recorded, visualized, and exported for detailed analysis. This way, operators gain valuable insights into the stability of their infrastructure and can act preventively before damage occurs.

Key Features and Technical Advantages

The Power Detector 110–230V impresses with its well-balanced combination of precision, safety, and universal compatibility. The main purpose of this sensor is to clearly detect the presence or absence of mains voltage. As soon as no voltage is detected, the potential-free relay contact opens and can trigger alarms, send status messages, or activate emergency shutdowns through connected systems. This direct response capability significantly reduces risks for data- or production-critical systems.

Fields of Application and Use Cases

The possible applications of the HW-group Power Detector 110–230V are diverse. In server rooms, power failures can have serious consequences—from data loss to production downtime. The detector sends an immediate feedback to the central monitoring system when a power failure occurs, which can then trigger alarms via e-mail, SMS, or SNMP traps. This ensures responsible personnel are informed instantly and can take action before downtime is prolonged.

In industrial manufacturing plants, the power failure detector safeguards the continuous power supply of sensitive machines. A voltage loss caused by cable damage or switching errors can thus be detected immediately. In telecommunications, voltage monitoring protects critical network components from sudden outages. Operators can maintain system stability and at the same time document energy data to analyze power supply trends. Moreover, the Power Detector can also be part of comprehensive safety solutions where parameters such as voltage, temperature, water leaks, or vibrations are monitored together.

Integration into Existing Monitoring Systems

A key advantage of the Power Detector 110–230V is its full compatibility with other HW-group products. Via digital inputs, the device can be seamlessly integrated into systems such as Poseidon2, Damocles2, or HWg-STE2. In combination with HWg-Ares LTE units, the Power Detector can also be deployed for mobile or remote sites. In such cases, the system reports power loss wirelessly via GSM or LTE to defined recipients, making it ideal for outdoor stations and remote technical facilities.

The HWg-PDMS software offers convenient evaluation of all recorded data. It enables the display of trend curves, export to Excel, and automatic report generation. Combined with other sensors such as temperature or humidity probes, a modular energy monitoring system is created, providing full control over the physical parameters of a facility. Thanks to open interfaces, third-party systems can also be integrated—a key benefit for operators seeking a flexible and expandable solution.

Simple Installation and Setup

System setup requires no special technical training. The Power Detector simply plugs into a wall socket. The included two-wire cable connects the relay output to a digital input of the monitoring device. When voltage is detected, the relay output remains closed. If the voltage fails, the contact opens and triggers an alarm. Due to galvanic isolation, the connected system is electrically insulated—an essential safety feature for stable monitoring networks.

For applications in different countries, the included international plug set ensures that the Power Detector can be used worldwide. This is a decisive advantage for multinational data centers or globally active industrial companies.

Robustness and Reliability in Continuous Operation

The Power Detector was designed for demanding environments. Data centers often experience high ambient temperatures, and continuous 24/7 operation is the norm. The device is rated for temperature ranges from -30 °C to +60 °C and operates reliably at up to 100% relative humidity. The robust housing protects the electronics against dust and moisture and ensures a long service life, even under constant load. This reliability significantly reduces maintenance efforts and operating costs.

Advanced Functions for Energy Monitoring

In modern infrastructure systems, the importance of energy monitoring is continuously increasing. The HW-group Power Detector 110–230V is not only a precise sensor but also a building block for creating smart monitoring systems. When combined with temperature probes, humidity sensors, or power meters, it enables the development of a complete energy management system. Preventive maintenance is also supported: for instance, if recurring voltage drops are detected through trend analysis, root causes can be identified and eliminated early.

Typical Practical Applications

• Monitoring of supply sockets for servers, UPS systems, and network cabinets.
• Mains voltage supervision for production machinery on assembly lines.
• Detection of power failures in electrical distribution panels and switchboards.
• Combination with temperature and humidity sensors for comprehensive infrastructure monitoring.
