Modular voltage indicator, 3-phase, digital LDM-11 EXT10000316

3-Phase Voltage Indicator – Precise Network Status Monitoring

The LDM-11 voltage indicator is a reliable tool for monitoring voltage in three-phase networks. Thanks to its compact size – only one module wide – the device allows for quick and easy reading of the voltage value on each phase. It is particularly useful in installations cooperating with photovoltaic systems, where precise voltage control is crucial for proper operation and safety.

Compact design and wide application

The LDM-11 stands out not only for its small dimensions, making it easy to mount even in limited space, but also for its versatility. It will work both in home, industrial and agro-industrial installations. A wide range of voltage indications (80 ÷ 500 V AC) and high measurement accuracy (1%) guarantee reliable data necessary for analysis and optimization of network operation.

Advantages and benefits:

• Clear measurement: Three voltmeters provide simultaneous voltage reading for each phase, making it easier to quickly identify potential problems.
• Compact dimensions: The single-module housing minimizes the space occupied in the switchgear cabinet.
• Wide measurement range: The device operates in the range of 80-500V AC, making it a universal solution for different types of installations.
• High accuracy: Measurement accuracy at the level of 1% ensures reliable data necessary for correct diagnostics.
• Ideal for PV installations: Allows monitoring of voltage on the AC side in photovoltaic systems, which is important to ensure their safe and efficient operation.
• Easy installation: Mounting on a TH35 rail is simple and quick.

Applications:

The LDM-11 indicator finds application everywhere where continuous monitoring of voltage in three-phase networks is required:

• Electrical installations in residential and commercial buildings.
• Photovoltaic systems (on the AC side).
• Industrial and agro-industrial installations.
• Electrical switchboards.
• Service and diagnostics of electrical installations.

Construction and mounting:

The LDM-11 has been designed with ease of installation and use in mind. The device is mounted on a standard TH35 rail, which ensures stability and safety. The compact housing made of high-quality materials protects the internal components from mechanical damage and environmental conditions. Connection cables with a cross-section of 0.2 to 2.5 mm² provide a solid electrical connection. The device has a protection class of IP20, which means protection against touching with a finger and against the ingress of solid objects larger than 12.5 mm.
