3-fázový elektromer ALLNET ALL3697-32A — 32 A, S0 impulzný výstup, induktívne meranie

The ALLNET ALL3697-32A is a 3-phase power meter designed to measure electrical energy in three-phase installations with a maximum current of 32 A. The meter uses induction-based measurement principles to provide reliable active energy monitoring and includes an S0 pulse output for connection to building management systems, energy loggers or data concentrators. Its compact form factor and DIN-rail compatible housing make it suitable for residential distribution boards and light commercial electrical panels where clear energy accounting is required.

Advantages

The induction measurement method provides stable active energy readings without the need for complex digital sensors, reducing susceptibility to certain types of electrical interference. The integrated S0 pulse output enables straightforward integration with external monitoring and automation equipment for pulse counting and cumulative energy recording. The device supports three-phase measurement in a single compact module, simplifying installation in standard electrical cabinets and reducing the number of separate meters required for multi-phase circuits.

Suitable for

• Residential distribution boards for whole-house or per-circuit energy monitoring
• Light commercial premises such as small offices, shops and cafés
• Integration with building management systems and energy loggers using S0 pulse input
• Applications that require compact three-phase measurement up to 32 A

Key specifications

• Measurement type: three-phase active energy (induction measurement)
• Maximum continuous current: 32 A per phase
• Pulse output: S0 pulse interface for energy pulses
• Mounting: DIN-rail compatible housing for electrical cabinets
• Display: integrated mechanical or electronic energy counter (shown on front)
• Connection: screw terminals for phase and neutral conductors

How to use

Install the meter on a DIN rail inside the electrical panel and connect the three phase conductors and neutral according to the wiring diagram provided by the manufacturer. Ensure that the nominal current does not exceed 32 A per phase and that the meter is supplied from the appropriate voltage system. Configure the external monitoring device to accept S0 pulses if cumulative energy recording is required; the S0 output emits standardized pulses corresponding to measured energy so a compatible pulse counter or energy logger can translate them into kWh values. Follow local electrical codes and disconnect power before wiring.

Recommendations

For accurate long-term readings, install the meter in a dry, ventilated electrical cabinet away from direct heat sources and strong electromagnetic interference. Verify pulse rate and wiring polarity when integrating with building automation to ensure correct cumulative energy accounting.
