Digital voltmeter (servo and current control for regulators) 72x72 mm (1-300 V AC)

Digital voltmeter (servo and current control for regulators)

The RG-72AK is an advanced control relay for servomotor-driven voltage regulators, designed to ensure precise, stable, and safe voltage regulation in electrical installations. This device allows for real-time monitoring and control of key system parameters, providing a complete solution for industrial applications.

The device stands out for its triple simultaneous display , showing on screen:

• Regulator output voltage
• Input voltage (mains)
• Output current

This functionality allows for complete system control on a single device, facilitating diagnosis and decision-making.
The RG-72AK automatically controls the regulator's servomotor to maintain the output voltage at the set value. It also incorporates both voltage and current protection, significantly improving system safety.

Main features:

• Automatic control of regulators with servomotor
• Simultaneous display of input voltage, output voltage, and current
• Precise regulation of configurable output voltage
• Overvoltage, undervoltage and overcurrent protection
• Switched relay output (NO/NC)
• Configurable audible alarm (buzzer)
• Control of protection and recovery times
• Motor speed adjustment (slow and fast movement)

The device allows for extensive menu-based configuration, including parameters such as target voltage, tolerance, protection limits, actuation times, and number of automatic retries, adapting to different installation needs.
In terms of technical features, it offers:

• Voltage measurement range: 3 – 300V AC
• Current measurement range: 1 – 250A (with transformer)
• Accuracy: ±1%
• Power supply: 85 – 240V AC / 50-60 Hz
• Relay output: 250V / 5A AC
• Motor output: 24V / 2A AC
• Power consumption: <6VA

Its compact 72 x 72 mm form factor allows for front panel mounting, facilitating integration into electrical panels. Furthermore, its robust design enables operation under demanding conditions, with a working temperature range of -20°C to +55°C .
The system operates completely automatically: it continuously monitors voltage and current, adjusting the regulator to maintain values within set limits. In case of malfunctions, it activates the protective devices, switches the relay, and emits an audible signal if enabled.
The RG-72AK is a professional, precise and highly configurable solution for voltage regulator control, ideal for applications where maximum stability, protection and control of the electrical system are required.
