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

Voltmeter with voltage protection for servo regulators

The RG-72K is a control relay designed for servomotor-driven voltage regulators, ensuring a stable and protected voltage output in electrical systems. This device simultaneously monitors the input (mains) voltage and the regulator's output voltage, providing precise and safe system control.
Thanks to its dual display, the device shows both input and output voltage in real time, facilitating continuous monitoring of the regulator's operation. It also incorporates automatic motor control functions to adjust the output voltage according to the configured values.
The RG-72K has multiple configurable parameters, such as desired output voltage, tolerances, protection times, and motor speed, allowing it to be adapted to different applications and working conditions.

Its most notable features include:

• Automatic control of regulators with servomotor
• Simultaneous display of input and output voltage
• Configurable overvoltage and undervoltage protection
• Switched relay output (NO/NC)
• Configurable audible alarm (buzzer)
• Control of protection and recovery times
• Motor speed and operating zone adjustment

The device has a measurement range of 1 to 300V AC (phase-to-neutral) with an accuracy of ±1% , ensuring reliable monitoring. It operates on a 220V AC (50/60 Hz) power supply and has low power consumption (<6VA).
Its compact 72 x 72 mm design allows for front panel mounting, facilitating integration into electrical panels. Furthermore, it incorporates motor control outputs ( 24V/2A AC ) and relay contacts ( 250V/5A AC ), making it a complete solution for voltage regulation systems.
The device operates by automatically controlling the regulator's motor to maintain the voltage within the set limits. If the voltage falls outside the configured range, the device activates the protective devices, switches the relay, and may sound an audible alarm.
As for maintenance, it only requires basic cleaning with a dry or slightly damp cloth, avoiding harsh chemicals. For safe installation, it is recommended to install an accessible switch or circuit breaker and follow the manufacturer's instructions.
The RG-72K is an advanced, precise, and configurable solution for voltage regulator control, ideal for industrial applications where stability, protection, and automation of the electrical system are required.
