Three-phase 10.5 -300 KVA

FULLY AUTOMATIC PROTECTED THREE-PHASE SERVO VOLTAGE REGULATOR WITH MICROPROCESSOR

Redsan three-phase servo regulators are automatic regulators that regulate your mains voltage with variac motor and microprocessor control card. Provides safe and stable output voltage where your mains voltage is unstable and unreliable. It is manufactured with the capacity to operate smoothly even at full load and when the voltage changes. It shows the input voltage and output voltage on the digital displays separately for each phase, at the same time, this display is the control card, so when there is a problem, it provides the possibility to easily correct the adjustment problem on the card.

Microprocessor-Controlled Fully Automatic Protected Three-Phase Servo Voltage Regulator

The microprocessor-controlled, fully automatic, protected three-phase servo voltage regulator is a professional energy stabilisation system that instantly analyses unstable and fluctuating voltage from the mains supply to provide a constant, safe and balanced output voltage. Developed specifically for industrial facilities, production lines, and high-power three-phase devices, this model offers precise regulation performance thanks to its variable motor technology and microprocessor-controlled structure.

Sudden surges, drops and phase imbalances in the mains voltage can cause serious malfunctions in sensitive equipment such as CNC machines, automation systems and medical devices. A three-phase servo voltage regulator eliminates these risks, ensuring the safe and uninterrupted operation of systems.

Working Principle

Device, each phase separate separate monitored microprocessor controlled control card with operates. Mains voltage is continuously measured and variac motor system via automatically as corrected. There is a separate digital screen for each phase. These screens both input and output voltage display and also control panel as function performs. Thus the user system parameters easily monitor and when necessary adjust.

Technical Specifications

• Fully automatic servo-controlled system
• Microprocessor-controlled protection circuit
• 3 digital voltmeters (phase-based display)
• Correction speed: 200 VAC/second
• Output voltage tolerance: 2%
• Device efficiency: 97%
• 3-second operating endurance at 150% capacity
• Operating temperature range: -10°C to +55°C

Input and Output Values

The input voltage range is 160–250 VAC or 180–260 VAC between phase and neutral; and 275–430 VAC or 310–450 VAC between phases. The output voltage is 220 VAC between phase and neutral, and 380 VAC between phases, and can be set to 230 VAC or 400 VAC.

Advanced Protection Systems

• Overvoltage protection unit
• 7-second delay protection circuit (adjustable)
• Automatic cut-off against sudden voltage fluctuations
• 1-0-2 mechanical bypass switch (Mains / Regulator selection)
• Adjustable sensitivity tolerance from the front panel

The protection unit activates to prevent damage caused by sudden voltage fluctuations. When the voltage returns to normal levels, the system automatically resumes operation. This feature is particularly critical for equipment safety in production lines.

Durable Mechanical Structure

The glass fibre wire transformer winding is resistant to temperatures up to 250°C. Designed with heavy industrial production quality, the body structure offers long-lasting use. Thanks to its high adjustment speed, it responds quickly to voltage changes and does not create fluctuations in the output.

Areas of Use

Three-phase servo voltage regulator; can be safely used in CNC machines, automation systems, injection moulding machines, printing presses, textile machinery, medical devices, laboratory equipment, laser systems, lifts, air conditioning systems, UPS systems, server rooms and telecommunications infrastructure.

It also provides effective solutions in all areas requiring marine equipment, card access systems, fire safety systems, heating and cooling systems, and three-phase power stabilisation in production facilities.
