380V 415V 440V 3 Phase Voltage Stabilizer

The Industrial Voltage Stabilizer is always monitoring the three-phase supply and making a comparison with what it should be putting out. If the voltage strays, the control system kicks in and tells the stabilizer to add a bit of corrective voltage to get things back on track.

This correction has the output slowly heading back towards the specified 380V, 415V, or 440V. Depending on what’s needed, this regulation can apply to all three phases or each one can be controlled independently. Independent phase regulation is often the way to go if the supply coming in or the loads are not balanced.

• CNC machining:Provides controlled three-phase voltage to the spindle drives, servo systems, controllers, and auxiliary devices that are working together in changing workshop load conditions.
• Injection moulding:Supports the three-phase motors, heaters, pumps, and control components that work together in long and repetitive production cycles.
• Packaging and printing:Helps to maintain the right voltage for motors, sensors, heating systems, PLCs, and electronic control cabinets that work together in coordinated fashion.
• Pumps and compressors:Supports industrial motor loads where starting current and feeder voltage drops need to be considered during stabilizer sizing.
• Automated production lines:Provides centralised voltage regulation for robots, conveyors, inspection equipment, processing machinery, and associated control systems.

First and foremost, you need to confirm the minimum and maximum incoming voltage on all three phases during different production periods. A nominal supply value does not give you the full picture of what you need.

Provide JINMA ELECTRIC with all the necessary information including:

• Total operating load in kVA or maximum current
• Motor starting current and starting method
• Balanced or unbalanced load conditions
• Required output voltage and tolerance
• Three-wire or four-wire connection
• Frequency and neutral requirements
• Indoor or outdoor installation conditions
• Bypass, isolation, communication, and protection requirements

In a nutshell, a standard stabilizer is usually manufactured for one specific nominal output. To get a stabilizer that can output multiple voltages you need a custom engineered configuration.

The answer is quite simple – you use the voltage stated on the connected equipment nameplate. Verify that it matches the motor, control transformer, drives, heaters, and auxiliary circuits.

Yes it can, but you do need to select an independent phase-regulation design. Get the voltage measurements for each phase so we can evaluate the right topology.

Don’t just use the running power of the motors – take into account the combined maximum load, power factor, simultaneous operation, and starting current. Motors and compressors need to be properly sized.

Nope. The output frequency follows the incoming supply. If you need to change frequency, you’ll need to add a frequency converter.
