Datasheet, MOQ, lead time and quotation on request.
Capacity class: approximately 200-300 KVA (rated 300KVA). Common search sizes: 200KVA / 250KVA / 300KVA.
Product Overview
The 300KVA/240KW Compensated Regulator for Large Motors is an approximately 200-300 KVA (rated 300KVA) designed for this application. Key ratings: Power Rating (KVA): 300KVA / 240KW; Control Method: AC contactor type. Buyers searching a 200kva/250kva/300kva unit in this class get the same build with /240kw compensated regulator engineering.
Brief description
High power compensated regulator This is a high-power compensated voltage stabilizer designed for factories, workshops and other places that require stable voltage. It can automatically detect voltage fluctuations and quickly adjust through compensation technology to ensure that the voltage is always stable within a safe range, protecting large motors, CNC equipment and other valuable industrial equipment from voltage instability. It is particularly suitable for use in industrial areas with large voltage fluctuations.
Features
1. High power compensated regulator Self-healing superpower: automatically repair minor faults, no need to call the repairman all the time.
2. Winter and summer all-rounder: -30℃ to 60℃ all-weather operation.
3. Voltage recorder: automatically record 72 hours of electricity consumption “black history”.
4. Balancing master: automatic three-phase current allocation, no “partiality”.

2. Artificial sun: protect nuclear fusion devices and make plasma control more precise.
3. Smart grid: act as “voltage balancers” for regional power grids and automatically reduce peaks and fill valleys.
4. Satellite manufacturing: protect the spacecraft test environment and simulate voltage conditions in space.
Product details

Moisture-proof coating: The circuit board can work normally even in 84 disinfectant

Silent Ninja: The noise is 3 decibels lower than the refrigerator compressor when running

Energy-saving expert: Standby power consumption is less than 5W, which is more energy-saving than mobile phone charger
FAQ
Q: What is the maximum voltage fluctuation that can be tolerated?
A: When the input fluctuates by ±35%, the output can still be stabilized at ±1%
Q: How loud is the alarm?
A: 85 decibels, equivalent to an alarm clock, and an optional flash alarm
Q: Do I need to dismantle the entire machine for maintenance?
A: The main components can be pulled out separately like drawers‌
