A variable frequency power supply is a power conversion equipment that takes the incoming AC power at whichever voltage and frequency the local grid produces and presents a regulated output to the load at the voltage, frequency and current drawn by the equipment attached. The Jinma is set for 190V input and 380V output so is suitable where the supply voltage is lower than the normal modern requirement for three phase equipment.
Three features define the product:
| Parameter | Specification |
| Product type | Variable frequency power supply (frequency converter) |
| Input voltage | 190V |
| Output voltage | 380V |
| Output frequency | 50Hz / 60Hz (dual-frequency control) |
| Core material | Nanocrystalline iron core |
| No-load loss | Approximately 30%–50% lower than conventional cores (manufacturer data) |
| Voltage regulation | Real-time monitoring with intelligent control algorithm |
Frequency mismatch is one of the most overlooked causes of equipment failure in international trade. Most of Europe, China, and much of Asia operate on 50Hz systems, while North America and large parts of Central America use 60Hz. Belize is an unusual case because both standards are present within its grid.
For importers and end users, that creates a real headache. Electrical machines are designed for a specific frequency. Running 50Hz-rated equipment on a 60Hz supply — or the reverse — can change motor speed, increase heating, and shorten service life. A dual-frequency power supply removes the guesswork: it accepts the local frequency and delivers the 380V output the equipment needs, regardless of which system the supply comes from. For buyers in markets with mixed standards, one unit type can serve multiple sites, which also simplifies spares and inventory.
Background. Economy A Central American nation, Belize relies on tourism and agriculture. The increase of both increases the demand for stable, quality power – and for protective solutions that defend sensitive loads from irregular supply.
The problem. In some areas of Belize, the grid is not fully built. The voltage and frequency are inconsistent in different regions of the country, and imported equipment is at risk of being operated at a supply for which it was not designed. The outcome could be production loss, damage to equipment and energy loss.
The solution. Jinma has designed a 190V to 380V variable frequency power supply for the Belize market. The ability to use dual-frequency control, allowing the unit to run on 50Hz and 60Hz mains while still providing 380V, will be critical for this market. The nanocrystalline core significantly cuts no-load losses – the manufacturer quotes around a 30% to 50% reduction compared with a standard core – a significant consideration for users who run gear for hours on end. Real-time monitoring and intelligent control also allows the output to remain at a stable voltage despite variation in the input, important for companies in fields such as medical and electronic equipment.
The result. In Belize, the unit offers reliable 380V power for industrial production, commerce and everyday life without the worry of damaging equipment or reducing its lifespan if the frequency isn’t exact. Reduced no-load losses mean more power is being utilized over the lifespan of the equipment. This is a win for Belize which has a focus on sustainability.
Yes. The Jinma 190V to 380V variable frequency power supply features 50Hz/60Hz dual-frequency control and delivers a stable 380V output on either system.
Any equipment designed for a 380V supply, including production machinery, commercial systems, and voltage-sensitive devices in medical or electronics applications, provided the unit’s capacity matches your total load.
According to the manufacturer, no-load losses are reduced by approximately 30% to 50% compared with conventional cores. Actual savings depend on operating hours and load profile.
The unit uses advanced power electronics and an intelligent control algorithm to monitor input voltage in real time and adjust the output, helping maintain a steady 380V level.
