Variable Frequency Power Supply, is not just a transformer. Instead of a power supply from grid, it converts the incoming power from AC to AC and modulates the voltage and frequency delivered to the load. Jinma uses IGBT modules for high frequency switching, which greatly reduces heat loss at continuous industrial operation for energy conversion. Powerful and high accurate sensor make the real time monitoring in the essence and intelligent digital control makes the output stable.
A variable voltage/frequency machine can be adjusted to suit the loads they are powering, thus optimizing energy use and reducing running costs, in contrast with fixed voltage solutions.

The input stage provides the voltage that Malaysian factories actually get. For an input of 415V, the first unit is connected directly to the local industrial source with no additional transformer or conversion equipment, with costs falling to the customer.
The output side is where the flexibility shows. Voltage can be adjusted across a 0–520V range, covering light loads at one end and heavy industrial equipment at the other:
The broad adjustment range allows one unit to supply two or more machines with different voltage requirements, thus preventing equipmen from damage and efficiency reduction caused by supply mismatch. Properly adjusted voltage provides long term benefit to electronic components and machine motors life-span.
Together these features show that the unit is built for stable performance, safe operation and convenient servicing — the three things a production line depends on.
Since the input equals the classic industrial supply, and the output can be varied over a wide range, the variable frequency power supply is used in the industry sectors of machining manufacturing, plastic processing, printing, textile and the equipment with automated assembly in Malaysia. The factory determines the power output according to its equipment parameters. Therefore, the effective power supply can supply the various state of the voltage and frequency for different production procedures with only one power supply.
This flexible structure allows to increase equipment utilization, to decrease the danger of failure and break caused by unstable voltage, and thus to achieve more efficient management and production. It provides a practical solution for small or medium enterprises and the bigger manufacturers in the development.
Yes. The unit accepts a 415V input, the standard industrial supply voltage in Malaysia, so no additional transformer or grid conversion is needed before installation.
The output is adjustable across 0–520V. Typical settings include 220V for lighter equipment and 380V for three-phase machinery, and any value within the range can be set to match your equipment.
When equipment receives a voltage it was not designed for, motors and electronic components run hotter, wear faster and fail earlier. A stable, correctly set output extends service life and reduces unplanned repairs and downtime.
