A high-power portable power frequency test power supply meets the practical needs of on-site work in the power system. This power supply uses a large capacity lithium battery pack as its power source.
The inverter then converts the battery power to output a stable 220V AC voltage with a pure sine wave at either 50Hz or 60Hz. This power supply can handle on-site testing needs and also serve as a backup power source for other field operations.
Product Features
The inverter uses advanced technology to ensure high power supply quality, allowing it to support various loads, including motors, air conditioners, drills, lamps, communication devices, and industrial equipment.
It is highly reliable, featuring advanced technology, a redundant design, and a power frequency transformer controlled by a CPU for stable performance.
The system offers complete protection, including input overvoltage and undervoltage protection, output overload, overcurrent, and short circuit protection, as well as over-temperature protection to handle high current startup loads.
The user interface clearly shows important information such as battery voltage, operating status, output voltage, frequency, load rate, and faults, with sound and light alarms for errors.
It is easy to operate with intelligent power on/off functionality, high automation, and user-friendly controls.
The internal components use a modular design, ensuring a simple structure and easy maintenance.
Its suitcase design makes it portable and easy to use on-site.
The system is energy-efficient, with low no-load current to save power.
The intelligent battery management system monitors and optimizes battery performance, increasing both its lifespan and efficiency.
