CHADI UPS as the batteries are always connected to the inverter, so that no power transfer switches are necessary. When power loss occurs, the rectifier simply drops out of the circuit and the batteries keep the power steady and unchanged. When power is restored, the rectifier resumes carrying most of the load and begins charging the batteries.

The Double-conversion UPS provides a layer of insulation from power quality problems. It allows control of output voltage and frequency regardless of input voltage and frequency.
CHADI Online line UPS systems are available to suit different kinds of load / equipment.

CHADI UPS are designed to ensure that companies can protect their mission critical applications by maintaining a steady flow of energy under adverse circumstances. An uninterruptible power supply is an electrical apparatus designed to furnish emergency power even when other sources of input power fail, and they are indispensable tools within a huge number of unrelated industries. These devices differ from a standby generator or an auxiliary or emergency power system in that in the event of a disruption to input power, a UPS will provide near-instantaneous protection for mission critical applications in the form of energy stored in batteries.

The high cost of electricity is not a factor that businesses can afford to ignore when considering their overhead. Every company, no matter how large or how small, must monitor its power use in order to avoid consuming too much. CHADI UPS are known for efficiency and for saving not just energy, but money that would be wasted by less advanced devices that require too much power.

CHADI Online UPS makers provides an freelance, no break supply of fresh, stable, transient free uninterrupted power supply offer with output neutral secured to ground, defend essential hundreds against transmission line disturbances and loss of business power. The Online UPS given accurately controlled wave AC output with none line disturbances.

The CHADI Online UPS system includes uninterrupted power supply of a rectifier, associate motorcar float bodily fluid boost charger, battery backed electrical converter with below V, over V short-circuit protection along side a high degree of Input to Output isolation.

The award-winning UPS designed by CHADI act as advanced power managers, ensuring the availability of an uninterrupted power supply to protect hardware and mission critical applications. High-quality UPS function as an essential safeguard against many potential energy issues, including voltage surges and spikes, voltage sags, total power failure, and frequency differences. By making sure that their systems are set up to retain access to a stable power supply, even during failure events, companies can greatly reduce their costs while continuing to keep operations running smoothly.

Established in 1985, CHADI has grown into one of the pioneer suppliers of power supply system in China and undertook numerous projects for China National Defense, governments, police departments, banks, hospitals, telecom companies, Beijing Olympics,Shanghai Expo and etc..Since 1998, Beijing metro system has used CHADI power system for the communication system and hereafter the page of using foreign brands has been turned.CHADI people are keenly devoted to the research and development in the Uninterruptible Power Supply field and winning long standing reputation with reliable quality and worry-free service.

Back to the history before 1985 when CHADI's former roll was China State-owned Power Transformation Corporation, this group had been the first company and the biggest company working on the field of power transformation and power supply in China.

After the reformation of state-owned PTC, the reborn CHADI arises and advances with the pace of China new economic surge in the past decades, and grows into a large UPS solution provider.
