Online Dual Conversion UPS 

 •  The batteries of the online UPS 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.

Low Frequency V.S. High Frequency 

 •  The HF UPS converts the battery DC to a high voltage CD, using a high frequency switch-mode converter. The HVDC goes through an array of FET transistors, which are driven to generate an approximation of AC mains. Cheaper ones make a stepped square wave, better ones a near sine wave. 
That HV converter is relatively lightweight. Most of the mass of such an inverter is the battery.

For the low frequency type, the DC goes into an iron power transformer (which is usually dual function as the battery charger transformer), and driven on the low voltage side to simulate AC, which directly comes out the 220V (or 120V) side of the transformer. The Iron transformer is usually pretty large, and a good part of the mass of the inverter, along with the battery.

Redundancy Parallel Connection 

 •  The advanced Synchronized Equivalent Flow Control technology manage rigid synchronized operation and equivalently divide the load current for each UPS unit in the Redundancy Parallel Array. These SEFC technology and RPA technology enhance the reliability of the UPS system to a highest level and promote the system lifespan to the most. CHADI technologies can well manage 32 units of UPS in the RPA arrangement.

About CHADI UPS

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.
