Technical Data Sheet 

The difference between Low Frequency and High Frequency UPS 

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.

Product Functions and Features 

 • The batteries of the CDD series 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.

 • IGBT SVPWM (Space Vector Pulse Width Modulation ) technology with 100% input to output isolation ensures complete safety of load. Quick transient response ensures enhanced crest factor allowing connectivity to more computers without rebooting problem. The SVPWM technology upon the IGBT power switching tube enhance the utility of the DC voltage by 15% and simultaneously eliminate the harmonic content by a large proportion, comparing to the conventional SPWM (Sinusoidal Pulse Width Modulation ) technology.

 • Dual DSP (Digital Signal Processor) basing on ART@Cortex TM-M enables overall digital control on UPS process of rectification and inversion and the charge and discharge of the battery. The machine is equipped with LCD screen, an emergency switch and physical memory for information log.

 • The CDD series UPS possess excellent loading characteristics by generating high precise output and firmly resisting to multifarious surges, so as to secure constant power output even when power consumption leaps from 0% to 100% with no request shifting to bypass.

 • The UPS manage the control on each individual phase among the three phases separately by the means of rejecting the negative-sequence and zero-sequence components of output-voltage, it implements controlling the imbalance ratio of the three phases’ output-voltage and the Imbalance ratio <5% (under 100% imbalance loads).

 • 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.(*RPA function is optional)

 • Comprehensive protection functions with alarms for all faulty aspects including over-voltage protection and low-voltage protection for input and output, phase-sequence protection, over-charging and over-discharging protection for batteries, short circuit for output, over-hot protection and so on.

 • Self diagnosis program is built in the machine and display vividly on the 7" LCD screen, the program completely diagnose among the main circuits and key components and set alarm for any fault or defect.

 • With Auto Re-start Function, when AC working abnormally, battery mode can supply power to loads till shutting up automatically; when AC recovering, UPS will start automatically, and supply power normally, no need to start manually.

 • All circuit boards in the machine are processed by specially treatments of anti-dust, anti-humidity and anti-corrosion.

 • WIFI function device is optional for building in this machine. Wireless control through WIFI signals are workable for smart phones or tablet PC for both Android and Mac.
