GESS PMI Rectifier DC Battery Charger

High Protection GESS DC chargers are SCR controlled AC/ DC rectifier with automatic constant voltage and constant current ability. All operations are controlled and processed by micro controller. The load is protected against the failures of the DC charger since the load is fully isolated from the system. Current module is used instead of shunt resistor so the output ripple is low and fully isolated. Input and output can be switched by circuit breakers individually. It has self protection against over temperature. The alarm contacts can be used for external system in the case of any anomaly. Features at a Glance • Useable as DC Current Source or DC Battery Charger • Microcontrolled • Adjustable Output Current • Adjustable Output Voltage • Adjustable Float and Boost Charging Voltage • Adjustable Timer for Boost Charging • Individual Output for Battery and Load Electronic Over-Under Voltage, Reverse Voltage Protection • Over Temperature, Short Circuit Protection • Parallel or Serial Connection • Thyristor Controlled and Full Automatic Systems with Isolated Input Transformer • Dry Contact and Indicators DC Ripple < 1% Input and output are protected with MCBs and all settings like boost charge, floating charge and battery charge current can be adjusted via front panel touchpad digitally. DC output is filtered by L/ C, so DC ripple at full load always slower than 1% to increase battery life. All rectifiers have standards low-battery and rectifier failure alarm. Parallel or Serial Connection The Charger has a modular design to provide service and maintenance simplicity. The outputs of the Battery Chargers can be connected in parallel or in series based on the requirement ( N+ 1) . Automatic Boost/ Float Charging Output current, boost and Float Charge Voltages are adjustable on the control panel easily. The Timer is a decrementing counter by one minute. The Charger output gives the boost charging voltage by setting the timer to any value larger than zero. The Charger returns to floating voltage level when the timer value reaches to zero. Wide Range of Use DC chargers are ideal for transformer energy distribution centers, gas oil energy distribution centers, natural gas energy distribution centers, mining industry security and lighting, building automation systems and for special telecommunication applications. Automation Alarm Contacts Mains switch failure, battery switch failure, load switch failure, low battery failure, low output voltage, over output voltage, mains failure, charger failure, over load, over temperature, low level electrolyte and earth fault alarms are among the ones that are available to be used in automation systems.
