Product Description

Customer Question & Answer
Ask something for more details

Marine charging apply Pulse Width Modulation (PWM) or Pulse frequency Modulation (PFW) technology, being multiple-function swithing charging power supply with IGBT, MOSFET and PWM or PFM integrated controller as main parts. Heavy power frequency transformer with noise is not used, which makes the weight of the whole set be 1/4 of silicon controlled charger. The whole set of 3KW HDC charging power supply weighs 5 kilograms. The power supply also provides several function modules for matching. The whole set adopts smart cooling process, therefore the power supply could work reliably in engine room with the highest temperature. CDHD series and HDC series power supply meets all the sepcifications and rules of China Classification Society and basic standards of marine electric stardards.
Three stages of the automatic charging power supply are constant-current equalizing charge, constant-voltage equalizing charge and floating charge as shown in the following figure. The whole process of battery charge is to enter the mode of equalizing charge first and automatically finishes the constant-current and then constant-voltage charge. The equalizing charge is finished wen the current is near zero, and the mode should be transferred into "Folating charge" (manually or automatically). The trickle maintains the stataus of full charge. The setailed process of charge is as follows:
 Marine Charging Power Supply Hdc Series
Take the 24V lead acid batery as an example: the process is that when the battaries are connected and turned on, soft starting of the charging power supply is finished; voltage rises from 21.6V (lower limit of battery discharge); current increase steadily to rated value of constant current; charging power supply enters into process of constant-current charge; the charge voltage gradually rises to 28.2V (average voltage charge voltage), and the constant current charge usually lasts for 1-2 hours. Then the charing power supply enters the process of equalizing charge, and in the process the current gradually falls; the constant-current work of power supply ends. The power supply keeps being unchanged, and enters into the status of constant-voltage equalizing charge; the process lasts for 4-6 hours; as the current further falls to be 1/10 of the rated current value, the battery is automatically regarded as fully charged, and the power supply enters the stage of floating charge, i.e. The output voltage will be 26.4V and the charge current further falls to zero; then the power supply keeps the status to supply the self-consumption. The manners enable fast and equalizing charge of battery, and the charging power supply automatically switches into status of floating charge to maintain the usual voltage of battery and avoid overcharging, thus the method of charge without people's supervision is realized.

Remarks: the charging mode and charging voltage of the different type are different, the charging power supply in the
manual is only for lead-acid batteries, the other type battery charging power supply can be customized.
The battery capacity: under the standard temperature of 25 DEG.C, battery discharges in 10 hours rate, discharge current rate is 0.1ºC , single cell discharging termination 1.8V, the duration time multiply by discharge current is the battery capacity of 10 hours.
Battery charge current and battery capacity: average current of the battery is proposed 0.1ºC 1OA-0.2ºC 10A. For example, 200Ah battery, average current is 20A-40A.
