Product description The current booster is used on checking current transformer,to be the power source supply once current for current transformer or to be other 50Hz single phase current source device. Technical index Temperature Humidit Capacity: 20kVA Specification Weight: 75Kg Allow long-term work on the rated current Allowable overload 1.5 times,30 minutes of continuous work. Feature This PSLLQ is make up of input Winding(220V), output winding below 100A and CXRZ. Output current indicated on the nameplate is defined the rated current that through winding allow to pass.When CX many circles, the rated current its permitted to pass through will inversely decline. The value which ouput capcity divided by product of output current and each circle voltage was the biggest circle number allowing. The current booster is designed to provide the primary current power supply for the current transformer when verifying the current transformer or as other 50HZ single-phase power equipment. The current booster for transformer verification is suitable for power departments such as power testing, power measurement, and power maintenance. The current booster is developed and produced according to the industry standard of transformer error testing, and is used as a current transformer to verify the primary current of the current transformer. The output current can be customized according to customer requirements. The lifter is equipped with casters for easy on-site movement.
Basic Parameters Dimensions: 201 x 99 x 35 mm Weight: 333g Adapter Input: AC 100 ~ 240 V Output: DC 24V 2.65A Display mode Segment LCD with white backlight + LED in red and green Function Introduction Charge Active, pre-charge, constant current and constant voltages are the stages of charging mode. The initial charging mode depends on the battery voltage, so active and pre-charge don't happen to every batteries. For charging mode and current, please refer to the paragraphs of charging mode and charging current on page 2 & 3. Tester will stop charging if one of the conditions below was met. 1) Remaining capacity 99% & current intensity = 0 2) Remaining capacity = full charge capacity 3) Current intensity reduce to end charge current when constant voltage charge 4) Remaining capacity reach up the set value Discharge Constant current discharge for double loads Inner load: 0 ~ 1000mA, adjustable continuously via Battery Manager External load: 0mA, 500mA, 1000mA, 1500mA, 2000mA, five gears with dip switches offered Tester will stop discharging if one of the conditions below is met. 1) Remaining capacity set value 2) Voltage set value 3) Current intensity reduce to zero Remarks: Many batteries can not measure exact current intensity, which cause an else current value appears after you set a value. However, the actual discharging current is the same with your set value. Test Testing time is 12 seconds and the purpose is to check both the charging and discharging performances. After finishing test, LED flickers with green color and LCD reports the test result. Normal: Test OK Shown on LCD Abnormal: Test NG Shown on LCD Possible causes and solutions for the abnormal: 1) Cause: battery voltage is too low to discharge Solution: try to charge the battery to raise voltage 2) Cause: remaining capacity is too full to charge any more Solution: try to discharge the battery to reduce the remaining capacity 3) Bad contact of battery connecting wires 4) Damaged battery 5) Tester trouble Capacity Correction The battery capacity value in the battery management chip will different from the actual capacity after a battery goes through many recycling cycles. It will affect the use of the battery when the difference reaches a certain degree. Capacity correction is to deep discharge a battery and then fully charge, which will correct the capacity value in the battery management chip. Remarks: Discharging current can be set via Battery Manager. Deep discharge will cause a battery losing communication with tester, so battery dropping phenomenon may happen in the discharging process if the end capacity and voltage are set too low. In such a case, active charge will make the battery work again. 50% Capacity CD50%: charge firstly, and then discharge to 50% capacity DC50%: discharge firstly, and then charge to 50% capacity Online Functions Tester can be connected with master machine via a USB port. Users can monitor, control and set parameters via Battery Manager software in the master machine. Monitoring Battery information can be monitored via three windows. 1. Home screen Battery bar and brief information can be read on home screen. 2. Battery detail information window Show smart battery data in real time and the data can be saved and printed in image format. 3. Battery graph window Voltage, current and capacity are traced in curves. Control Battery Manager can control slave machine completely. Right-click menu on the battery bar includes the related commands. Attention All the functions of charge, discharge, capacity correction and 50% capacity are comply with the charging discharging conditions, which are showed on function introduction paragraph in page 4 & 5, so parameters should be set reasonably. Especially, deep discharge will cause a battery losing communication with tester. Others 1. Active cooling 2. Active batteries of zero voltage When a battery is deep discharged, the discharge protection circuit will start up and the voltage in the battery connector will become zero voltage. In this case, an appropriate voltage should be supplied to active the battery. 3. Battery identification Battery information can be read from battery management chip after establishing communication. 4. Intelligent protection Against over-current, over-voltage, over-charge, over-heat and short circuit. 5. Fan Discharging mode: fan startup Other modes: fan startup when temperature above 48 Fan stop working when temperature below 40 6. Trouble alarm LED flickers in red color and current command stops when one of the conditions below happen. 1). There is not current for around 50 seconds when charge. 2). There is not current for around 25 seconds when discharge. 3). Charging time is above 8.8 hours. 4). Discharging time is above 9.9 hours. 5). Suitable for almost all laptop batteries, above 95% Structure Accessories 1).1 * adapter 2). 1 * USB cord 3). 1 * CD 4). 13 * connectors 5). 10 * cables 6). 10 * jumpers 7). 1 * loader Standard Export Carton
