Telecommunications Batteries
| Item No.: | JBJPBA-4824 |
- LiFePO4 Battery 48V / 48AH containing a total of more than (group 2: 24A discharge 60 minutes, the cut-off voltage ≧ 40V)
- Batteries modules (including BMS) CE Compliance: EN61000-6-1: 2007, EN61000-6-3: 2007; batteries accord UL-1642
- 15 electrical batteries in series is 1 pack, each battery pack is not parallel with the number 1, all batteries use the same type of content
(1) High-pressure alarm: total voltage of 55.5V start alarm. Automatic discharge
alarm: less than 55.5V, more than 30sec
(2) Low Alarm: The total voltage 46V start alarm. Automatic discharge alarm: total
voltage 46V, more than 30sec or batteries voltage is below 2.2V (batteries fault).
(3) High temperature alarm: 65 ℃ start alarm. Automatic discharge alarm: temperature below 60 ℃, alarm eliminated.
(4) Over current alarm:
- (Charger charging current 20A) exceeds 30A start alarm. Automatic discharge alarm: Power up to 30A or less.
(1) The exception occurs when a single cell, the battery can not charge and discharge abnormality, and the rest work properly.
(2) Voltage protection: detection with single batteries for the units, with a total dry contact alarm detection voltage is different.
(2.1) when the single cell voltage is lower than 2.5V battery stops discharging rechargeable.
(2.2) when the single-cell voltage higher than 3.9V battery will not charge, can be discharged.
(3) High temperature protection: When the temperature exceeds 70 ℃ power protection,
the battery will not charge and discharge, when the temperature returns to below 60 ℃ recovery charge and discharge.
(4) Over-current protection: two battery section: 33A, power protection, has been
carried out; recovery charge and discharge current is detected again.
(5) When the battery pressure 4V, while still loaded with charging the normal power supply.
- power switch, LED signal lights (or other display capacity mode)
(1) after full charge LED is green 100%.
(2) lights from green to yellow 50%.
(3) lights from yellow to red light 10%.
2.
- Battery Case Material: Aluminum (thickness 1.6 mm or above).
- Nameplates in front of the battery case: both waterproof and dustproof
- processing.
- Battery total space dimensions (without handles): 400 * 150 * 380 mm (W × H × D) or less.
- cold swap mode (power supply connector and the connector at the rear of the
- socket engagement alarm).
- Front of a reserved power supply waterproof connector waterproof connector with alarm. (Provide link)
- Board shall have anti-corrosion treatment.
