FAQ

Ups uninterruptible power supply, backup type.
Start with the battery, multimeter DC file, the pen and the battery pole, see the voltage is normal. Boot to see what changes in voltage, if pulled down, the battery is a problem.s
How long can the power supply be used?
I suggest you buy energy storage cabinet! The use of solar energy and electricity storage, Storage battery capacity 2400WH Output power 2000W Inverter output voltage 220V 2400WH large capacity battery for refrigerators, notebooks and LCD televisions and other conventional household appliances work up to ten hours Steel shell, shock, dust, water, good pressure Product Size (mm) L600 × W600 × T800s
What is UPS uninterruptible power supply? In which areas
UPS is the uninterruptible power supply, is the battery (mostly lead-acid maintenance-free battery) and the host connected to the host inverter through the module circuit to convert DC into the mains of the system equipment. Mainly used for a single computer, computer network systems or other power electronic equipment such as solenoid valves, pressure transmitters, etc. to provide a stable, uninterrupted power supply. When the mains input is normal, the UPS will be powered by the mains supply to the load, this time the UPS is an AC mains regulator, and it also charge the battery to the machine; when the electricity interruption (accident power failure) , The UPS immediately to the battery DC power, through the inverter zero switching method to continue to supply 220V AC load, so that the load to maintain normal work and protect the load soft, the hardware is not damaged. UPS equipment is usually too high voltage or voltage can provide protection.s
Hills UPS Power 20K delay 2 hours how much battery
Need 20kva * 2h = 40kwh battery to 12v100ah battery, need: 40000vah / 1200vah = 34 Consider the input voltage, assuming 12 * 16 = 192v, then the two groups of 16 series and then a total of 32 parallel. Actual calculation to consider the power factor, efficiency, the actual operating power and so on.s
How to choose the right UPS power supply?
Can put your device power w and delay request, ask me.s
What kind of money is needed to monitor the UPS power supply for the system, which is a good brand
I follow the conventional calculation:      General camera CCD board power in the 1 to 2W or so, such as infrared camera, infrared light power 2 to 15W range, 60 camera estimates 10 * 60 = 600W;     4 video splitter 4 * 5 = 20W,    1 video matrix controller 300W,    4 hard disk video recorders are generally about 15W that is 15 * 4 = 60W,    A server dl388 standard 460W,    5 sets of 22 "display power: 50 * 5 = 250 W. a total of 1690W, plus redundancy (to prepare for system upgrades with) the maximum count 1900W. I suggest you use the most cost-effective mountain C3KS machine, the output power of 2100W, 8 38AH battery delay of 90 minutes or so, a set of less than 5000. Mountain C3K machine's standard machine delay of 10 minutes or so, the price of less than 3K.s
UPS power supply 10KS machine, delay for one hour. How much battery is used
Battery capacity ah = load capacity / 0.7 (discharge factor) / efficiency (depending on the efficiency of the UPS you buy) / battery voltage * emergency time (hours) because you did not tell me the specific load and your UPS efficiency, only Your own calculations.s
UPS power host capacity of 10KVA, the battery is 100AH 32 section,
According to the information you provide, the battery is 32 12V 100Ah, the load power of 200W; then the UPS power supply time is calculated as follows: 1.UPS battery discharge when there is a protective voltage (that is, the minimum voltage of a single battery) is 10V, then a group of batteries minimum voltage of 32 * 10 = 320V, the inverter efficiency is generally taken 0.9, then the maximum discharge current of the battery Is 200 / 0.9 / 320 = 0.69A; the average discharge current of the battery is 0.69 * 0.8 (correction factor) = 0.55A 2. Discharge rate = 0.55A / 100Ah = 0.005C; according to the battery discharge curve, the corresponding discharge rate of the corresponding discharge time. General lead-acid batteries are 20 hours discharge rate (more than 20 hours on the abnormal discharge, 20 hours after no discharge curve, and also find the corresponding time): the discharge rate of 0.05C can last 20 hours. The above system has a discharge rate of 0.005C for at least 20 hours. 3. General lead-acid batteries do not have such a small discharge rate to discharge, easy to cause the battery depth of discharge damage to the battery. Recommended battery capacity to reduce or increase the load power, improve system efficiency.s
