How Many Tubular Inverter 200 Amp Batteries Are Needed for the JMC5A Ni Oxygen Concentrator?

When configuring your system for an oxygen concentrator like the JMC5A Ni, it is crucial to understand the power requirements to ensure safe and efficient operation. This article provides a comprehensive guide to selecting the appropriate number of tubular inverter 200 amp batteries for your JMC5A Ni oxygen concentrator, based on its VA rating and input voltage.

Understanding the VA Rating

The JMC5A Ni oxygen concentrator operates at a specific voltage and current. According to the product’s nameplate, it has a VA (volt-amperes) rating of 220 V ~ 230 V and a 50/60Hz input voltage. Its input power (VA) is 390 VA. The VA measurement is important because it indicates the apparent power needed to operate the device, which is the product of the voltage and current.

Calculating the Required UPS Output

To determine the required UPS (uninterruptible power supply) output, follow these steps:

Identify the VA rating of the JMC5A Ni (390 VA). Select the appropriate UPS based on the VA rating. According to industry standards, you need an 800 VA or 1 KVA UPS. If a 500 VA UPS is available, it can also work but may not provide enough reserve capacity.

Determining Battery Load and Backup Time

Next, let's calculate the battery load and determine the backup time:

The battery load can be calculated by dividing the VA rating by the system voltage. In this case, the system voltage is 12V (assuming a common 12V battery), so the load is 390/12 32.5 amps. If you have a 200 Ah (ampere-hour) battery, the backup time can be calculated by dividing the battery capacity (200 Ah) by the current draw (32.5 amps): 200/32.5 6.15 hours.

It is important to note that fully draining the battery is not recommended to maintain its longevity. For optimal performance and battery life, it is advised to only discharge the battery to 50-60% of its capacity. This means the actual backup time will be approximately 3 to 3.5 hours.

Scaling Up for More Backup Time

If you require more backup time, you should increase the number of batteries:

To extend the backup time to 4 to 4.5 hours, you would need 1.5 times the capacity of 200 Ah, approximately 300 Ah. To get an 8-hour backup, you would need 2.5 times the capacity, approximately 500 Ah.

Selecting the UPS Input Voltage

The input voltage of the UPS should match the battery voltage, which is typically 12V, 24V, 36V, or 48V. Here are the UPS selection guidelines based on battery input voltage:

For a single 12V battery, select a UPS with a 12V input. For two batteries in series, select a UPS with a 24V input. For three batteries in series, select a UPS with a 36V input. For four batteries in series, select a UPS with a 48V input.

Conclusion

In summary, to ensure the JMC5A Ni oxygen concentrator operates effectively, you should use a tubular inverter 200 amp battery system. The specific number of batteries depends on the total capacity required for your backup time. By carefully selecting the appropriate UPS and battery configuration, you can guarantee reliable operation and extended battery life for your system.
