Thunder Laser Uninterruptible Power Supply Guide

Sizing a UPS

When selecting a UPS you should look at one that has a large enough output capacity with a surge capacity buffer. Generally, for larger loads you will end up with a much larger UPS that will in effect offer a longer run time after power is lost. For the purpose of this article, we only want to consider power blips so we will not consider having 30-60 minutes of run time as a factor when trying to decide which ups to use.

Each machine in the Thunder line up will have its own needs. The older Nova/Mars/Mini 60 series with the heavy duty fan and chillers will be the ones with the most surge need (since the power draw when the exhaust fan kicks in or the compressor on the chiller starts will be the largest). The Aurora series will be the smaller loads since they are generally rated at about 6amps which is around 720watts and they utilize lower current draw exhaust fans.

You should size your UPS based on the current draw and voltage. Most UPS will give a Wattage output value: Thunder Laser Main Power Requirements

Some suggested UPS's:

We do not currently recommend having a 120v UPS power a 220v laser.

There are many brands available from Outkitel, Fossibot, Oupes, Bluetti, Jackery, Vtomann etc. Each brand may have different offerings and sizes. Be sure to pay attention to the 120v outlet (if you need 20amp) and the specs. Confirm your machines load by checking the Amps listed on your serial plate. If you run multiple machines off a single ups or additional equipment like a computer/switch/monitor you should account for that load.

Machine	Wattage Recommended min (Nominal/Surge)	UPS Example
Bolt <6a	800W/1200W	Jackery 1000
Nova Plus 60w/80w	1800W/2200W	Jackery 1500
Aurora Series <6a	800W/1200W	Jackery 1000
Legacy Nova w/ 20amp Plug	2400W/3200W	Jackery 3600
Nova w/15A Plug	1800W/2400W	Jackery 1500
Bolt Pro/Odin w/15Amp	1800W/2200W	Jackery 1500

Additional UPS considerations

Surge/Noise Protection

All the three UPS systems possess surge suppression and line noise filtering functions to shield the equipment from damage caused by lightning, surges, and electromagnetic (EMI/RFI) line noise. Particularly, the online UPS system offers superior protection on account of the double-conversion operation that isolates equipment from problems on the AC line.

Transfer Time to Battery

During an outage, a 2 to 10 milliseconds can be expected in offline/standby UPS systems. Line-interactive UPS systems typically transfer in 2 to 4 milliseconds, faster enough to keep all but a small percentage of the most power-sensitive equipment operating without interruption.

The online UPS system does not have a transfer time, because the inverter is already supplying the connected equipment load when an outage occurs.

Voltage Regulation

Line-interactive UPS systems use automatic voltage regulation (AVR) to correct abnormal voltages without switching to battery. When voltage crosses a preset low or high threshold value, this type of UPS will detect and use transformers to boost or lower the voltage by a set amount to return it to the acceptable range.

Online UPS systems adopt a more precise method of voltage regulation: continuous "double-conversion" operation, isolating connected equipment from problems on the AC line, including blackouts, brownouts, over-voltages, harmonic distortion, electrical impulses, and frequency variations.

When not operating from the battery, line-interactive UPS systems typically regulate output within ±8-15% of the nominal voltage (e.g. 120, 208, 230, or 240 volts), whereas online UPS systems typically regulate voltage within ±2-3%.
