![]() In terms of powering stuff off the UPS, you want to have the fanout in the DC power supply, not the UPS. (OK, I have an active sinewave tracking filter in front of the IT gear but that was just because I had one at hand). I make a point of having zero of these things in the house, and it's been just as effective as having a MOV-based protection device on every outlet. To save having to type all this up I'll link to. Nonconforming MOVs in a surge protector connected to a UPS may cause the UPS to report an overload or a short circuit alarm.Įven beyond that, MOV-based "protection" is garbage, someone figured out they could charge more for a power board by strapping a ten-cent MOV across it and now everyone feels they need to do it. Krispkiwi: >Surge protectors utilize MOVs (Metal Oxide varistors) in their circuitry. If you have any problems (you won't) Just use a cheap power board (taking my previous comments into account) your UPS is the best surge protection you can have anyway. ![]() Unless you are in an area with very high harmonic content (your UPS is in a factory) forget about it. PDUs use and distribute the available amperage more efficiently, allowing your equipment to receive the best available power to maintain operation." PDUs evenly distribute the amperage among the outlets, while the UPS will filter the power and provide surge protection. If you need to supply additional receptacles on the output of your UPS, we recommend using Power Distribution Units (PDU's). Surge protectors filter the power for surges and offer EMI/RFI filtering but do not efficiently distribute the power, meaning that some equipment may be deprived of the necessary amperage it requires to run properly causing your attached equipment (computer, monitor, etc) to shutdown or reboot. ![]() Nonconforming MOVs in a surge protector connected to a UPS may cause the UPS to report an overload or a short circuit alarm. Surge protectors utilize MOVs (Metal Oxide varistors) in their circuitry. When the UPS switches to battery, it may be unable to support the equipment attached, causing a dropped load. This can cause a user to inadvertently overload their UPS. the big red shed used to sell those (may still do) and they are are very bad they are the ones you see burnt outĪPC has got this on their website "The noise filtration circuitry in a surge protector can effectively "mask" some of the load from the UPS, causing the UPS to report a lower percentage of attached load than there actually is. also if you by a power board that seems hard to but the plug in the first time but super easy the next time. it will make no difference at allĭon't worry about it. If it is super flash it will have a VDR across the conductors. A power board only has a thermal circuit breaker.
