Equipping your UPS – Planning

Geek out: Power protection

Hot on the heels of discussing emergency power for mobile, it is time to discuss thoughts about Uninterruptable Power Supplies(UPS). These battery backup devices use heavy-duty batteries to power your electronics in the event of failure. When power is lost, it automatically powers using the batteries.

The first rule of UPSes is to always get ones with a removable/replaceable battery. You can get replacement batteries without much issue, although manufacturers would obviously prefer you replace the unit.

Our current favorite simple UPS for home use is the APC BE550G. This is an 8 outlet 550VA UPS. The green feature is a master outlet, which turns controlled outlets off when the master device is off. This is also a great green feature for various surge protectors.

However, the basic UPSes may have trouble with some power supplies, so mileage may vary. The issue is voltage regulation, and pure sine waves(necessary for Active PFC power supplies). There are more expensive UPSes, and more full featured ones. There are advantages to voltage regulation and purer power, but for some devices, it doesn’t matter.

Also, there are some issues with APC. We had used Belkin for a while, but had longevity and design issues. The Belkins we had tended to put the outlets on the top, which made placement difficult. There is also Cyberpower, which some people enjoy, but we’ve never tried one. We may next time.

This Cyberpower Unit looks promises, offering an LCD control screen with basic stats. This looks rather promising for non-computer uses.

These devices were originally marketed for computers. They were designed for safe shutdown of a computer and monitor, and things have changed. More people are using these to power other devices. In preparing for this post, we started reading reviews, and people are powering big screen TVs and other devices.

So, that is the sort of planning we want to discuss. For your cable modem, your router, etc. We have a simple 300VA UPS hooked up to our cordless telephone system, so it will work for a while in a power outage. As these devices are much lower power than a computer, many can run for hours with just a few necessary networking components hooked in.

The first step, even if you do not want to get into the wattage details, is to make an inventory of the devices you want to power. Make separate lists for extended outages, power hiccups, and voltage drops. Basically, most computers you may want to merely make a graceful shutdown, but you may want your networking gear to last for hours.

We predict, in our area, lots of people will be hiring electricians to install transfer switches for portable or permanent generators, after extended periods of power loss. But for the installation of a manual transfer switch will be close to a thousand dollars, if not more, as it requires disconnecting your house power in order to install the cutoff, and probably an adjustment of your house breaker box.

If your area isn’t prone to long power outages, you want to cover a few hours of power outage or irregular power, which is much less expensive than generators.

In the end, always buy UPSes with replaceable batteries, pick the devices that works for you, and do the advance planning.

What are your tips for planning for power loss with UPSes?

The Simplest Way to Save Energy – Shutting Things Off

This past week, prompted by increased utility costs, we became obsessed with the idea of vampire power. Vampire power, standby power, or phantom power, whatever you wish to call it, is the power a device draws when supposedly turned off.

So, we did the research. If you like tech, and we do, you can go with a Master Control surge protector. This is where the power draw on one outlet kicks in the power to other outlets. For top of the line right now, you can go with the APC Back-UPS ES BE750G 10 Outlet 750VA Master Control.

We rushed out and bought one of these things, which marries the idea with a UPS. One of the Battery controlled outlets can have your computer plugged into it, and when the computer is on, it flicks on three of the surge controlled outlets. We’re using it for our monitor and speakers on one system, and will be adding more to the controlled outlets as soon as we crawl under the desk to audit our wires.

Now, not everyone needs such a heavy-duty item, or even power protection. As an alternative, there is the Smart Strip LCG3. There are several variations that offer different numbers of outlets and/or coaxial or modem surge protection. One of the most useful options on this surge strip is a adjustment knob to adjust the master outlet’s sensitivity. The APC UPS also has three adjustment settings.

We couldn’t wait, so we went to the store and bought the APC Power-Saving Essential Surgearrest. It is that adjustment knob we missed. On the system we tried to put it on, it didn’t accurately detect the turning on of our low-energy thin-client PC. Of course, it may not have been designed for low-power systems, and lacks the adjustment knob of the Smart Strips.

BITS Limited, the company responsible for the Smart Strips, has not only come out with a 3rd generation version of their product designed with a “greater range of sensitivity and device compatibility for low-power devices like the Dell 800 series laptops and Mac Mini computers.” Which means it would have solved our problem with the APC. They all are accepting initial orders on a USB Smart Strip, identical to the LCG3 model shown above except in addition to the power outlet, this one will switch when the USB port receives power as well.

Being as we run multiple systems and are trying to be more energy efficient, for the low-power client and its peripherals we decided to go the low-tech route. We tried to find a switch to insert between the peripheral and the outlet, but no one seems to make three-pronged plug-in switches. So, despite Underwriter’s Laboratories’ recommendations about daisy-chaining surge protectors, we took the advice we found from Smart Strips FAQ and plugged a power strip into our UPS and then on to the components in question.

This is technically safe, as long as you don’t overload the circuit. The same people think an extension cord to a surge protector is dangerous and most of us do that. Our biggest problem was of a visual nature. How do you make the switch accessible without the unsightliness of the wires coming out in all directions?

One solution is another new product, the Belkin Conserve 10-Outlet Surge Protector with Remote Switch. Sounds good in theory. A surge protector you conceal with a wireless remote to allow you to turn things on. There are also all manner of surge protectors that hide the wiring.

We, on the other hand, went low-tech. We mounted the surge protector on the wall such that the switch was visible above the desk, but the outlets were below and weren’t visible unless you peeked under. Another option we considered was mounting the strip upside-down under the desk in such a position that you can flick the switch with little effort.

If you are more electrically inclined, you can build a plug-in switch using some basic electronics since no one seems to be selling one(comment if you’ve found one).

For those on the cutting edge of tech, semiconductor maker Rohm has developed a circuit that uses no power while in standby mode. They hope to start deploying it next year. In a few years, it could make it or circuits like it could make its way into most new appliances sold, reducing or eliminating the bulk of this problem.
