I also use a variac to precisely set the wattage. Then I plug how many ever incandescent lights that I need for the load.

MAC PRO POWER SUPPLY SOFTWARE CHECK UP SERIES

I use that in series with a car inverter. I use a "Watt's Up" meter from RC electronics. You can buy expensive battery testing rigs but here's my high precision, low dollar setup: Both have excellent service and their batteries have always been "fresh." (They haven't been sitting on their shelves for over 6 months.)īTW, most desktop UPSs will let you change their battery while they are still plugged in. I highly recommend tnrbattery for the NPX-35 and AlphaSource for the NPX-80. With batteries, heavier is always better. An 8AH CSB battery weighs 1.5lbs less than the Yuasa NPX of the same physical size. I've found that most APC UPSs use either NPX-35 or NPX-80 batteries. That makes their spec sheet very handy for calculating UPS runtime also.

They have heavy plates and rate their batteries in watts per cell instead of amp hours. Their NPX series is built specifically for UPSs. I've nicknamed them Crappy Storage Batteries. Peel back the label on most APC batteries an you will see CSB. This isn't for everyone, but I also don't use manufacturer replacement battery packs. (I have crummy power at my office that is in a more rural area.) Desktop UPS batts get monitored and changed at a maximum of every 5 years. The server UPS batts get replaced ever 3 years no matter what and tested every year. Like other have said, I also have a spreadsheet of when the batteries were last replaced and the date stamped on the battery. You also know exactly when the UPS cuts out because the lights go off. That way I can combine them for a whopping 1300W total load. I use a 300W one for testing desktop UPSs and a dual 500W lamp model for testing the server UPSs. I test mine by using those construction lights that you can get at Lowe's and Home Depot. Not pushing any brand but the linke below is too a good best practices by HP. (some units have this on the front display).ĭon't test a UPS on a production servers with a single source of power, if you aren't 100% sure the UPS (and batteries) can handle the load. All you want to do with it at this point is monitor the UPS and Battery condition.

MAC PRO POWER SUPPLY SOFTWARE CHECK UP HOW TO

If you are unsure on how it works or how to configure it, test the software on a system (laptop is good) that you don't care if it get bounced or treated harshly, (especially if your batteries are old). Keep in mind that most software is capable of being configured to SHUTDOWN your system in the event of a power failure and/or when battery life is exhausted. If you have two sources of power, you can safely test the UPS by pulling the source power of the UPS or activating a "BATTERY TEST" assuming the UPS does a true online test (some don't)īe careful of the software. You should have one PS connected to an UPS and the other connected to either a second UPS or directly to utility power preferrably on a different phase or power source. The best case power failure setup MUST include servers with dual power supplies (PS). UPS testing is always an overlooked area until you need it.
