User questions & answers

Question:	How tall are the digits on the LCD indicating the runtime? And is the LCD's viewing angle such that it can be read with the UPS on the floor
Answer:	The Blue display total size is 2" x 2" and sharp and clear. Digits for line voltage are about 1/2 inch and the run time is a 1/4 approx. bar above digits. I would say if you can see your digital alarm clock from where you want to place the unit you will be able to see quite well. Also UPS status can be displayed by supplied software with unit.
Question:	I have a harmon pellet stove Mo.# XXV start amps 4.2 run amps 2.8 will this unit be adequit to run unit till I shut it down
Answer:	I wouldn't try it, according to Ohm's law (assuming standard US 120 household voltage 120v*4.2Amps=Watts) your starting wattage is 504 which exceeds the maximum recommended wattage on this device. You should look for one with a higher rating.
Question:	Is there a UPS like this that can automatically power cycle the router when internet connection dies
Answer:	The UPS unit will maintain a/c power to all devices connected to the battery backup outlets of the UPS unit. Loss of internet connectivity is a separate issue which would be dependent on the "cable" or "dsl" etc service provider. You might need to reboot the router after internet connectivity has been lost.
Question:	Does this unit come with a compabible USB cable or does it have to be purchased separately
Answer:	It comes with a semi-proprietary cable in that the end that plugs into the UPS is like Ethernet. The other end is a standard USB so don't lose it.

User questions & answers

Question:	Is the unit noisy, ie is there a fan
Answer:	There is no fan on my BX1500M. Is quiet on Utility power and only a very low hum on battery power if you place your ear close to it.
Question:	Does the 1500va indicate it's amp hour (how many hours it will run?) ie 100 volts x 15 amps for 1 hour? or 100 volts x 5 amps for 3 hours
Answer:	The 1500VA/900watt rating has absolutely NOTHING to do with the run time. It is a rating of the maximum output level for a very short period of time. The BX1500M uses a 12 Volt 9 Ampere hour battery that means it stores 108 watt/hours of energy. The inverter (the electronic circuit that converts the stored 12 Volt DC power to 117 Volt AC power) is far from 100% efficient, and will not operate if the battery is near complete discharge, so the actual stored energy output for this device is 68 minutes at a 100 watt load. At the full load output of 900 watts the UPS will provide power for about 5 to 6 minutes before the battery is depleted and it shuts down.
Question:	Have a few months lost power and this goes out immediately. is there a set up that i missed? light on with power. thanks
Answer:	I did the same thing on my first unit, didn't plug in the battery. Went for a long time because the rest of the unit was working ok and I WAS SURE it would work if needed. It never would switch to safe shut down mode. FINALLY I opened the unit and found the battery disconnected ! Will make sure the next unit will have the battery hooked up as per directions.
Question:	Pure sine wave? or Modified
Answer:	It is in between. Though not pure sine wave, it has many little steps, vs Modified (modified square wave) which is simply 0 + 0 - 0 + 0 - 0 +... (3 status levels) A very good explanation and comparison graphs are shown at: https://linustechtips.com/main/topic/812247-best-ups/ Hope this helps.
