Question about Computers & Internet

I don't understand if my new UPS(Mercury-Elite650Pro Line Interactive) is getting charged or not. Do I ONLY switch on the main power supply?If I also switch on the multiplug adapter, orange light is on. Do I need to switch on the UPS?then green light is on. Does it mean that it is being charged?

Yes. you need to switch on the power plug to allow the charge. refer to the user guide, usually an orange light is showing the power ups do charge activity.

UNINTERRUPTIBLE POWER SUPPLY


UPS – UNINTERRUPTIBLE POWER SUPPLY
Uninterruptible power supplies provide protection against mains power faults to computer equipment.
These faults include voltage spikes/interference, over voltage and under voltage, mains supply interruptions and surge protection etc.
These faults can cause computer and electronic equipment that are connected to an unprotected mains supply to malfunction and/or sometimes fail.
A common problem, when burning Cds, DVDs etc. any slight power interruptions to the burning process will halt the recording process and rendered the disc useless.

There two type of Uninterruptible Power Supplies
The lower powered and cheaper type UPS are switch-over types, when the mains supply fails, the UPS switches over to the batteries and inverter in milli-seconds which then supplies mains power to the computer and peripherals. A faulty inverter circuit and or flat batteries won’t deliver standby power when the mains supply fails.
NOTE : The mains waveform from these UPS is a pseudo sine wave (i.e. not a true sine wave).
The true UPS types are usually the higher KVA units (over 1500 VA) that supply continuous mains power. The mains power is connected to a charger which charges the batteries and then the inverter draws power from these batteries and converts it to true sine wave mains power to the computer equipment, therefore there is no switch over time lag when the mains supply fails.

UPS - Battery Fault


UNINTERRUPTABLE POWER SUPPLY
Batteries in the UPS typically last 3 to 5 years and it depends upon several factors. Including the number of times the unit must go on battery power and environmental conditions. There are usually several batteries in the UPS and while the battery voltage may show 13 volts, this may only be a float charge/voltage and a true indication of the battery voltage and condition requires the batteries to be tested under a load. If one battery is faulty in a set of batteries it will causes the whole battery system to fail and indicate a battery fault. A faulty charging circuit will not charge the batteries and will also cause a fault condition.

Computer restarts as soon as power goes off, its not an ups . When i manually turn off the power to the UPS, it switches / relay works fine, but if actually if there is a power outage the relay does not...


Your question is slightly confusing. Do you mean that the computer is not powered by a UPS? If the computer is not connected to the UPS, then why have a UPS? If the computer is not connected to the UPS and restarts when you turn the UPS On, your circuit feeding the UPS is overloaded and the voltage dips. If the computer is connected to the UPS, and restarts when there is a power outage, the fault may lie in the reaction of the HP 800. This unit looks to be a line interactive unit and it is not a true on-line UPS. The line interactive and battery backup (no voltage regulation) units both should have a switch to battery power time of 4 msecs, or less. If this unit is faulty and the switchover time is longer, it will not continue to hold up the computer internal power supply. If you are trying to run a laser printer on the HP unit, it won't have enough output capacity.

When ups is on it willgo to falt mode we have conected in tv


I assue you connected the UPS to a TV to test the UPS unit.

These lower powered and cheaper KVA type UPS are switch over types, when the mains supply fail, the UPS switches over to the inverter in milli-seconds which then supplies mains power but the power waveform is a pseudo sine wave (ie not a true sinewave. A faulty inverter circuit won’t deliver power when the mains supply fails.

The true UPS types are usually the higher KVA units (over 1500 VA) that supplies uninterrupted mains power. The mains power is connected to a charger which charges the batteries and the inverter draws power from these batteries and converts it to true sine wave mains power therefore there is no switch over time lag from the mains to the battery.

Dead appearing ups/inverter


keep on your main switch. off all the lights fan and other electrical items, let that inverter get charge first
