Is it possible to adjust the output voltage in

Our mains supply is 220VAC with frequency 50hz in India. Is it possible to adjust the output voltage in Microtek Heritage 600 UPS? The output voltage reads on a DVM 255VAC!!! and the mains voltage reads 233VAC, the frequency reads 49.5hz also the telephone sockets at the back do they help?

SOURCE: 50Hz to 60Hz conversion

Hi, Your idea is basically sound and should work as long as the UPS originally is designed to produce 240V 60Hz and has its own built in timebase. The reason is that the input as long as the voltage matches makes no difference (50 or 60 Hz). By design, the UPS converts the input voltage to DC to charge the internal battery. The battery then powers an electronic circuitry that produces the 240V 60Hz. The input is then isolated from the output in terms of frequency. This is a common design, however, there are some (not many) that uses for its local oscillation sampling from the source and therefore will replicate the input frequency to its output, but very rare; it's better that you know they exist. Hope this be of some help/idea. Post back how things turn up or should you need further information. Good luck and kind regards. P.S. The only problem with 50 and 60 Hz is heat buildup which is tolerable and still within safe parameters. The only time the 50/60 HZ makes a big difference is when motors are used, timers such as in the early designs of microwave ovens, washing machines, etc., pumps and other highly inductive consumers. Most electronic devices converts the AC input to DC and therefore the frequency has negligible effect. Of course others may see it differently.

SOURCE: Changing input frequency of Powerware 9315-80 Model 65 UPS

Unfortunately, it seems that you UPS is mostly designed for 60 Hz. However, there seems to be an exception for 380-415V input / 380-415V output where 50 Hz is supported.

Of course, 380-415V is not usable for IT systems as is, you would then have to transform it back to 208V or whatever voltage your infrastructure is requirering.

Check out the table at page 2 of this document:
http://www.armspower.com/Products/Powerware/Powerware9315/Powerware®%209315-80%20UPS%20Data%20Sheet.pdf

One thing that is not specified in this document is if the UPS can be easily switched from one input voltage to another or if you need to replace some parts.

Hope this helps.

Smart UPS VT 10KVA fault "Mains Not Available. Input Freq/Volt Out of Range". All phases input and output giving the expected voltages 240V and frequency OK at 50Hz.


Sounds like you hooked up the input to the UPS on the bypass. Either way either way your input is not there. Also make sure you configure the UPS prior to placing online.

Problem with Compaq UPS T1000h


I had a problem like this one, check the voltage from the generator , if the output from the generator is to high (over 240 Volts european standard voltage), the voltage protection (VDR resistors ) will brake the fuse to protect your UPS.
and also check the frequency of the generator, it has to be very stabile around 50HZ (european standard frequency)

Ups does not work on home generator


As a Ups manufacturer, I suggest the following: check the output frequency of the generator, it shout be 60hz +/- .5hz

Mains frequency is lower


open the case and look at the clock ic.  find the datasheet on the internet. this usually involves placing a jumper to ground for 50Hz operation and opening a jumper for 60 Hz operation.

JCR-160 clock radio Clock running slow


The clock works off the frequency (hertz). In US the electrical wave frequency is 60HZ/sec and in India and many other countries 50HZ/sec. Hence, the clock slows down about 6 seconds or so every minute.
