Device for monitoring UPSes.. |
|
|
Hi there..
We have some very large, very, very expensive Hayley Industrial
Electronics UPSes... Amazingly these UPSes have NO method of us getting
telemetry off of them as they exist now! They only indicators we have
are the analogue guages on the front. These guages measure the load in
Amps, Voltage, and frequency. We'd like to measure the following
conditions within the UPSes, and either have that information accessible
via a serial device or on the network (Items with a * are available on
the analogue guages):
- Input voltage
- Input Cycles
- Cabinet operating temperature
- Battery plant operating temperature
- Battery plant voltage level
- *Output Voltage
- *Output Amps
- *Output Cycles
If anyone knows of anything we can use for this purpose, I would
appreciate any input... Thanks!
Regards,
Richard.

For any one of the above, you could use an external device such as a
voltmeter. There are some models that have either a GPIB interface, or
built in Ethernet. An external ammeter could also measure current.
I don't know about measuring cycles per second. That requires a more
costly instrument such as a digital oscilloscope/signal analyzer.
To use one instrument to measure all of the above is difficult. It would
require some kind of switch to measure different input sources.
Some sites that might have more information on such matters are:
www.agilent.com
www.ni.com
There is a considerable market for industrial control and remote
sensing equipment. That might be worth investigating as well.
