Uninterruptible Power Supplies

All UPS systems provide approximately 10 minutes of battery autonomy at full load unless otherwise noted. Please remember that battery time is not a linear factor: eg, a 6kVA/4.2kW rated unit will run a 4kW load for approximately 10 minutes or a 1kW load for approximately 1 hour. Battery time will also depend on the type & power factor of the load you are running. It will also be affected by equipment/ambient temperature.

Power Analysis and Recording

Fluke VR101 Event Recorder detects and records voltage levels brownouts and transient events: sag, swell, surge and droop. It is a 13A type plug top device which is programed with test parameters from the laptop and then left on site. Later, the collected data can be downloaded through the optical interface and analysed at some other time. Data may also be printed in a report from the laptop.

PowerLogger 200 is a fully loaded single phase 230V disturbance analysis system, sampling at speeds fast enough to capture half-cycle events. Fully programmable through laptop, this device measures volts, amps, power, power factor, crest factor, harmonics and frequency. Can produce graphs of all measurements and is able to record several days-worth of data.

Lab Equipment and Power Supplies

A wide variety of lab equipment including DC and AC supplies is available but, as many are used in our tech facility, they are allocated on a job basis only when customers are unable to source suitable equipment eleswhere. Full details are available on request.
