Isolation Transformer Based Power Conditioner 250W Line Noise Reduction Spike Suppression

Isolation Transformer-Based Power Conditioner - Superior line noise reduction and spike suppression

Model Number: IS250


  • Complete line isolation, noise filtering and surge suppression is ideal for sensitive equipment
  • 250 watts, 2 outlets, 6-ft. power cord
  • Compliant with the Federal Trade Agreements Act (TAA) for GSA Schedule purchases

Tripp Lite Isolator series isolation transformer-based power conditioners offer complete line isolation, continuous noise filtering and enhanced normal and common mode surge suppression. Internal low-impedance isolation transformer component with Faraday Shield offers 100% isolation from the input AC line. Secondary neutral to ground bonding eliminates common mode noise, providing an isolated ground reference for sensitive equipment and an inexpensive alternative to the installation of dedicated circuits and site electrical upgrades. Removes EMI/RFI noise, utility switching transients, background spikes generated by other on-site loads and utility or lightning related surge conditions. Additional surge suppression components placed at both the line input and transformer output combined with full line isolation offers continuous line filtering of a full range of power line noise in all modes. Continuous transformer filtering with no wearable parts uniquely reduces surges in the worst of power environments to harmless levels. Reduces 6000V IEEE C62.41 Cat A&B ring wave and combination wave test surges to only 0.5V common mode. Model IS250 offers 250 watts capacity with 2 widely spaced output receptacles, a 6-ft power cord, circuit breaker overload protection and lighted power switch. Rugged all-metal unit housing ships ready for upright tower or wallmount placement in industrial, medical, office or network environment.

Not for cleaning up generator output I have a standby natural gas fired generator in my home that runs when utility power is down. It runs a 20 minute test every week. During those 20 minutes, the UPSs (uninterruptible power supplies) on our computers keep switching back and forth to battery power, even though the frequency and voltage from the generator are correct. I thought an isolation transformer would clean up the output of the generator so that the UPSs would not switch to battery power. Wrong. An isolation transformer can eliminate spikes and high frequency distortion components, but (because the magnetic properties of iron are nonlinear) it generates distortion itself. The UPSs work better without the isolation transformer. September 5, 2013
Noticeably reduced the level of floor noise in my studio monitors Power in a home studio can be a nightmare. You have pipes in the walls, cable wires, and usually at least a little, if not a lot, of "dirty" power. I've been using Furman power conditioners and was getting irritated by the white noise I was getting, so I decided I'd try something else out. I just purchased the IS250 and as soon as I plugged my JBL LSR4326P monitors into it, I could hear a noticeable difference in the "floor noise". I definitely recommend this product to anyone wanting to clean up their power. I think it's a must when it comes to audio. June 6, 2013
Does the job. I had a hum in my new sub-woofer. After much searching, I narrowed my problem down to a house electrical issue. All circuits had the same problem. Once plugged in, no more hum. There are two outlets on this item, so when I add another sub-woofer, I'll use the currently open outlet. This is a well built unit that has worked flawlessly. June 13, 2012

I live in an older house and don't have a ground. I'm shopping for an isolation transformer to give me protection from surges, etc. Will this 250 unit be able to function if the 'plug' has no ground?

I was under the impression, from the product page, that this was a way to ask tech support a question, not 'post' it somewhere.....

Thank you.

Answer: 
My house does not have a ground on each three pronged outlet, but does have circuit box ground, I think that's code. Check there, mine is inside the wall, yet visible outside as it is "earthed", through the cinder block foundation, just above ground level.
This unit removed the hum I had.

Answer: 
Thank you for your inquiry. For the IS250 to function as designed requires that it be adequately grounded.

I have used isolation transformers and they usually emit a low humming noise. I'm thinking about getting an isolation transformer for my bed-side headphone audio system but would be bothered by any humming equipment.

Like to know if this product emits any noise. Thanks!

Answer: 
Thank you for your inquiry. The IS250 does emit some low level noise due to the transformer. However this product is designed so that the noise is not at a noticeable level.

220v input

I intend to bring several of these overseas (Europe, India, Japan).

If I plug this into a 220V wall outlet (I will use a plug adapter), will the the output be 220 V? Same if I plug into a 100V power outlet, will the output be 100V?

Answer: 
The IS250 will only support 120 vac input and at this time Tripp Lite does not have a 220 vac option of the isolation transformers.

We do have other products that may work for your application, for additional info please reach out to our presales applications team at 773-869-1234 option 1 or presaleshelp@tripplite.com.
