Great replacement for battery power packs
Tuesday, 13 April 2021  | 

After the battery pack dying on me I bit the bullet and bought the 30A Nevada power supply. Great move, nicely future proofed for me so hopefully it will cope with everything I need from it.
Note: this is a bench power supply, with no fixing holes on the base just rubber feet. But..... I removed the feet and using the same screw holes and self tapping screws, fitted some metal din rail to the power supply which extended past the length of the device and fixed it that way.

Quality product
Wednesday, 3 March 2021  | 

I was fed up of power issues, cheap wires and ebay 12v adapters causing disruption and frustration. So I bit the bullet and ordered one of these after reading the reviews. Used in connection with Lynx Astro cables this provides the perfect solution.

Admittedly, neither the power supply or the cables are the cheapest solution but you really do get what you pay for. Everything is well made. The power unit should provide years of service and scope to add as many peices of equipment as necessary. Highly recommended

Replacement for my Powertank
Wednesday, 13 January 2021  | 

My Powertank failed after many years of good use, however rather than replace with a like for like I decided to change it for the Nevada. This was mainly due to the fact I seldom venture away from home for my AP, also as I have a semi permanent observatory in the back garden then this would potentially be a perfect fit.
Although I've only used it twice, the first time at -8 and the second time at a balmy -6, both times I've had no issues whatsoever in the operation of this unit. Nothing really more to say on this, it does exactly as you would expect it to do, supply power to my full rig with no deviations in service.
On the service of FLO, it was again, as it has been for every other purchase I've made, exemplary, information and advice from FLO was spot on. I know we pay for the delivery and packaging over and above the purchase price but the standard and quality is very excellent and on the delivery it's self it was delivered on the day advised and on time.

Brilliant well made Power Supply
Wednesday, 14 October 2020  | 

Bought this as it has both a fixed and variable power output plus a meter which allows me to see what's going on. Extremely well made and very robust, should stand up to the rigors of outdoor observing.
now that winter is approaching my old power supply was beginning to struggle with all the cameras, dew heaters etc attached so this one should be easily able to handle any amount of power requirement up to 30A.
I have to say FLO's packing and delivery are second to none - the power supply was delivered within two days and the level of packaging was exemplary - it took me an age to find it amongst all the styrene chippings lol - they certainly make sure your goods arrive in perfect condition, thank you FLO for a first class item and service!
