Hi all I am looking for the most cost effective UPS solution
for my HD24 unit.

Simply put I want to be able to stop the machine from shutting
down accidently in a power cut/outtage so the files remain intact !

If someone could recommend one that does not have to rely
on any computer OS.

My guess is that you just chain through the box and if the mains
cuts you get a chance to shut it down.

I don't have much experience in UPS but enough to know
I need one to be safe.

Many Thanks for your time. (I am UK based)

Would this be suitable?

Quote reasonably priced.

Take the number of Watts the unit produces then multiply it by at least 50% (25% if you're not into over kill) and that's how much power the UPS should handle.

Also, the larger the battery capacity the longer time you have.

Furthermore, many UPSs have software that can monitor the UPS... It doesn't run the unit, it simply monitors it.

Thanks, So it seems that the UPS itself not necessarily dependent on running
a PC/Mac

The HD24 uses 60Watts Maximum according to manual
(Uk volts is 240V AC so I suspect current drain is in the order of 0.25 AMPS)

so 120Watts and the UPS on my link says...

325VA (which I think is approx 325 watts as V x A = W)

That should do the job I think?

It is simply so I can just get a chance to switch the machine off in
a normal manner.

Make sure that whatever cheap UPS you buy can be returned if it makes your audio go Buzzzzzzzzzzzz

I posted this in another UPS thread...
This should explain a lot.

It really depends on the UPS.

As you may already know, UPS is an acronym for uninterruptible power supply (or source.) It’s basically a battery backup.

When you loss power this device maintains a continuous stream of power or at least until the battery dies out. The UPS switches from the utility power to its own battery power source almost instantaneously when a power failure occurs.

You incorporate the UPS between your (utility) power source and the equipment (the load) it’s protecting.

Remember, UPSs come in all shapes and sizes ranging from very small (around 200 VA) to units which will power entire systems in the megawatt range.

A UPS is not a generator -- It is not intended to handle very long power outages.


There are a few designs of UPS to consider -- On-line; off-line (standby) and other units that are not necessarily relative to our needs so I’m not going to mention them…

An on-line UPS continuously powers the load from DC batteries.

A standby (off-line) UPS powers the load when the power source fails by switching to it’s batteries until the power returns to an acceptable level. Most (garden variety 1 KVA or so) UPS units sold today are standby UPSs. Smaller standby UPS units usually make use of a modified square wave inverter and are more often than not designed for home use.

Double (or dual) conversion UPSs convert incoming AC to DC and then convert the DC back to AC connected to the load. The directly connected batteries provide an excellent filter for removing line noise by isolating the load from the incoming power and regenerate the sine wave. Because the equipment is always powered by the inverter, when power fails there is no transfer time. The UPS doesn’t need to switch from utility power to battery power.

Some UPS units are designed with an automatic voltage regulator that steps-up or steps-down the incoming voltage without switching to battery backup. The inverter is always connected to the output of the UPS. When utility power is there the inverter charges the batteries. When the utility power fails the UPS provides power to the load.

I hope this helped!

Thanks for your time replying.
