A power strip without a meter is a guess. You plug in one more device, it works, and you assume there is room for another. Then one day the breaker trips and takes the whole rack with it.
The Valiant Power Rack Mount Metered Power Strip takes the guessing out. It has a built-in volt and amp meter right on the front, 12 outlets in a mix of C13 and C19, and runs on 240V at up to 30A.
Reading the meter
The meter shows two numbers:
- Volts: what your supply is actually delivering. On a 240V circuit you will usually see something in the 230s or 240s. A reading that drops a lot under load can point to a wiring or supply problem worth checking.
- Amps: how much current everything plugged in is drawing right now. This is the number that matters for capacity.
To get watts, multiply the two. 20 amps at 240 volts is 4,800 watts.
How many amps is too many?
The strip is rated for 30A, and it should be on a 30A circuit. Because rack equipment runs continuously, keep normal load at or under 80% of that: 24 amps. If the meter is reading 24A during a normal day, the strip is full. Startup surges and peaks need the remaining headroom.
C13 and C19 outlets
With both outlet types on one strip, you can plug in most rack equipment without adapters.
- C13: standard servers, switches, storage. Use a C13 to C14 cord.
- C19: higher-draw equipment with a C20 inlet. Use a C19 to C20 cord.
Specs

Mount it where you need it
The 19 inch metal housing fits a standard rack, and the included ears and fittings let you mount it to a wall or ceiling too. That helps in mining spaces and workshops where equipment sits on shelving instead of in a cabinet.
A simple load check routine
- Before adding new equipment, note the current amp reading.
- Look up the new device's max draw in amps at 240V (watts divided by 240).
- Add them. If the total is over 24A, the new device goes on a different circuit.
Want a 1U unit that also shows watts and comes with a choice of breaker or no breaker? See our 30A 240V Metered 1U Rack PDU.
Frequently asked questions
Can I use this on 120V?
No. It is designed for 240V.
Does it come with mounting hardware?
Yes, ears and fittings are included.
Why does my voltage reading change during the day?
Small swings are normal as loads in the building change. Large drops under load are worth having an electrician look at.
