Detail 01
Regulation from 97 to 137 VAC
Input inside that window gets corrected toward nominal, so amps and supplies see steady voltage as the room load shifts.

FurmanP-2400 AR Voltage Regulator/Power Conditioner
1/4
Independent shopping perspective
The Korena take
39 lb rackmount voltage regulator with 14 outlets. For rigs on unstable AC that need the line held near 120V, not just filtered.
Strong match
Who this is for
- Venues and rentals where line voltage sags under load
- Large racks needing 14 protected 20A outlets
- Installs where gear runs unattended on questionable power
Consider the trade-offs
When to look elsewhere
- Small pedalboard or single-amp setups
- Anyone on stable house power who only needs surge protection
- Shallow racks — it runs 12 inches deep and weighs 39 lb
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Fourteen 20A outlets, twelve rear and two front
Enough for a full touring rack with two front sockets left for a lamp or test gear.
Detail 03
20 amp maximum current
Derates 170mA per volt below 120VAC, so a sagging line reduces how much you can actually pull.
Detail 04
39 pounds
Heavy enough that it needs rear rack support, not just front ears, in anything that gets moved.
Detail 05
Over-voltage shutdown at 145 VAC
Beyond the regulation window it disconnects rather than passing a damaging line through to your gear.
Detail 06
3.5 inch H, 19 inch W, 12 inch D
Two rack spaces plus depth for the transformer — check clearance behind the rails.
Final check
Know before you order
- 01Needs a 20A circuit and NEMA 20 receptacle; the cord is captive
- 02Rear rack rails or a support shelf are strongly advised at 39 lb
- 03Regulation transformers can hum audibly — keep it away from live mics
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01How is this different from a plain power conditioner?
It actively corrects input voltage between 97 and 137 VAC back toward nominal. A conditioner only filters noise and clamps spikes, passing low voltage straight through.
02How many outlets does it have?
Fourteen total 20A NEMA5-20R: twelve on the rear panel and two on the front.
03Will it run my whole rack?
Up to 20 amps at 120VAC. Below 120VAC input, capacity drops 170mA per volt, so budget headroom on weak circuits.
04How much rack space does it take?
Two spaces at 3.5 inches tall, 12 inches deep, 39 pounds. Plan on rear support.
