Lex Rack Mount Power Distribution Units w/ (24) Returns & Power In/Thru L21-30P Twist Lock Terminals [

Lex Products rack mount power distribution units equipped with an L21-30 In/Thru and 24 returns are specialized, high-density power solutions designed heavily for touring AV racks, broadcast environments, and theatrical staging. These distribution modules (often part of the PRM or PowerHOUSE series) are designed to take a 30-Amp, 3-phase 120/208V feed and split it across multiple branch-rated 120V circuits. This specific configuration feeds a massive bank of 24 return receptacles (typically NEMA 5-20 Edison duplexes, though sometimes Neutrik powerCON) on the rear and front panels, allowing you to power a heavily populated rack of amplifiers, video processors, or networking gear from a single unit.

The defining feature of this configuration is the L21-30 "Feed-Thru" port. This locking pass-through receptacle allows operators to daisy-chain multiple equipment racks together off a single primary 3-phase power drop (provided the total amperage doesn't exceed the 30A-per-phase limit). Housed in a fully enclosed, lightweight yet rugged anodized metal chassis, it provides internal branch-circuit protection via premium thermal-magnetic circuit breakers that won't nuisance-trip under the hot ambient temperatures often found inside crowded server or amp racks.
