APC by Schneider Electric PDM3520L2120-740 Concise Descriptor

Overview

The APC by Schneider Electric PDM3520L2120-740 is a 3-pole, 5-wire, 20A IT Power Distribution Module (PDM) designed for critical infrastructure within data centers and enterprise IT environments. It provides a reliable power interface for rack-mounted equipment, ensuring consistent power delivery to servers, network switches, and storage arrays. This unit is specifically engineered for environments where precise power management and distribution are paramount, such as colocation facilities or high-density server racks. The PDM3520L2120-740 offers a robust solution for managing power loads up to 20A at 208V/120V, utilizing an L21-20 twist-lock input connector for secure power termination.

Compatibility

This power distribution module is designed to integrate with standard 19-inch IT racks and cabinets. It is compatible with APC's own NetShelter SX, NetShelter SV, and NetShelter WX enclosures. While not tied to specific camera or NVR models, it serves as a foundational power component for any rack-based surveillance system requiring stable power for network video recorders (NVRs), managed switches, and associated network infrastructure. It is suitable for deployment with any equipment that requires a 20A L21-20 input connection and operates within the 208V/120V phase-to-neutral or phase-to-phase voltage range.

Installation Notes

Installation requires a qualified electrician to ensure proper termination of the L21-20 input plug into a compatible 20A, 3-pole, 5-wire twist-lock receptacle. The module's mounting brackets are designed for tool-less insertion into standard rack vertical rails, allowing for quick deployment. Ensure the rack's power infrastructure can support a continuous load of up to 20A. Torque specifications for any hardwired connections (if applicable to the specific installation scenario beyond the plug) should adhere to local electrical codes and standards.
