Stationary Power Distribution Unit (SPDU) 3-phase, 75-300 kVA Technical Handbook APC’s Stationary Power Distribution Unit (SPDU) was designed for application in various 3-phase environments. The SPDU can provide up to 11 sub-feed breakers, and offers the option of increasing the number of panel boards by adding sidecars. Top and bottom cable entry are standard. Other features include total front accessibility, K1-K20 transformers, and protective shielding.

Section 1: General Information Positioning statement The superior design flexibility of APC’s 3-phase Stationary Power Distribution Units (SPDUs) satisfies a wide range of customer requirements. The SPDU can deliver up to 300 kVA of power, and provides more sub-feed breakers per service area than any other model in its operational class. This translates into a highly efficient and effective distribution of power.
Section 1: General Information Features and benefits Space savings. • Smallest overall footprint of any model in its operating class. • Optimal operational and service features. • Service takes place solely through the front doors, so the SPDU can be positioned next to a wall or other equipment, preserving space for revenue-generating products. Performance. • Delivers up to 300 kVA of power. • Provides more sub-feed breakers per service area than any unit in its class.
Section 1: General Information Custom configurations and options Product SKUs. There are 21 SPDU product SKUs available. These are basically broken down into seven (7) levels of output power (75, 100, 125, 150, 200, 225, or 300 kVA) and three (3) types of transformers (K1, K13, and K20).
Section 1: General Information Sidecar(s). One or more sidecars (p/n PDSC100 for 75-225[K13] kVA units, and p/n PDSC300 for the 225[K20] unit and all 300 kVA units) can optionally be attached to the main unit (via hard bus) to increase the SPDU’s overall load distribution capability. The customer must also decide whether to add one or two 42-pole panel boards (p/n PDPNLPL1A) to each optionally ordered sidecar. Sidecars can be attached to either or both sides of the SPDU and daisy-chained, if necessary.
Section 1: General Information Floor jacks. A set of (four per unit) floor jacks (p/n PDFJ100) can optionally be applied to the SPDU (and each of its attached sidecars) to provide leveling and/or additional clearance for bottom cable feed. The jacks are offered in heights of up to 18 inches, and are adjustable from one to three inches above the base. Full-frame floor stand.
Section 2: Technical Specifications Overview of SPDU offerings Standard features. APC’s Stationary Power Distribution Unit (SPDU) combines power distribution with isolation and flexibility. A provision for top and bottom cable feed is standard. Other features include 100% front accessibility, K1-K20 isolation transformers/shielding, and two panel boards with up to 84 pole positions (or any of three panel board alternatives that allow sub-feed breakers to be incorporated into the mix).

Section 5: Ordering Process “Build to order” guidelines APC’s SPDUs are “built to order” as a means of satisfying each customer’s unique requirements. The customer is thus given total freedom in selecting an appropriate SPDU model and whatever features and options they would like to have included with that model. An added bonus of APC’s customer-oriented philosophy is the company’s willingness to respond to special requests via custom engineering.
Section 5: Ordering Process 5. The customer finally decides on any other options they may want to include as part of their SPDU package. These options include manual restart, a TVSS, custom painting, floor jacks, full-frame floor stand, and seismic bracing. For example, the customer opts to add manual restart (p/n PDMRS100), blue painted enclosures (p/n PDCP100) for both the SPDU and its sidecar, and floor jacks (PDFJ100) for both enclosures.
