Optima™ Basic PDUs
Product SelectorOptima 5 & Optima 3 Basic PDUs ↑
These days, a “basic” PDU has simply come to mean a PDU which is not networked. However, that doesn’t mean the PDU has to be simple. Marway’s Optima PDUs offer more industrial capability than most commodity PDUs. Entry-level models provide solutions for budget-concious needs, but most models include options suited to more industrial-like environments.
The Optima 5 series products are a pre-designed, build-to-order range of PDUs for single-phase and three-phase applications in various enclosure forms. We’ve selected several of the most commonly requested features from a long history of creating custom products (such as EMI filtering, remote EPO, and metering) and packaged them into pre-designed, standardized product lines.
The Optima 3 Series is our light-industrial line focused on lower costs and faster availability. They’re designed for those use cases where “something less specialized will do,” but where a durable metal chassis, EMI filtering, and other light industrial features are needed.

520 Series
1U Single Phase ↑
The 520 Series 1U single-phase PDUs consolidate the most commonly requested 1U features and options into an array of almost 100 standard models.
- 120 Vac, 200–240 Vac, or 100–240 Vac 1Φ.
- 12 A, 16 A, and 24 A continuous duty ratings (15 A, 20 A, 30 A max).
- 5-15R, 5-20R, or high-tension C13 outlets (2 on front, 10 on back).
- Standard main power circuit breaker, indicator, and surge suppression.
- Options include current and voltage meter, remote switching and EPO interface, sequencing of two groups of four outlets, and an EMI filter.
532/533 Series
2U/3U Three Phase ↑
For higher power requirements, we have the 532 Series 2U and 533 Series 3U three-phase PDUs which provide the space needed for twist-lock connectors and individually breakered circuits.
- All models are 120/208 Vac 3Φ wye, 24/30 A, with an L21-30 inlet.
- Standard main power circuit breaker, phase power indicator, surge suppression, EMI filtering, and remote EPO control.
- Options for location of the inlet on the front or rear panel and a variety of outlets (5-20, 6-20, L5-20, L5-30, L6-20, L6-30, L21-30).
529/539 Series
0U Vertical PDU ↑
When rack space is at a premium, the vertical 0U 529 Series single-phase and 539 Series three-phase PDUs are installed at the back of the cabinet without using any of the traditional rack-mount spaces.
- Single-phase in 120 Vac, 200–240 Vac, or 110–240 Vac.
- Three-phase in 120/208 Vac wye.
- 12 A, 16 A, and 24 A continuous duty ratings (15 A, 20 A, 30 A max).
- Full-rack and short-rack models.
- Outlet types including C13/C19 combinations, 5-20R, and 5-15R.
Optima 320 Series ↑
The 320 Series 1U units are designed for the more common applications in development labs, test labs, remote or industrial-environment IT where there are fewer specialized control needs, but still a need for durable equipment with features to protect downstream equipment. With models for 15A, 20, and 30A, they’re able to meet high power density needs. All models, except one very basic unit, include a hydraulic-magnetic circuit breaker, surge protection, and EMI filter.
Optima 329 Series ↑
The 329 Series 0U units in full-rack and short-rack lengths are designed more for computer-based and other electronic equipment environments where EMI protection is not needed. The 0U size doesn’t allow enough room for EMI filters, but surge protection is still included as are hydraulic-magnetic circuit breakers. Designed for medium power density applications, they are available in 20A and 30A models in 120 1Φ Vac or 100–240 1Φ.
