Optima™ Basic PDUs
Product SelectorOptima 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 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 standardized product lines.
Protects Equipment
- EMI filter standard on 2U, 3U; optional on 1U models.
- Remote on/off/EPO standard on 2U, 3U; optional on 1U.
- Surge suppression on all models.
- Circuit breaker(s), inlet power indicator(s) on all models.
Multiple Configurations
- 18ga steel enclosure in 1U, 2U, 3U, and vertical 0U sizes.
- Outlets include 5-15, 5/L5-20, 6/6L-20, C13, C19.
- Inlets for 120/208 3Φ, 100–240 1Φ, or 120 1Φ Vac.
- Inlet at front or rear for 2U and 3U models.

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.
