Numerous Options ↑

• Smart and basic control platforms.
• Outlets include 5-15, 5-20, high tension C13, C19.
• Inlets for 120/208 3Φ, 100–240 1Φ, or 120 1Φ Vac.
• Digital power meter available for basic 1U models
• Remote on/off/EPO available on all 1U models.
• EMI filter available on all 1U models.
• Staggered outlet startup available for all 1U models.

Standard and Custom

• Over 100 standard configurations for 20 Amps.
• Another 200 models for 30 Amps and 15 Amps.
• Customize to get the exact features you need.
• Gain more control by customizing circuit branches, outlet switching, digital monitoring, and more.
• Save space by integrating different power sources and conversions in the same enclosure.
• Optimize enclosures to meet needs for installation, ergonomics, or even non-rack spaces.

Semi-standard PDUs

Semi-standard PDUs are products which were a custom design at one time, but which are now available to all customers. They include a variety of outlets, controls, and other options which offer designs distinct from the standard products.

20 Amp PDU Option Highlights ↑

With over 100 standard 20 Amp models across multiple product series, defining the options thoroughly is best left to each model’s dedicated web page or the Standard Products Catalog. However, here are a few highlights to glance over.

Standard Features

Every unit has a main breaker, a main power on indicator (1 for 1Φ, 3 for 3Φ), and a surge suppressor (details are in the catalog).

EMI Filter

Why choose to have an EMI filter? An electro-magnetic interference filter is one of a few tools which can be used to clean up noisy power signals in industrial-like environments. Most office/IT facilities would likely not need one, but in facilities with machine shops, conveyors, or other large electrical equipment being switched on and off, disturbances get introduced into the power signals throughout the building. Having an EMI filter at the PDU helps protect downstream equipment.

• For the 820, 520 series (1U), an EMI filter is optional.
• For the 320 series (1U), an EMI filter is standard.
• For all 0U models (839/829, 539/529, 329), there is no room for an EMI filter, so one is not available.

Remote Switching and EPO

The Optima remote switching/EPO feature is primarily designed for use with Marway’s Commander panels. A Commander panel may be connected to one or more PDUs, and thereby provide remote on/off and EPO functionality for several racks in unison. In all models, the utility outlets are not controlled by the EPO, but all other outlets are.

• For the 820, 520 series (1U), the remote EPO system is optional.
• For all 0U models (839/829, 539/529, 329), there is no room for the EPO system, so one is not available.

Staggered Startup

• The 520 series units (1U), have a special option which adds an approximate 2-second delay to the powering of the four Group C outlets. This can help reduce in-rush loads since the 520 has a single circuit breaker.
• All 8 Series smart PDU products inherently have a staggered powering of outlets during startup. Additionally, on-delays can be programmed uniquely for each outlet.

Custom PDUs ↑

• Overcome the limitations of standard PDUs.
• Gain more control by customizing circuit branches, outlet switching, digital monitoring, and more.
• Save space by integrating different power sources and conversions in the same enclosure.
• Improve safety by integrating external EPO and interlocks.
• Protect downstream equipment with integrated surge suppression, EMI filters, and more.
• Optimize enclosures to meet needs for installation, ergonomics, or even non-rack spaces.

Marway specializes in custom PDUs optimized to meet application-specific needs for industrial, military, and OEM applications.

Marway’s PDU optimization includes configuration of chassis design, common and specialty connectors, switches, circuit breakers, indicators, metering, remote switching, software, as well as the integration of properly matched EMI filtering, surge suppression, power conversion, and more.
