Eaton PDUMH20-ISO – Metered PDU with Isobar Surge

Product Overview

The Eaton PDUMH20-ISO is a 1U metered rack PDU that pairs real-time local current monitoring with premium ISOBAR network-grade surge and noise suppression. Rated 120V at 20A, it distributes power through 12 NEMA 5-20R and 2 NEMA 5-15R outlets from an L5-20P input, making it a strong choice for server rooms and network closets that need both power distribution and protection from AC line disturbances on the same unit. The digital display and front-panel status LEDs give facilities staff a fast way to confirm load and protection status at a glance. This metered surge-protected PDU suits environments where connected network equipment needs extra safeguarding from spikes and line noise.

Product Description

This 1U rack-mount PDU combines real-time output current monitoring with ISOBAR-grade surge suppression in a single unit, reducing the need for separate metering and protection devices in a rack. The digital display continuously reports PDU output current in amps, helping prevent circuit overloads as additional equipment is added to the rack over time. Three front-panel LEDs report wiring fault, protection present, and line OK status, giving technicians an immediate visual check of both the electrical connection and the surge protection circuitry without needing a meter. Twelve NEMA 5-20R and two NEMA 5-15R outlets provide outlet flexibility for a mix of standard and 20A-rated equipment plugs, and the unit accepts an L5-20P input for connection to a 20A circuit. Construction uses a rugged all-metal housing, and the unit installs securely in a standard rack using the included mounting accessories. Because it combines isobar surge and noise suppression with local metering, this PDU is well suited to server rooms and network closets in areas prone to utility power fluctuations, where protecting sensitive networking and server equipment from spikes is as important as monitoring load.

Frequently Asked Questions

What does the ISOBAR surge protection add compared to a standard metered PDU?

It adds network-grade AC surge and noise suppression on top of local current metering, helping protect connected servers and networking equipment from line disturbances in the same unit.

How do I know if the surge protection circuit is working?

The front panel includes three LEDs reporting wiring fault, protection present, and line OK status, giving a quick visual confirmation without a separate meter.

What input circuit does this PDU require?

It uses an L5-20P input plug, intended for a 20A locking receptacle or circuit.

Can this PDU support both 15A and 20A rated equipment plugs?

Yes. The mix of 12 NEMA 5-20R and 2 NEMA 5-15R outlets accommodates both plug types.

Is this PDU suitable for a network closet with unstable utility power?

Yes, the ISOBAR surge and noise suppression is well suited to environments prone to voltage spikes or line noise that could affect sensitive networking equipment.

What warranty does this PDU carry?

Eaton backs this unit with its standard manufacturer warranty; contact Creation Networks for the current term and any extended coverage options.

Can Creation Networks confirm this PDU fits my existing 20A rack circuit?

Yes, our team can review your circuit and plug configuration before you order to confirm compatibility.
