CyberPower P405UC Compact Surge Protector with USB Charging

Overview

The CyberPower P405UC is a compact, wall-mountable surge protector designed for small commercial deployments where you need clean, protected power for a handful of devices without eating up a full rack PDU budget. Four NEMA 5-15R outlets on a 15A/125V circuit, a 2.4A USB-A charging port, and 1500 joules of surge protection in a slim white plastic chassis measuring roughly 245mm × 102mm × 41mm — this is the strip you reach for when fitting out a security head-end closet, desktop workstation, or IP phone cluster. The P405UC pairs protection hardware with 32dB EMI/RFI noise filtering, which matters when sensitive NVR or access control equipment shares the same power rail with noisy switching supplies.

Key Features

• 1500J Surge Energy Rating: This is the joule capacity available to absorb a transient surge event. At 1500J, it handles typical residential and light-commercial voltage spikes — a lightning-induced surge on a nearby line or a brownout recovery transient. It is not a whole-building suppressor; pair it with a whole-panel surge device in high-exposure installations.
• 4 × NEMA 5-15R Outlets at 15A / 125V: Standard three-prong outlets supporting up to 1875W peak combined load. Enough to power an NVR, a PoE switch, a monitor, and a router at a compact surveillance head end without overloading a single 15A breaker circuit.
• 2.4A USB-A Charging Port: The integrated USB port delivers 2.4A — fast enough to charge most tablets at full rate and smartphones significantly faster than standard 1A adapters. Frees up an AC outlet for a device that actually needs it rather than burning a slot on a USB wall adapter.
• 32dB EMI/RFI Noise Filtering: Switching power supplies, variable-frequency drives, and motor loads inject noise back onto the power rail. At 32dB of attenuation, this filter meaningfully reduces that noise before it reaches downstream equipment — relevant when security appliances, IP phones, or audio gear share the same strip with UPS units or other switching hardware.
• Integrated Circuit Breaker (15A): The thermal circuit breaker will trip before the AC circuit breaker upstream does, giving you a local reset point without tripping the entire branch circuit. Particularly useful in closets where the panel is a floor away.
• 1.8m Cord Length: The 6-foot cord gives enough reach from a wall outlet to a desk or rack shelf without requiring an extension cord in most standard office and equipment room layouts.
• Compact Form Factor: At 245mm deep, 102mm wide, and 41mm tall, this strip fits on a shelf, under a desk, or in a shallow equipment cabinet without dominating the space. The white finish suits visible desktop deployments without drawing attention.
• Compliance — FCC, ICES, cETLus, RoHS: The cETLus listing is the relevant safety certification here — ETL-Listed devices have been tested to the same UL standards as UL-Listed products and are accepted by AHJs (Authorities Having Jurisdiction) across North America. RoHS compliance matters for installations in government or education facilities with environmental materials requirements. FCC and ICES mark confirm the EMI filter meets conducted emissions limits so the P405UC does not become a noise source itself.

Integration & Compatibility

The P405UC is compatible with any equipment using standard NEMA 5-15P plugs on 120V AC circuits — IP cameras with local power adapters, small NVRs, managed switches, access control panels, IP intercoms, and general office equipment. The 15A circuit breaker is rated for the full 125V/15A North American outlet standard. The USB port does not support USB-C or Power Delivery protocols; devices requiring USB-C or more than 2.4A charging should use a dedicated charger. This strip is not a UPS — it provides no battery backup and will not hold equipment online through a power outage. For installations requiring runtime during outages, pair it with a CyberPower line-interactive or standby UPS upstream and treat this strip as a downstream outlet expander with surge protection and filtering. The 1.8m cord is not field-replaceable.

Frequently Asked Questions

Q: Does the P405UC provide battery backup during a power outage?

A: No. The P405UC is a surge protector, not a UPS. It provides surge suppression, EMI/RFI filtering, and USB charging, but offers no battery backup. If runtime during outages is required, install a UPS upstream and use the P405UC as a downstream outlet expander.

Q: What is the maximum total load the P405UC can handle?

A: The P405UC is rated at 125V / 15A with a peak power of 1875W. The integrated circuit breaker will trip if load exceeds 15A. Do not exceed this limit across all four outlets combined.

Q: Is the USB port on the P405UC compatible with USB-C devices?

A: No. The P405UC includes a USB-A port rated at 2.4A output. USB-C devices can be charged using a USB-C to USB-A cable, but Power Delivery (PD) fast-charging protocols are not supported.

Q: What certifications does the P405UC carry?

A: The P405UC holds cETLus, FCC, ICES, and RoHS certifications. The cETLus mark confirms it has been tested to North American safety standards and is accepted by AHJs across the US and Canada.

Q: How much surge energy protection does the P405UC provide?

A: The P405UC is rated at 1500 joules of surge energy absorption. This is suitable for protecting equipment from typical transient surges. For high-exposure outdoor or industrial environments, a dedicated whole-panel suppressor should be installed upstream.

Q: Does the P405UC filter electrical noise from the power line?

A: Yes. The P405UC includes a 32dB EMI/RFI noise filter that attenuates conducted interference on the power rail before it reaches connected equipment — useful when sensitive electronics share a circuit with switching power supplies or motor loads.
