Six protected outlets and USB charging

The CyberPower CSP604U provides six NEMA 5-15R outlets rated for 125V input and two USB ports delivering a combined 2.1A for mobile devices. A 4-foot cord with a NEMA 5-15P plug reaches wall outlets in home offices or entertainment centres. The unit weighs 1.15 lbs and measures 1.48 by 2.20 by 11.57 inches.

Sustained surge handling and noise filtering

A 1200-joule MOV rating and 60000A maximum spike amperage absorb repeated transients without degrading after a single event. Protection modes cover line-neutral, line-ground and neutral-ground paths, while the EMI/RFI filter operates from 150 KHz to 100 MHz with up to 32dB attenuation. A 15A circuit breaker adds over-current protection for connected equipment.

Thermal behaviour and power draw in normal use

The suppressor draws no measurable power when idle and generates no audible noise during typical operation. Clamping voltage is specified at 400V, so excess energy is diverted before it reaches attached devices. Auto-shutdown cuts output after a catastrophic surge until the unit is manually reset. Certifications include UL1363, UL1449 3rd Edition, cUL and RoHS compliance.

Questions about this item

How loud is the EMI/RFI filter when the CSP604U runs all day?

The filter operates silently with no fan; it reduces line noise between 150 KHz and 100 MHz by up to 32 dB while the six protected outlets and two 2.1 A USB ports stay active.

What must I already have to use the CSP604U?

A standard NEMA 5-15 wall outlet for the 4-foot cord and devices with NEMA 5-15P plugs or USB cables; the unit supplies six surge-protected receptacles and two 2.1 A USB charging ports.

Will the CSP604U protect older gear that only has two-prong plugs?

Yes — the three protection modes (L-N, L-G, N-G) and 400 V clamping voltage cover all six NEMA 5-15R outlets, so legacy equipment connected through adapters still receives the full 1200-joule rating.
