Four-outlet surge suppressor for sensitive

The ISOBAR4ULTRA DUP provides four NEMA 5-15R outlets fed by a six-foot cord and rated for 120V AC at 12 amps. It is built for desktop computers, networking gear and telecom equipment that demand continuous clean power. The all-metal housing encloses isolated filter banks that suppress both normal-mode and common-mode surges.

Isolated filter banks

Two separate filter banks combine toroidal chokes, ferrite rod-core inductors, HF/VHF capacitors and multiple metal-oxide varistor layers to stop EMI/RFI interference generated by connected devices. The suppressor clamps at 140 volts RMS and reduces a 6000-volt test surge to under 35 volts, while delivering 40 to 80 dB of noise filtration across the band.

1440-watt load capacity decides if your gear fits

The unit supports a maximum continuous draw of 1440 watts at 12 amps, so the total power consumption of every device plugged into the four outlets must stay below that limit. Exceeding it will trip the internal protection and leave equipment unpowered.

Questions about this item

Does the ISOBAR4ULTRA DUP have any user-replaceable parts or indicators that signal when protection has been exhausted?

The unit has no user-serviceable components; protection status is not indicated by a replaceable module or visible end-of-life light.

What limits continuous load on the ISOBAR4ULTRA DUP before the circuit breaker trips?

The strip is rated for 12 amps and 1440 watts at 120 V AC; exceeding either value will cause the internal breaker to open.

How much heat or fan noise does the ISOBAR4ULTRA DUP produce when powering equipment all day?

It has no fan and generates only minimal warmth from its filtering components; the all-metal case passively dissipates that heat.
