JRE PEM-1 Filtered Power Entry Module

The JRE PEM-1 delivers clean, RF-filtered AC mains power to equipment inside an RF shielded test chamber — letting your device under test run on wall power without opening a hole in the chamber's shielding.

• Standard IEC 60320 C13/C14 connectors — swap cordsets to operate worldwide on any local mains
• 120/240 VAC, up to 10 A (≈1,200 W at 120 VAC) — ample for any benchtop test load
• Multi-element L-network filtering on each AC line: series broadband ferrite chokes feeding a feedthrough capacitor that shunts line-to-chassis
• Feedthrough construction holds filtering performance up into the GHz range, where an ordinary leaded capacitor goes inductive and quits working
• ~80 dB conducted attenuation, 30 MHz to over 6 GHz
• Low earth leakage — ≈136 µA at 120 VAC/60 Hz, ≈226 µA at 240 VAC/50 Hz — well within standard touch-current limits
• Integral MOV surge clamp protects the filter capacitors against line transients above ~480 VAC
• Every capacitor hipot tested at 750 VAC before assembly; the completed module tested again at 700 VAC
• Rugged machined-aluminum housing
• Works with any RF test enclosure or screen room

The PEM-1 is the simplest way to get AC power inside a sealed test chamber. Order it with a matching JRE outlet strip and the installation is fully turnkey — we wire a mating C14 plug onto the strip, plug it into the PEM-1, and mount the strip to the inside wall of your enclosure. No adapter cords, no field wiring; you just run your local power cord to the wall outlet and you're live. The standard IEC 60320 connectors mean a simple cordset swap takes you to any mains standard in the world. Ordered on its own, the PEM-1 ships with a mating C13 cord connector for the inside of the chamber.

Reliable shielding starts at the mounting. The PEM-1 secures to the enclosure wall with a ring of 4-40 screws (drilling template included for standalone installation), drawing the filter flange flat and tight against the wall around its entire perimeter. We have tested competitive filters that use a single center hole and a large securing nut — those are prone to leakage, because the coarse nut thread never seats the body reliably flat, and a single mechanical anchor works loose over time. Even a tiny loss of contact pressure opens an RF leak. Every PEM-1 specification is measured with the filter installed in an enclosure, and it holds that performance no matter how many times the connector is mated or the filter gets bumped and jostled on the bench. The compact footprint also leaves room for more filters on the same I/O plate.
