quiet support equipment

Hello All, I'm testing a Class B computer peripheral and looking for recommendations as to 'quiet' support equipment that I can obtain in the USA. I'm looking for an Intel based computer; laptop or table top, ethernet card (NIC) monitor. 10/100 base-t hub printer So far, I plan to go with

info on AS4295

Is the only way to obtain a copy of the Australian standard AS4295 to buy it from the ACA? Could anyone provide me with a synopsis of the requirement for radio receiver sensitivity of -113dBm for a SINAD of 12dB? Susan H. Beard 321-435-7762 Fax 321-435-7957 susan.be...@gehh.ge.com

Hi Ed, A quick clarification on North American CO float voltage - it can go to -56.7 Vdc per ANSI T1.315:1994. AT&T NEDS allows -57.5 Vdc. These DC/DC converters are rated to -75 Vdc to cover European "60 V Station Battery" applications (the voltage can go as high as -75 Vdc per ETSI ETS 300 13

RE: DC/DC Convertors for CO Equipment

Jody, How can you consider the C/O DC output SELV when the battery charger float voltage exceeds the SELV limits (72VDC)? I believe this is why the DC/DC converters are rated up to 72VDC. I have always considered the 72V input a hazardous secondary voltage, and either required reinforced insulat

RE: DC/DC Converters for CO Equipment

Jody, My understanding is that the Centralized DC supply is only SELV (w/ Energy Hazard) if it has reinforced insulation to the mains supply, otherwise it is considered ELV. To exercise control over this, the manufacturer can place in the installation instructions the requirement for reinforce

Dear All, The folowing confusing excerpt is from a 36-72 Vdc rated dc/dc convertor NRTL report which I have seen numerous times. My question to all of you is can this dc/dc convertor be used in an 36-72 Vdc centralized power equipment to provide SELV voltages. The input power supply is the CO sup

RE: New Immunity/ESD Specs.

EN55024 also specifies a number of discharges at each point, 50 I believe, that didn't exist before, but the levels are the same, and they state a preference for contact discharges rather than air. There's been a bit of discussion about that recently on this list server so I won't go into that
