DC-Input Font-end Power Modules Meet Telecom-standard
Emerson Network Power launched four DC-input bulk front-end power modules for systems that use distributed power architectures. The modules add DC-input options to the company's DS series of power supplies. The DS450DC, 550DC, 650DC and 850DC modules all feature a very wide 40V DC to 72V DC input voltage range, which is suitable for telecom and central office applications operating from 48V battery plants. All four modules produce a main +12V DC output, together with an auxiliary 'always-on' +3.3V DC output for applications that require standby operation. The power modules incorporate fan cooling and have an ambient operating temperature range of +10°C to +45°C, with 50 percent derating at +70°C. The modules comply with all applicable EMC immunity standards, including EN61000-4-2, -3, -4, -5, -6 and -11. The power supplies carry UL/cUL60950-1 and EN60950-1 VDE safety approvals. Pricing starts at $418 for the DS450DC and $498 for the DS850DC, in quantities of 250.
