Open-Frame AC-to-DC Power Supplies

GE's Critical Power division recently announced two new additions to its open-frame, Compact Low Power (CLP) family of AC-DC power supplies: its CLP0224FP and CLP0112FP. These new solutions complement the previously released CLP0212FP solution, a 200W, 12V ac-to-dc solution. The CLP0224FP, 200W, 24V power supply delivers efficiencies of greater than 90 percent in a compact, high-density 2-by-4-inch footprint at 18W/inch3. The CLP0112FP offers similar leading efficiency levels in a comparable footprint but at 150W and 12V.

Both CLP0224FP and CLP0112 deliver power efficiency of greater than 90 percent at typical and full-load outputs and at temperatures up to 50°C (122°F), with higher temperature operation possible at derated output. With an 80-Plus Gold efficiency rating, the power supply minimizes losses at low loads, helping to reduce operating expenses. In addition, the CLP-series power supplies employ a unique design approach for their power level, leveraging zero-voltage switching techniques in conjunction with quasi-resonant power factor correction circuits.

Examples of these space- and airflow-constrained applications include small-cell remote radio head, small- and medium-sized routers and switches, ATM machines, time stamp card readers, outdoor billboards and signs, LED lighting, stage lighting, audio speakers and test and instrumentation equipment (oscilloscope). The CLP-family's advanced thermal management capabilities also contribute to its wide range of possible applications.

The CLP's fanless conduction-cooling feature increases the power supply's reliability since there are no moving parts. With heat-generating components deliberately placed on the bottom of the printed circuit board, GE's new CLP-series power supplies enable heat removal to be maximized using heat sinks. These factors contribute to a single CLP module being able to support an extended temperature range of minus 40°C to 85°C. Additional protection features include over-current, over-voltage and over-temperature protection.
