Open-frame power supplies suit space-constrained needs

The CLP0224FP and CLP0112FP compact low power (CLP) family of ac/dc power supplies provide 200-W output power. The CLP0224FP, 200-W, 24-V power supply delivers efficiencies of >90% in a 2-by-4-in. footprint at 18W/in.³ while the CLP0112FP offers similar efficiency levels in a comparable footprint but at 150-W and 12-V. The density and thermal performance is achieved with Class B conducted emissions performance.

Both power supplies deliver 90% efficiency at typical and full-load outputs and at temperatures up to 50°C with operating temperature range from -40° to 85°C. With an 80 Plus Gold efficiency rating, the power supply minimizes losses at low loads, helping to reduce operating expenses. The supplies also leverage zero-voltage switching techniques in conjunction with quasi-resonant power factor correction circuits. 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). Additional protection features include over-current, over-voltage and over-temperature protection.
