low profile, economical, enclosed power supplies with PFC
The RSP-320 Series consist of 320 Watt, low profile (30mm), enclosed type, 1U switching power supplies with universal (works world-wide) AC input and an active PFC function. By reducing from the height from the original SP-320 series (50mm→30mm), RSP-320 are 40% smaller in size and 1~9% more efficient. The -30~+70 °C operating temperature range is also wider than the -20~+65 ºC range of the SP-320 series.
When comparing performance and size, RSP-320 series are generally superior to the SP-320, especially for end users with limited space for installation and who are seeking additional energy savings. With state-of-the-art, high frequency / high efficiency circuit topology, the RSP-320 series is equipped with an active Power Factor Correction (PFC) function (PF > 0.95) and is up to 90% efficient. The series can provide full output power in ambient temperatures from -30 °C up to 50 °C (122 ºF). Cooling is silent, fan-less, natural convection. Operates up to +70 °C with some de-rating (see data sheets)
In order to operate more reliably in humid and dusty environments, the RSP-320 series are available with an optional conformal coating which provides basic protection from moisture and dust by applying a coating material on the PCB. The part number will read “RSP-320-(Voltage) CC.” Contact us for price and lead-time for these.
To meet the needs of LED display manufacturers, and others, seeking both a low profile design with low output Voltages, RSP-320 Series is available in 2.5V, 3.3V, 4V, and 5V (60A) models for optimal selection.
Built-in functions include fan speed control, protections for short circuit, overload, over voltage and over temperature. Simple ±10% voltage adjustment by easy to reach rheostat on terminal strip allows quick fine-tuning. All versions comply with UL, CUL, TUV, CB, and CE regulations that ensure users' safety. Additionally, RSP-320 is CCC approved (China Compulsory Certification).
